I've been seriously considering getting one of these for my monster and losing nearly 7lbs for under $200, but thought I'd see what experiences others have had with them. Anybody have one yet?
http://www.shoraipower.com/s-42258-Monster-696.aspx (http://www.shoraipower.com/s-42258-Monster-696.aspx)
I'm thinking about getting one too. from what i've seen at the track with a twin you have to make sure that you get the one for a twin. the inline 4 one won't start a twin. losing 7lbs seems like a no brainer for a race bike for only $200. between the new plastic tank, wheels, rotors, and a battery i'm hoping to lose 20-25 total. [evil]200 beans is nothing compaired to the amount for wheels that lose a similar amount [bacon]
yeah, on their site, you can put in the bike, year, model and it recommends 3 batteries; a standard, endurance and race. I think I'm going to go with the standard that it recommends for the 696.
these guys are at the mtorocycle shows this year, i have to check them out.
the dimensions and such from the batteries seem too good to believe, if they work like they should it would be really cool, i'm curious as to what the downside of the batteries are, beside them costing a bit more.
i want one too.
i plan on ordering one for the other M900 in my garage as a guinea pig before month's end.
Light is right.
I will update my battery to a similar product now available down here from Carbon Imports. Dropping three kilos appeals big time. The batteries I am looking at are on a thread in OZ Monsters. They appear different externally, but I'm not sure if the technology is the same.
If the claims about the batteries are correct then they are worth the price.
30$ a pound to lose sprung weight? are all you guys so fit that you couldn't lose 7lbs by eating better? [laugh]

New Shorai Lightweight Batteries (http://www.ducatimonsterforum.org/index.php?topic=45035.0)
"and don’t mind a slight increase in weight and cost compared to the standard recommendation"
I think their wording is wrong. Shouldn't that say a decrease in weight?
edit: I guess they mean an increase over their own standard battery - sorry.
That is a really nice battery.

3kg loss from battery and 3kg loss from Christmas cheer! :D
I installed my new Shorai battery in my 696 yesterday. I guess I'll be the Guinea pig. :(
The light weight of the battery makes it seem almost fake. The case is made of thick, very durable plastic, which seems to be the batteries major source of weight.
This is my third battery in three years, if the Shorai gives my more than a year of service, for me, it's money well spent.
Great, keep us posted danaid! [thumbsup]

Ordered one last night. :) will probably install next week. This bike already felt incredibly light, now with my mods this winter, I think it should be about 13-15lbs lighter. I would guess that to be a noticeable difference.
When upgrading your battery, I would consider more AH and CCA before weight. Less weight is a benefit but not necessary. If it had less AH/CCA than OEM but weighed less, it would need to be charged more often and will be stressed more from starting. In that case, it wouldn't be worth it to me. But, looking at the options for the batteries you were considering, it seems all of them exceed the OEM specs.
Some alternate batteries from another post:
Yuasa YTZ12S (11 AH, 210 CCA, 8.1 lbs.), $175
Odyssey PC680MJ (19 AH, 280 CCA, 15.4 lbs.) $154, metal jacket for high heat.
Odyssey PC680 (17 ah, 220 cca, 14.9 lbs). $134.
More weight but way more AH and CCA.

I have one for my SV track bike, but I haven't fired up the bike yet. They are almost laughably compact and light. I was advised that one of the tiny ones would be fine for a race bike, but I decided that I could handle the extra four ounces ;D

New toys are fun; losing weight isn't. But since you asked, I've lost 15 lbs. since last summer :P
I use the Yuasa YTZ12S on my S2R1000 and have never had problems with starting. I do keep my bike on the tender though.
We've been using the Shorai for awhile now. They work very well.
http://www.ducatimonsterforum.org/index.php?topic=45035.0 (http://www.ducatimonsterforum.org/index.php?topic=45035.0)
We've used the YTZ7S, Oddyssey 310 and the Speedcell batteries on our project bikes. Up to this point the Speedcell was our favorite. The Shorai works as well as the Speedcell but they work a little better in cold and should be more durable. The Shorai batteries are lighter, less expensive, more amp hours and have a good warranty.
We recomend the Shorai Lithium Iron LiFePO4 Battery LFX14A1-BS12 for most monsters.

QuoteWe are testing it on our own bikes so we have first hand experience--but the company has been using these batteries in aviation and submarine applications for 9 years - so they have been subject to some extreme testing already.
Sounds good.
Talked to the Shorai folks at the DC IMS and they were pretty cool. They had a traditional lead battery next to one of theirs and the weight difference is impressive: it felt as if theirs was full of air! :o
They suggested buying from batterystuff.com (http://www.batterystuff.com/search.php?q=shorai&x=11&y=9) since they offer free ground shipping, not just on Shorai batteries btw.

The biggest Shorai battery everyone is talking about on here has a 18ah and 270cca but only weighs 2.10 lbs. You get all the power you need and the weight savings. These batteries also don't lose power like a normal one does just by sitting.
Well, looks like it's a very convincing option! I'll add it to the top of my list. I'll likely wait til my oem battery starts to weaken. No sense replacing a good battery.
Also, the new battery cable upgrade kit would be a great mod.

We were planning to create our own line of battery cables when we came across the motoelectric hi-capacity cables. These are better than anything we could make, they are very complete and work very well.
http://www.ducatimonsterforum.org/index.php?topic=45690.0 (http://www.ducatimonsterforum.org/index.php?topic=45690.0)
got my shorai today. Going to put it in later this evening I hope.
Installed. Starts up great. I weighed both batteries when I had them out and there's exactly a 6lb difference. There's also a size difference as shown here, but the Shorai came with a ton of dense foam with sticky backing. Impressed so far.
(http://www.dgmphotography.net/forumpost/Jan2011/photo.JPG)
Shorai makes a smaller 14 battery if you want to mount it somewhere else other than the stock location. It has the same power as the larger 14.

Does the little one weigh less again? I would like a battery in the sub 1kg range for my M900 if possible. I do have JE high comp pistons, but have the Euro switch gear to have the headlight off while starting, vacuum fuel pump and basic igniter ignition. What's the smallest I could go?
They are all sub 1kg. Even the biggest one.

The weight is almost the same between the smallest 14 and the largest 18 battery ( 2.1-2.2 lbs).
I would use the larger 18 battery because it has more starting power for the high comp piston. It also has more reserve and should last longer.

depending on which way your battery posts are configured.
mine weighs exactly 2lbs according to my scale and my original batt weighs exactly 8lbs on the same scale. I believe 2lbs is .9Kg right?
yes. 0.907
I got a 14 Ah and just tested it today, I used it to start up both of my bikes (the 900 with FCR and the 750 with Mikuni carbs) after they had been sitting for about a month: no problem with either bike.
If I had a fuel injected bike with high comp pistons, I would definitely get the the 18 amp battery, but otherwise I think the 14 is just fine. [thumbsup]
Here's some pics: packaging (keep it! you'll need it to fit the tiny battery) and weight (in grams) 4430 vs 700 about 6.3 to 1 ratio! :o

Is there any downside (besides cost or weight) in using a 18ah in my s2r800 even though it probably only needs a 14ah?
I am still on my stock battery. My bike starts but not as good as it used to.
I got the 18 for this fixer upper 99 900 because it needs all the help it can get. Even it is silly light - no weight penalty compared to OEM! I will test it when the wiring is sorted out soon

As far as I know, the 18 Ah is just a little heavier and costs about $30 more than the 14 Ah, that's all.
and has more starting oomph.
or so i think. (i did bad in circuits in college, 'lectrics is all IZ_ math. but not this (http://en.wikipedia.org/wiki/IZ__mathematics) kind of IZ_ math.)
Between Motorwheels and Batterystuff I found three different 14AH model designations, any one know what the difference is?
LFX14A1-BS12
LFX14L2-BS12
LFX14A2-BS12
i know one of them is [ + - ] and another is [ - + ] orientation of the posts.
Dunno what the last one would be.
do these ever go bad after being discharged for a while like normal batteries? as in say you dont charge it for a year... it's totally dead... you should be able to just hook it up to a tender and have it recharge right? since it's lithium ion like a phone battery?
from the guys at Motowheels: These don't discharge at the same rate as the OEM style battery, instead of losing say 10% in a month, these lose much less, like 1%. something like that. So its like likely that you will discharge it from nonuse.

hmmm... that's kind of interesting then... so say, worst case scenario, you can leave it for about a year and a half off a tender @ 5% discharge per month...
the reason this is good for me is that i might be traveling btwn countries a lot soon and the bike might have to sit for a long time without access to a tender... unless i can get a friend of mine to let me store it in his garage.
Newer Monsters that came with a Yuasa 12B-BS battery take the [ + - ] configuration, whereas older Monsters originally equipped with the lead anchor known as the "16 series venting piece of shit" (or at least I think that's what the packaging said) use the opposite: [ - + ] (the positive terminal is next to the belt side, and the battery is oriented upright)
Here is the break down
LFX14A1-BS12
14 = the a/Hr
A = orientation of the posts ( A is [+ -] L is [- +] )
1 = case size of the battery (1 is the bigger one, 2 is the smaller one)
12 = the voltage
wizard!

According to the Shorai guys at the motor show: unless you have a constant draw of electricity the battery can sit for a year and will be just fine.
If you have an immobilizer or something else that draws, you should disconnect the battery.
Good policy anyhow on a monster in storage since it is so easy to access.
you guys make my bank account cry :( haha
as a follow up I got a chance to ride a little bit last weekend and wow. I can't attribute it all to the battery, but between the 6 lbs lost in battery, 6lbs lost in exhaust cans and the new DP racing ECU... my 696 is like a new beast.
Got my Shorai in the post last night, and installed it this morning. Bike fired right up once installed. Too bad it was such a pain in the ass to get to.
Quote from: thought on February 17, 2011, 10:56:21 AM

Think of it this way: for less than $100 you drop over 8 lbs from your bike. How many mods can do the same for that amount of money? And no, getting rid of the exhaust cans does not count! [cheeky]
I was looking for a LFX18A1-BS12 but they seem to be out of stock everywhere I try. Where have you guys been buying them?
I got mine from Motowheels - try calling 'em up
I got mine from batterystuff(.com)
With a Duc with an immobilizer, and a BMW with an LCD clock, are there any issues with just leaving the bike plugged into a battery tender with a Shorai?

I have a Speed Cell in the Monster.
that is so 2010.
thanks for the suggestions, but tried all those, everyone is fresh out. must be a popular item, or someone is having production/distribution issues...
indeed. tried shorai directly?
might give 'em a phone call for ETA. urge them to either sell direct to you or to put your favored supplier higher on the fulfillment priority list.
haven't tried calling them, just checked their website. the website actually let me put it in my cart, go through the entire checkout process, then when i hit "submit" it just removed it from my cart saying it was out of stock. i did see on some reseller's website a note saying that the US distributor was fresh out and nothing would be available before mid march.
hmm. well luckily that is a short time away.
I think I got mine directly from shorai.
this'll be my next winter's mod i think... haha
just got mine in the mail....can't ride for a bit, but it's making me want to rip the tools out.
waiting for some tubes to come shortly, then do it all at once
Well looks like I am going to get a 14ah version. I bid on one on eBay for the hell of it figuring I would get outbid but I won. I wanted to get the 18 even though the 14 is fine for starting my bike. oh well..
Cool - walking distance from work. Maybe I can pick one up when the revised version is ready.

Production Delay Announcement
Shorai LFX have gotten tremendous reviews from our customers who have used them, and our initial sales were much higher than expected. We are currently out of stock. We have decided to upgrade the LFX batteries, including tougher terminals which are 50% thicker and do cell revisions for even better performance at high and low temperatures. But we are facing a substantial delay due to the new tooling required, and so it is likely that we not be re-stocked with LFX again until about the middle of April 2011.
We will post an announcement a few weeks before the next shipment arrives, and will re-enable the “Buy†buttons on the Shorai website then.
We apologize for the delay. In the long run, we believe that continuing to improve the best powersports battery can only be a good thing for all. Thank you for your patience and understanding.

Someone earlier asked if it is okay to leave it on the tender like some of us do in the winter time( -40 degrees Celsius) without any consequences. Anybody know the answer to this one? I know some lithium batteries don't like being"over charged." Weight savings look great, what is the math here, 10 pounds equals one horsepower?

Speedcell (that uses a123 cylindrical cells) says no
Shorai said it is OK- but I noticed the small 1.5 amp chargers do nothing to charge the batteries. We use a ODYSSEY Ultimizer Battery Charger/Maintainer: 6amp (http://www.motowheels.com/italian/myProducts.cfm?parentcategoryid=915%7CBatteries%20and%20Battery%20Accessories&productID=6727&showDetail=1&categoryID=915%7CBatteries%20and%20Battery%20Accessories&vendoridtodisplay=0&filterFor=&collection=) to set up the batteries and then never put a charger on it again.
If you have a constant drain from an alarm, I would use at least a 6amp maintainer.
We just ran out of the Shorai last week. We put in a big order with them. We should have plenty.
We are offering 10% off on all pre-orders.

Price, and the two year warranty was what directed me to the Shorai battery. I debated on getting the full spectrum battery especially because it is made in the U.S. but no warranty.
Finally installed today and I am very happy. Bike starts better then it has for a while. I am do for my 12k service so I can't wait to see how it works after that. One of the best things is it is so small I was able to fit my PCIII and the battery in the battery tray. This is great because before my PCIII was zip tied to the top of my open airbox just kind of hovering. I can't wait to see how the next couple of cold starts are now that the battery is probably all charged up.

The shorai site has a
FAQ (http://www.shoraipower.com/t-faq.aspx) section that answers many questions. Even in the winter I start up my bike at least every couple weeks and let it run for a bit, and I don't really worry about it. From what I understand from their FAQ: if your bike is going to sit for more than a couple months, you might want to hit it with a tender, but it shouldn't be necessary. If you have an alarm or a clock, just disconnect the battery and the above should work for you as well.

I think this equation applies mostly to wheels (tires, rotors), not to parts of the bike that don't move. Still reducing weight is always good! [thumbsup]

webbikeworld review of the battery... not a real review per se, but it has some good info in there.
in the comments section, the part that caught my eye is that if the battery drops under a certain charge, you'll have to get a new battery... so keeping it on a tender is a really good idea. or at least making sure you run it for a while if you dont have access to a tender.
Isn't that kind of a moot point considering it is not suppose to lose 1% of its charge over a year just by sitting?
Shorai finally got a pic of the charge up but still no price. Expected to be available between April 15th and the 29th
(http://www.shoraipower.com/images/product/large/184.jpg)
Is the Shorai company headquartered in Japan? Sounds like a Japanese name. I wonder how the recent disasters are going to impact their production timeframe.
Good question.
I got some Aella products recently and had no difficulties communicating back and forth or getting my stuff shipped, so it really depends on where they are.

New ETA is early May.

Moto: will the charger be available for 220V with Euro wall plug?
do you have weight savings listed?
I have one coming to replace my speedcell on Monday. Bought it from moto, excellent service as usual.
Do they come with a balance plug?
Also, if the pricing is less than $50 for a charger, great. If not, you can buy a decent digital charger that will work for 40-50 and will also work for Lipo's, nicad and niMh, as well as FE (regular) batteries.
The Shorai batteries for our bikes weight between 1.61 and 2.28 lbs.
The stock batteries on older monsters ( Battery: YB16AL-A2 ) weigh about 11 lbs
The stock batteries on late model monsters after 2000 (Battery: CYT12B-BS ) weigh about 9 lbs.
So one can save about 7-9lbs of weight by going to this battery.
Keep in mind smaller batteries will have less reserve capacity--so you don't want to leave the lights on when parked. If the bike has a constant draw from an alarm, you should keep it on a 2 AMP or higher battery maintainer.
Shorai has just released a new maintainer for their battery:
(http://www.motowheels.com/italian/images/lg330674941.jpg)
Shorai Dedicated Battery Management System (http://www.motowheels.com/italian/myProducts.cfm?parentcategoryid=915%7CBatteries%20and%20Battery%20Accessories&productID=9186&showDetail=1&categoryID=915%7CBatteries%20and%20Battery%20Accessories&vendoridtodisplay=0&filterFor=&collection=)
I know the smaller 1.5amp battery tenders don't work well with the Speedcell. I was told to use a 6amp or higher for those. We used the ODYSSEY Ultimizer Battery Charger/Maintainer: 6amp (http://www.motowheels.com/italian/myProducts.cfm?parentcategoryid=915%7CBatteries%20and%20Battery%20Accessories&productID=6727&showDetail=1&categoryID=915%7CBatteries%20and%20Battery%20Accessories&vendoridtodisplay=0&filterFor=&collection=) on the Shorai but have not used the new Shorai charger.
I have not seen anything for the euro wall plugs - I will check.
You don't need anywhere near 2amps to maintain a battery. Even a really hungry alarm won't pull more than 100mA (and most should be more like 20mA or less). Batteries tend to live the longest if not aggressively charged. I'd use the .75amp battery tender junior or .8amp waterproof tender.
I bought my battery 3 days ago directly from shorai (they are local for me). I had a long 20 minute chat with the owner about the charger (the battery wasnt my concern but the charging was).
So here's what I got out of the conversation.
1) Lead acid batteries due to their design, naturally stop accepting charge when they are full. So if you have a multi cell lead acid, a normal charger can keep pumping the same amps into the battery and the juice will go to the empty cells and not the charged cells. This means that lead acids are naturally self balancing.
2) LiFePo's dont work this way. If you have a multi cell lithium battery (like the shorai, ballistic, speedcell, etc), each individual cell will accept charge past its designed capacity. According to the owner, the shorai's have a built in overcharge protection to prevent this (which is good)
3) There's a catch. Lets say one of your cells is fully charged and three are not (aka charge imbalance). According to the owner, if one cell is fully charged, the overprotection circuit will prevent charging of the other cells (which are in series) to keep any one cell from going over its designed limit. Which means that the charge imbalance is not resolved and the other three cells are not fully charged. Over time this will lead to faster decay of the uncharged cells.
4) The shorai charger (and batteries) have a separate port (not the positive and negative leads of the battery) where they connect. This lead is tied into each cell directly not via series so technically each cell can be charged individually if there is a charge imbalance.
Bottom line, your battery will only be as good as its weakest link in the chain. Its like putting 1 good and one dead battery in your TV's remote control, it still aint going to work. Over time, all these batteries will have a charge imbalance. The owner was kinda walking around the issue by saying its not an issue if you use the bike regularly BUT its a small but important difference between lead acid and lithium style batteries that greatly affects longevity. Sure if you ride regularly this is going to be less of an issue but if you store the bike for the winter (like many of us do), its probably going to be better if you got the balanced charger than use a standard one that you may already have.
Since its coming up on summer I will probably hold off on buying the shorai charger until winter comes around. Ill be riding more frequently for now anyways.
I hope this helps clear things up.

It clearly says on the BOX in BOLD dont use trickle chargers or chargers with desulfication modes (this is a setting where excess voltage is applied to a lead acid to improve storage capacity)
I would follow the instructions on the box.

What does that mean? If my Scorpio alarm is left on for weeks, it's proven by me that it's bad for the battery. Unless I use a charger, which I can't with no winter storage outlet available. If it pulls 100mA - how long before a substantial part of the juice is drained? Is there an easy formula?

I agree and a battery tender isn't a trickle charger and is specifically approved by Shorai. I was just saying NOT to use a 2-amp charger as a prior poster said to do.

Not really because you cant quantify how much battery life is remaining. Realistically, the long term storage issue is resolved by just pulling the negative cable off the battery. Other option is to pull the battery and put it in the fridge if you dont want to charge. I doubt that helps you if you need to have the bike secured during storage. I opted for the LFX 18 model for the larger storage capacity.
battery fits like a glove. It conveniently has just the right amount of room for my power commander to slip right in next to the battery.
(http://s3.postimage.org/8hnxglfhk/IMG_1344.jpg)
Just checked the temperature under the tank after a ride and the battery was sitting at 110 to 140F. I'm curious to see what the life of these batteries is, as some literature (from FMA in Frederick, MD, USA) indicates a reduced number of charge cycles when operated at temperatures higher that 140F
Yeah im a little concerned about that too, but I'm wondering what constitutes a cycle. A lot of the battery tests I saw involved the LiFePO4 batteries as the primary source of power (like hobby planes, robots, etc) where these batteries are fully drained and recharged on a regular basis. On a normal street bike, its used for literally 2 seconds of juice before the alternator takes over. I dont know if those tests would have any correlation or not.
Guess we'll both have to wait and see.

LiFe batteries like the Speedcell and even some AGM batteries like Oddysey will not charge on a 1.5, .8 or .75 battery Tender. You are thinking about traditional lead acid batteries. The Shorai battery charger is 2 amps.
The Speedcell and most A123 batteries I have used like 6 amp or more to charge it. The little battery tenders tend to cause damage to the A123 batteries from our past experience. Speedcell does not recomend the small chargers less than 6 amp.

I see the LFX18 L2 is still out o' stock... i got one of themthere old Monsters using the "L" polarity, and my one-off battery box uses the case size "2". Any word when these will be coming in?
AND, the picture for the Shorai charger leads me to believe it can charge more than one... is that right or no? (looks like two ports on the side to me)
Got my shorai today. It's pretty remarkable how this small/light thing can replace a heavy lead-acid battery. Would take a gazillion dollars in Ti/carbon fiber/etc to match the overall weight reduction. Very impressive.

+1. Its not like they are mutually exclusive, you can lighten the battery
and upgrade other parts too
For a data point, I have been using an LFX18 to start and run our miata autocross/play car since Feb. It starts and runs the 2.0L motor effortlessly, and pretty much works just like a normal battery, even after sitting for 2-3 weeks. I've fully discharged it a couple of times accidentally with the key left in the ignition, and it charges back up nicely with a 6amp charge. It was over 20lb. weight savings in this application [thumbsup]

Just received my charger, that extra port is for charging 6v batteries with included cables.
Quotet charges back up nicely with a 6amp charge
What type of charger & f how many hours?
Just ordered an LFX18 and the charger.
I hate waiting! [bang]
Just installed a Shorai LFX18 in my S4.
Works good so far. :P
Think I'm going to pull the Shorai out of the Super Duke and put it in the SC instead. The battery placement on the KTM actually uses the weight of the battery to balance out the bike, and it handles better with the heavier unit in place.
I think you just need to remove some more counter-balancing weight so that its balanced again without the heavy battery (or re-tune your suspension to suit the weight loss from the battery) [evil]
There's not much that can be taken off the back of the bike to reduce any weight, so that option is out. Plus, the location of the battery box (inside of the chin spoiler, just behind the front wheel and under the axle height) would make it a bit more difficult to dial out.
Regardless, I'd get more benefit out of using the battery in the SC. :D

I suppose you could.
The only reason would be the cost, even the -18 is quite a bit smaller, and nearly 3 kg lighter than the OEM YB16AL-A2.
I've got no long term experience with these batteries, so no idea how they *really* compare.

The early 2 valve bikes (M900 included) has a weaker charging system and starter ratio that draws more power than the new bikes.
I would get the Shorai Lithium Iron Battery LFX18L1-BS12 (http://www.motowheels.com/italian/myProducts.cfm?parentcategoryid=915%7CBatteries%20and%20Battery%20Accessories&productID=8931&showDetail=1&categoryID=915%7CBatteries%20and%20Battery%20Accessories&vendoridtodisplay=0&filterFor=&collection=) . It will have more starting power , more reserve and last longe than a smaller battery. Still only weighs 2.12 lbs and measures 5.83"x2.6"x4.13".

You're asking for the high power in the small case.
Shorai doesn't appear to make that:

What bike do you have?
The application chart below will give you the correct application based on orientation of the terminals:
http://motowheels.com/downloads/shorai_2010.pdf (http://motowheels.com/downloads/shorai_2010.pdf)
Choose the largest battery offered if you are going to use it on the street. Some bikes do not have a smaller option.
There is very little weight difference between all the sizes. They are all smaller than stock so unless you are moving the battery to a different location, there really is no need to get a smaller size. I'd rather have the extra capacity.
-M
different location... using a yuasa 7 series right now, which is the same as the L2 in size and polarity.
Are you using a YTZ7S?
All of the Shorai have more cranking power than the YTZ7S.
The Shorai Lithium Iron Battery LFX14L2-BS12 (http://shorai%20lithium%20iron%20battery%20lfx14l2-bs12)

The LFX18L1-BS12 is slightly larger than the LFX14L2. If you can get it to fit, it would be worthwhile for the extra reserve capacity.

Yes, currently that yuasa - which turns over the standard compression fine, but could certainly be improved. I'll look into modifying the battery compartment I've made to fit the L1 size. I'd like to get the 18 if possible as I hope to run higher compression, and with flatslides, it doesn't exactly jump to life

I used to use the YTZ7S on a on a 944 motor with hi comp pistons, twin plug heads and flatslides. I would sometimes kill the battery trying to start it if I had not run the bike for awhile.
I now use the Shorai Lithium Iron Battery LFX18L1-BS12 (http://www.motowheels.com/italian/myProducts.cfm?parentcategoryid=915%7CBatteries%20and%20Battery%20Accessories&productID=8931&showDetail=1&categoryID=915%7CBatteries%20and%20Battery%20Accessories&vendoridtodisplay=0&filterFor=&collection=). No problems now.

I'm trying a Shorai LFX14L2-12. I chose the LFX14 coz it's the equivalent to the YTX12-BS gel battery I was running. It just became available down here. It turns my bike over no probs with Hi comp and FCRs. Strangely, it turns the bike over just as easily with the headlight on as it does with it off. Very strange. Maybe one of you sparkies can explain it to me.
It is small enough for me to run pods if I want coz I can fit the coils in the battery box with the Ignition as well. No special bracketry needed. 730 grams Vs 4 kilos. That's over 3 kilos from high on the bike. I wish I could drop weight off my wheels and tank that cheap.
I will try out the competitor brand when it becomes available down under and do a long term comparo so I know what to recommend to customers.
Koko,
That's normal re the light. Fancy batteries like the Shorai like to have a bit of draw to get them awakened from their slumber before they have to do the heavy lifting - think of it like your morning espresso or a warm-up before an exercise routine (shorai has a technical description on their site if the chemistry interests you). In fact on cold mornings you'll find it cranks better if you leave the headlight on for a bit before trying to crank the motor over.
That's amazing and caught me by surprise, for sure.
It is a good characteristic of the battery for bikes with hard wired lights as many down here have.
Cheers.
I have had the Shorai LFX18A1-BS12 in my 09 M1100 for over a month. After first installing the battery, it started up fine. I rode the bike to work and had a hard time starting the bike that evening to ride home. It sounded like it was turning, but the bike would not fire up. After about 10 tries, it worked. I figured it might have come from the factory on a low charge, they claim it comes 90% charged. So I hooked up the Shorai charger over night. After charging, I disconnected the charger and the bike sat for a week. When I went to start it after that, it fired right up. So I thought I had the issue solved. I took the bike for a long ride, about 500 miles, that day. A week later when I went to start the bike up again, it turned, but did not start. This time I tried 30 times, but it would not start. I ended up having to plug in the charger and wait. To its credit, the voltage on the battery started out at 13V and never dropped very much.
I took the bike in for its 7500 mile service at Nichols and asked them to check the battery or anything else it could be. They said the battery seemed to charge well, but that they would test it again. I told them that if they cannot find a reason for these issues to switch me back to a regular battery. I'm about to go for a 5k mile trip in a week and I do not have the patients for dealing with this issue.
By the way, I do not have any accessories on the bike that could be drawing the batter while it sits.

I am using Shorai's special charger which charges the cells in parallel not in series. I have always wondered what about when the bike charges the battery. Wouldn't the bike's alternator charge the cells in series?
Something is wrong with your charging system, the connection or the battery.
My shorai equipped bikes start everytime - even after sitting for months with no issues.

My charging equipment that seems to be having issues is my alternator, which worked fine for the stock battery, and the shop I brought my bike for service is a Shorai retailer who tested the battery. I also contacted Shorai directly with my story, but I have not heard back from them yet. It does not change the fact that I cannot use the battery and will most likely change back to stock.
I've heard these units can be susceptible to the cells becoming "unbalanced" (Whatever that means) but that the special charger is supposed to 'correct' that.
Sounds to me like a bad unit.

If I understand the Shorai correctly......
The charger charges each cell individually and makes the battery balanced (full charge to each cell).
Charging it by the bike's charging system, or a normal charger, brings the battery up to whatever charge the weakest cell can take.
If the weakest cell is first in the series, the total capacity won't be higher than this - the weakest link.
Not a perfect design - best solution would be a 'balancer' built into the battery - or use the charger 'all the time'.
Installed a Shorai battery on 6/20, 48,636 miles.
As of 7/20, at 49,261 miles, battery was dead.
Not coincidentally, my Regulator/Rectifier is dead.
Recharged the Shorai, swapped in a good used R/R.
We'll see what happens.

What are the signs of a damaged Regulator/Rectifier? At this point I just want to put a stock battery in and go on my trip. I really hope that I have not damaged my bike.

Voltage measured at the battery doesn't increase when the motor is running.
A complete test described here:
http://www.electrosport.com/technical-resources/library/diagnosis/fault-finding-guide.php (http://www.electrosport.com/technical-resources/library/diagnosis/fault-finding-guide.php)
There's no way a damaged regulator will damage your bike unless it's overcharging, in which case it'll just fry your battery.
If it's undercharging, then it's no different that a race bike insofar as some race folks will actually get rid of their charging system in favor of a "total loss" system.
I.e. They remove the alternator because of the weight it adds on the crank and the 1/3 HP it consumes in favor of a bike whose ignition and FI system only work as long as the battery has power.

If the bike is not charging the battery, you are going to have the same problem--the bigger battery will just take a little longer to run down.

My alternator is fine. When the bike is on, the volt meter shows 13+ volts. Which suggests that the Shorai is having problems being charged in series versus the parallel charging that the Shorai charger does. I switched back to a stock battery this weekend. In theory the battery sounded nice, but the more I thought about the in series versus parallel charging, I just do not see how they avoid unbalanced charging over the cells unless you are constantly plugging into their charger. I have contacted Shorai and will post when I hear back from them.
Shorai just got back to me and they will take the battery back an run some diagnostics. Since I am local, I will drop it off tomorrow and hope to hear something from them soon.

seems like they could easily fix it internally (but there'd be no need for their charger anymore), or make a wiring harness adapter to plug into that special port.
One potential issue (not sure if it's related to the others) is that the Shorai unit has a higher voltage than the stock charging system is designed for. This means one of the following scenarios can play out:
1. You don't use their charger. As a result, the 13.5 volts that the R/R limits the charging system to is insufficient to fully recharge the battery. In theory this isn't a problem--you'll just never have a battery that's charged to capacity.
2. You do use their charger. Daily. In this case, every single time you turn on the ignition, your R/R has to shed the excess voltage as heat. On my bike the alternator kicks out just barely 13.5 volts at idle, so it isn't really shedding anything as heat. Once RPMs climb it has to do its job, but it also has air flow. With the battery having been charged externally, you're starting out with excess voltage and the R/R starts draining it and heating up immediately.
Both of these scenarios are because the LiFePO4 batteries kick out, as configured, 14.4 volts fully charged (four 3.6 volt cells wired in series). They are considered discharged at 11.2 volts. Now don't get me wrong, converting excess voltage to heat is part of what the R/R is designed for. But in scenario 2 you're adding in the excess voltage from the battery, which the R/R simply drains and sheds as heat even when at idle.
For comparison, a typical lead-acid battery has a nominal charged cell voltage of 2.105-2.13 volts. Multiply this by 6 cells and you have a nominal fully charged voltage of 12.63 to 12.78 volts (which is what a charging system output of 13.5-14.5 volts is designed to handle). LiFePO4 batteries should be charged at 14.4 volts minimum.
This subject has actually been discussed at length on boat forums, where weight and ability to charge fully (via solar or wind) are important, and where loss of battery power is potentially more dangerous.A
My Shorai arrived with ~13.4V measured with a good DMM.
After sitting for a month in it's box it was still at ~13.4V (wanted to sort out some bike issues before installing).
Got the dedicated charger and hit the "charge" mode button. Got all the right lights and beeps and ~13.4V when complete 20min later. Put it into "store" mode where it's been for about a week now. Was expecting to see something closer to 14.4V, but perhaps the Shorai charger does not quite get it to 100% charge.
The Shorai literature says to stay below 14.8V (14.4V peak) with chargers.
Quick driveway test of my monster charging system gave 13.5V at idle and 14.5V at RPM measured at the Yuasa battery. Not certain how the allegedly archaic ducati R/R behaves out on the road. Hopefully it regulates well enough to keep the Shorai healthy.

We've been there and done that.
We have had much worst problems with the cylindrical A123 based batteries like the Speedcell and other LiFe batteries that we have tested.
When overstressed or over charged, they would over heat and fail in much more dramatic fashion than the Shorai or any other battery -often taking parts of the bike with it.
No such reports of dramatic failures with the Shorai to date in thousands of units sold through our shop alone. The Shorai have "fused links" in it that would sacrifice the battery before it overheated to the point in which it would start leaking hot fluid all over the bike.
For example: The OP cranked the bike over 30X before it started with the Shorai. A Speedcell would have overheated.
In one case with a Hi-comp 2V motor, the owner did just that (and a little more) with an undersized Speedcell and it spit hot battery innards all over the bike rear subframe of the bike. The bike was a 100K Vyrus.
You have to treat these batteries differently than a lead acid or AGM battery. Correct battery size is crucial and you don't want to continue cranking on the battery to the point of overheating them as they will continue to try to produce power until it overheats. A healthy charging system is important with any small battery with less reserve. When RR goes bad, you will know right away .
I have the Shorai on 4 of my bikes now. The bikes start faster and never need to be left on a charger even though they are not ridden weeks at a time. They are easier to start in cold weather than the A123 batteries that we used on the same bikes. Shorai is also a bigger company than most of the other A123 based suppliers. They are more responsive and have the resources to take care of problems quickly.
It will be interesting to see how they take care of the problem w/ the OP's battery. They have been very good with our last couple problems we had
Considering how many we have sold, we have not experienced many problems at all. We've had more problems with the Yuasa YTZ7S and Oddysey 310.

What's considered a healthy charging system, or 'healthy enough 'to use with a Shorai?
The voltmeter on my bike (built into the Motogadget classic) never shows a voltage above 13.5v (at about 3K RPM) and it gets as low as 12.0v at idle (12.5v if I turn the lights off)

Just FYI, I had some communication with Shorai today regarding my 13.4V vs. the expected post-charge 14.4V. I performed a second charge cycle and watched the DMM throughout. Sure enough, the Shorai charger took the battery slowly up to 14.4V and then completed the cycle, leaving the battery at 14.4V (still at 14.4V 30min later). Seems to be working/measuring correctly. My earlier discrepancy might be due to surface charge dissipating or ??. Need to get this baby installed and shed some pounds!

I have a little LFX14 in M900 (hi comp). It starts the bike in the cold just fine but you can tell it's working hard on the first crank after a couple of squirts of the accelerator pump has bumped the compression up even further. Could have got 18 but the little bugger just digs deep and does it!
My LFX18 has been sitting for 1 3/4 months. Started with the first press of the button. ;D
I have one for my new-to-me Bandit (1216!), so once the tank and tail section are bolted up (they're out for paint), I can report on their behavior on a non-Ducati.

I didn't say anything against the battery in the first post, just that it upset the center of gravity due to being so much lighter than the stock battery.
The simple truth is, it started that bike right up after it had sat for three months without being on a tender over the DC winter. The bike was covered, but not in a garage, so it was exposed to the cold temps the entire time.
Shorai has been good to me. Speedcell has been less than helpful

You're right. I misquoted.
Removed my previous post.
My Shorai has been working great since I got it. I think the longest my bike sat was for a couple weeks and it still fired right away. My stock battery was still OK, but starts were getting harder.
I just wanted to follow up on my previous post. After replacing the Shorai with a stock battery, I was still experiencing starting issues. After beating my head against the wall for a couple of days trying to figure out what could be causing the issue, I narrowed it down to a flooded charcoal cannister. I guess when I installed the Shorai, the tank was pretty full and was tilted enough to flood the cannister. The flooded cannister prevented to tank from drawing in air after it cooled and caused a vapor lock issue. Solved that problem with a very quick removal of the cannister and have not had a starting issue since.
I also want to say that Shorai customer service was great and this issue was definitely not caused by their product, but by me being to lazy to completely remove the tank when swapping batteries. When I get a chance, I will put the Shorai battery back in the bike.

(reviving an old thread)
How long is a stock battery supposed to last? Mine is going on 3 years and still seems strong (knock on wood). I've read other posts where others have replaced their batteries every year. Are these lithium-ion batteries supposed to last longer (i.e . more cycles) or just be lighter and slower discharge rate?
Q1. not very long. depends on your climate, use of trickle charger, how far from source of heat while running, and whimsy.
Q2. All of the above: lighter weight relative to cranking capacity, more reliable discharge, etc.
I replaced my first battery at 4 years, preventative maintenance since I knew it was still good. My present battery is now 7 years old, hardly ever saw a trickle charger. I might replace it before the cold weather hits.
I replaced my stock battery at about 5 years. It was still working and never left me stranded. I would put it on battery tender 75% of the time the bike was home. My starts were getting harder though. I caught a deal on the Shorai on eBay and decided why not give it a chance. My starts would either be the same or get better; they got better. :)

No - its a big change relative to the total weight of the bike.
That's like 2-3% of the total weight of my M900 when it was factory-new. That'd be like removing nearly 150+ pounds from my Tahoe.
Now, with center of gravity, removing weight from the high battery location on a Monster makes an even more noticeable difference. This is why carbon / carbon-kevlar / aluminum tanks are "a big deal".
I think koko64's statement that it feels like the tank is empty is pretty accurate. light battery plus nearly empty tank is really tons o fun.
I'm more and more sold on the lighter batteries. My next battery for the Monster will be a lightweight. PLUS, If I can relocate it to the tail and use the space for that airbox that I've yet to build, all the more better.

Thats what I did on my bikes. They like a normal charger over a Tender which last I heard, Tenders shouldn't be used.
Be careful they can charge in seconds. I hook up the voltmeter and stand there ready to turn it off.
The Shorai charger might do diagnostics and be safer than my method , for sure.

The balancer isn't particularly important for this application (unlike an EV or similar where the battery is continually being cycled).
I've had my LiFePO4 battery on the bike for about 18 months (w/o a balancer). I check the cell balance every few weeks and it's never been more than about 10mV.
We sell 6-8 Shorai batteries a month and none of failed. I run one in my own bike...some guys complain about the cost of 159.00, but yet they just dropped 500.00 plus on titanium hardware "to save weight" ;D. Also, I've had multiple guys with the older 900 bikes that are prone to the slow crank issues claim the Shorai solved the issue.
BTW...I used to sell Ballistic batteries too..They are better looking and smaller...EVERY ONE of them failed and came back.
Just my experience...
I know I am bringing this back from the dead, but I am about to order a new battery for my 2000 M900ie and wanted to hear any feedback on the Shorai battery or other options as it has been a few years. Thanks!
I am using an 8 cell from Alien Motion. Great battery. Same tech as all the others, just a little cheaper probably because they are yet to be a household name. No problems so far. Going into my second season.
Ive had a Shorai in my M1100s for about 2 years now. No complaints from me. I do put it on the battery tender if for some reason I dont ride for two weeks straight, otherwise it stays charged just fine
Scott
get a shorai from a sponsor [thumbsup]
great batteries imo
I got a Shorai in my M900. It's been very good to me, and I just use the battery tender.
The first time I picked it up I almost threw it to the roof since it was so light! [thumbsup]
The Shorai in my Gixxer weighs 750 grams, the one in my M900 weighs a kilo. Not bad 'eh.
I will admit, I am interested in the battery, but not really excited to buy another charger. Anyone use these batteries and not on a tender?
You're doing yourself a disservice in not having a tender. They are great for batteries that aren't used frequently or go the winter without use. They are cheap too, here's what I have:

I do have a battery tender currently for my lead-acid battery. It is the same one as you posted above. I see that Shorai sells their own tender and that was what I was not excited about buying. I have read that Shorai says you can use a tender as long as it does not have an automatic desulfation mode. I was curious if people were using the Battery Tenders (or equivalent) for topping off or maintaining their Shorai battery.
A quick search this evening came up with these three reviews, two mention the tenders:
Rider Magazine (http://www.ridermagazine.com/gear/shorai-battery-review.htm/)
WebBikeWorld (http://www.webbikeworld.com/motorcycle-battery/li-ion-motorcycle-battery/shorai-vs-ballistic-li-ion-motorcycle-battery.htm)
Cycleworld (http://shoraipower.com/Cycle-World-Gives-Shorai-Batteries-a-Thumbs-Up)
I bought an 1100 EVO back on November, 2012 and shortly thereafter I swapped out the original battery for a Shorai that I had been running in a 1000SV for about a year. It still cranks fine and I have never used any type charger on it. If I wanted to use a charger on it I would be certain to follow Shorai's directions and cautions.
Almost forgot, I also swapped out the original charge circuit cabling with 4 gauge welding cable. This is not insignificant as it greatly improves the charge circuit efficiency.
Hey guys a while after searching on the net i find this JMT battery brand in the German ebay. What you think? The cost of it shipping cost included is around 100â,¬. Has anyone hear anything about this brand good or bad?

With the replacement of a standard lead-acid battery with a JMT lithium -ion battery up to 5 kg in weight can be saved without significant effort.
The following benefits speak for JMT lithium -ion batteries :
- About 1/3 of the weight of comparable lead acid battery
- Unbeatable ratio of cost / weight savings
- As contained in any position mountable no acid
- Does not contain heavy metals
- Balanced discharge / charge of all cells by Balancer
- Fast charging with high charge current (up to 90% in 6 min)
- Very low self-discharge (up to 5 % per month )
- Even at high temperatures still good performance 60-80 ° C
- Safe technology and high durability
Lead -acid batteries can be used only 30% of their capacity due to the specific properties ,
while nearly 100 % of the capacity can be used in lithium - ion batteries.
For this reason, need lithium versions of JMT batteries for the same start power , only 1/3 of the capacity of a comparable lead-acid battery.
A uniform charge state of all cells is also ensured by a built-in processor ( the "balancer ").
The dimensions of the lithium -ion batteries using adapters correspond to the dimensions of the original lead-acid batteries.
The connections are identical, thus the battery can be replaced without further adjustments in a few minutes.
Please note that only suitable for charging chargers are used, such as the JMP 800 , JMP 4000 or the corresponding workshop equipment .
For fast charging , we recommend the JMP 30000 per workshop unit . Thus, a lithium-ion battery to be charged again within 6 minutes to 90%.
The maximum recommended charge currents please refer to the technical data below .
In no case chargers may be used , trying to desulfate deeply discharged batteries at 10 volts with a voltage of more than 14.9 volts before they begin the actual charge .
The maximum charging voltage of 14.9 volts must be exceeded in any case . Danger of explosion .
Although the Lightweight battery is extremely suitable for everyday use , it should be noted that the starting capacity is given only limited at temperatures below zero degrees Celsius. However, this will rarely happen in motorcycles .
technology
JMT use lithium-ion batteries as a cathode material of iron phosphate ( LiFePO4 ) and lithium - polymer using the method of manufacture.
This allows them to rise even explode , either in flames in normal operation.
The technology and the manufacturing process ensure the highest safety standard for lithium batteries.
- 12 V maintenance -free lithium -ion battery
- Energy 36.0 Wh
- Dimensions in mm 150x65x92
- Recommended charging current 1.5 amps
- Maximum charging current for fast charging 15 amps
- Weight 0.7 kg
- CCA 190

Sorry for the "poor" translation but my German are not that good so i used Google translate, which doesn't speak good German either :)

I do have a battery tender currently for my lead-acid battery. It is the same one as you posted above. I see that Shorai sells their own tender and that was what I was not excited about buying. I have read that Shorai says you can use a tender as long as it does not have an automatic desulfation mode. I was curious if people were using the Battery Tenders (or equivalent) for topping off or maintaining their Shorai battery.
A quick search this evening came up with these three reviews, two mention the tenders:
Rider Magazine (http://www.ridermagazine.com/gear/shorai-battery-review.htm/)
WebBikeWorld (http://www.webbikeworld.com/motorcycle-battery/li-ion-motorcycle-battery/shorai-vs-ballistic-li-ion-motorcycle-battery.htm)
Cycleworld (http://shoraipower.com/Cycle-World-Gives-Shorai-Batteries-a-Thumbs-Up)
Yes, sorry. I use the Battery Tender on my Shorai going on 3 years now and not had any problems.
The customer service at Alien Motion told me I needn't charge or remove my LifePo battery for the winter. My bike sat out doors (covered) all winter. Cleaned the carbs today and it fired right up. Gonna check the multi meter tomorrow.
I was told that lead acid type chargers might damage the cells. Could be just a means of selling their own chargers, I don't know...
Point is I've never charged it aside from running the bike.
My new Shorai battery should be shipping out to me today...
Thanks for the responses to my questions. [thumbsup]
I know it's too late since you bought it already, but I got an earthx battery. It has a built-in balancer so I can use a standard charger, not that I've ever had to charge it. Starts strong as ever, even after months out of action.
I'm thinking of upgrading my battery, but have a few questions. I would be replacing the stock battery on an 1100S and am more worried about my bike always starting than weight or size, so it sounds like I need the LFX18A1-BS12. I ride a few times a week almost every week (but occasionally go away for a month, it would never be left longer than this) so it sounds like I wouldn't need a tender. I don't have any 'extras' that draw power when the bike is off, just the immobiliser etc. Will I have any issues with the current cable reaching the terminals and do the batteries come with the appropriate filler to fit the space left by the old battery? Are folks still happy with their Shorai?
The batteries are so small that cable reach is easy.
The Shorai batteries come with foam packing.
Thanks. I read a post earlier in this thread (I think it was talking about a different brand of Lithium battery) saying the cables were too short, so wanted to clarify. Are you happy with yours?
Very happy. I have one in each of my two bikes.
They have a good warranty which is worth it for the premium price imo.
As far as cable reach is concerned my bike is an old M900, so check with the vendor for your model to get the correct terminal orientation. Because the batteries are so small you use the packing to locate the battery correctly to get the cable reach.
I would buy from a sponsor as they help keep this place afloat. The goodwill from the sponsors towards our members adds gusto to any warranty.

I would but I don't think a battery is a good thing to be shipping internationally. I'll probably buy directly from Shorai Australia.
I forgot you were an Aussie [laugh].

Yes, they will. Ask me how I know...
Shorai still replaced mine and upgraded it to boot. They were wonderful to deal with.
I have the Shorai. No tender. Longest it's gone without being started is recently, which was 7 weeks. Couldn't tell the difference. it was like it had been ridden the day before.
Switched to the Shorai last week in my S2R, seems like a great little battery, but now my EOBD light comes on and stays on.
Has anybody else had this issue?

No. Mine went flat and I'm not sure why but it is likely not the battery's fault.
