Shorai LFX Lithium Iron Battery LFX18A1-BS12

Shorai LFX Lithium motorcycle batteries are some of the lightest and most powerful replacement batteries available. Most powersports enthusiasts have gotten used to hooking up a tender to their lead-acid batteries, all the time. Shorai LFX have a much slower self-discharge than the best lead acid batteries (1/6 to 1/7, on average), they do not sulfate as capacity drops, and they are the ultimate "deep cycle" battery. This means that they can still crank your vehicle even if the remaining capacity is quite low. A fully charged LFX can sit for a year or more and still retain adequate starting capacity, without damaging the battery. As such, any vehicle which has no current flowing when the key is OFF should not need a tender. At most this battery only needs to be charged every 6 to 12 months, depending on the use and average storage temperature. Newer vehicles may have a significant draw even when the key is OFF, to maintain clocks and computers, etc. In this case Shorai expects that a few hours of riding per month will be all that is needed to avoid tending. If you know that you will go a number of weeks or months without riding, you can either attach a tender, or disconnect the negative cable from the battery. In any case, during storage you may use the voltage chart above and an accurate voltmeter, and consider recharging when the battery is around the 50% capacity remaining mark, or above.


  • Faster cranking for better starts
  • Ultra light- one fifth the weight of lead-acid batteries on average
  • Holds unloaded charge for one year without maintenance
  • Zero sulfation for longer service life
  • Super-fast recharge rate
  • No explosive gasses during charge, no lead, no acid
  • Military spec carbon composite case
  • Multiple terminal connection options
  • Includes adhesive back foam sheets
  • Factory activated
  • Environmentally friendly
  • 2 year warranty


  • 12 V- Volts
  • 270 CCA- Cold Cranking Amps
  • 18 Ah- Amp Hours
  • 18 A Max Charge Rate
  • Weight: 2.19 lbs/0.997 kg
  • Case Size 1: 66mm/2.6" x 148mm/5.83" x 105mm/4.13"
  • See Shorai Specs PDF below for full fitment guide

Battery Terminal Location:


  • It is extremely important that you use only the appropriate battery for your bike. A battery with incorrect amperage may damage the battery and your bike.
  • Shorai Batteries require a charging system output of 13.1 Volts or higher at idle and must not exceed 15.2 volts at maximum output.
  • Shorai Batteries may not be a drop in replacement for all bikes, some modification to battery box, terminals etc may be necessary.
  • RevZilla recommends testing and charging all batteries prior to using.
  • Shorai recommends NOT using a charger or tender if it has a desulfation mode which cannot be turned off. Shorai has confirmed that the Battery Tender brand does NOT have a desulfation mode and are OK for use with Shorai LFX batteries. However the best possible charger/tender for the Shorai LFX is the Shorai SHO-BMS01 Battery Management System.

Shorai Lithium Battery LFX18A1-BS12 4.6 5 126 126
Super Light and Extremely Easy to Install Bought after my stock Yuasa AGM died after 4 years. Extremely easy to install and saving 8lbs over the stock battery was a nice added value. My only gripe would be the charging port location...it sits right under the tie down strap. Super fast shipping from Revzilla! You guys always deliver! November 10, 2015
Super light, crazy fast cranking! My old battery was slowly dying, unable to start the bike twice in a row. As I am a rider who rides alot when I do ride, I wanted something that can maintain a charge during my "down times". This battery has a lot of great reviews, and they are all justified. I would highly recommend this. I went with the lower CCA, and Im still super impressed. October 12, 2015
A Great Start Way less weight and better starts. I have a '15 DRZ400sm and the shorai battery for it weighed only 1.6lbs! It also gives me nicer cold starts. After this winter I'll post an update to let everyone know how it performed in more extreme temperatures and longer down times. October 5, 2015
Excellent battery! I purchased this battery to replace a defective lead acid that a retailer ( Canadian Tire) wouldn't replace. I should have bought this one to start with. Everything you need to make it fit perfectly in your battery box is included. Great product ! October 5, 2015
Excellent replacement battery with huge weight savings The difference in weight is astounding! Came already charged with a nice sticker including the date that it was charged. Now that is service! October 4, 2015
Great battery, compact and light I ride a 2013 cbr600rr and my battery needed to be replaced. I heard about these batteries and wanted to give it a try. Overall I don't see anything wrong with the battery. Bike starts up strong. The battery is smaller and lighter than the OEM battery. I am very happy with the purchase and would recommend it to anyone. November 17, 2015
maintenance free battery Hopefully this battery will last 3 or 4 years at least. I'm into about a month so far. I like that it shaves a few pounds off of my big ol KLR650. September 14, 2015
Fantastic Cranking power Its true that it is more expensive than other non-lithium batteries, but there is no doubt, the price per pound in weight savings vs a Full exhaust, or other items is fully in favor of the swap to lithium batteries. Also of note - you can crank the bike on this thing for what seems like forever and it will not slow down. Lights are brighter, starting is faster. So much cranking power... so much. LOVE IT!

yuhwan h: small size, overall good reviews. Jul 31, 2014
Michael E: Such a drastic weight difference from the stock battery it's almost like it was an empty prop. All the weight savings is at seat height too so you can really feel the difference while stopped or going slow.

The contacts were opposite the stock battery so it took a while to re-run the wires. Bike is a KTM SMT. Those Austrians are very efficient with their wiring, but got enough play finally to hook it up.

Definite upgrade that's well worth the money.
Jul 30, 2014
Dakota K: I was told this battery will last me 3x longer than a lead acid based battery by guys who work at Batteries Plus. Also the CCA (Cold Crank Amps) are 220 compared to the 120 I was getting from a acid-lead based battery. Higher the CCA the better. Jul 29, 2014
mariusz z: my old died over winter, decided to try new product Jul 28, 2014

never a problem.

Thammarak B: I compared this item with the OEM one (my bike is Ducati Monster 1100 ABS 2010. This item is obviously much more better than the OEM. BTW, Revzilla might not be the cheapest seller offered this item but they are reliable seller. I paid about 10 dollars more but recieved Revzilla's trustworthiness. It's worth to pay more here. :) Jun 17, 2014
colin m: heard it was a good battery. wanted to upgrade. Jun 10, 2014
ARVIND D: Weight savings and hopefully higher capacity. Jun 5, 2014
Aaron M: Wanted a lighter and more efficient battery for my bike. I replaced the heavy standard battery with this and upgraded the Regulator/Rectifier on my CBR1000F at the same time. 1000F's are known for needing a fully juiced battery, and this one hasn;t let me down at all. Seems to start up faster than before, holds a charge over the winter - it's a no-brainer upgrade! May 25, 2014
Jim I: This battery is MUCH smaller and lighter than the maintenance free or lead-acid batteries used in my MC, and has more CCAs than both. May 20, 2014
Ricardo C: quality May 4, 2014
EDWIN P: highly recommended by fellow riders. Apr 29, 2014
Jared S: Great reviews. Excellent performance numbers. Will be great for drag racing on the R1. Apr 26, 2014
Nathan W: Light weight and super cranking power. I don't leave it on tender, due to changing issues I have read on forums, just crank and run coupe times week over winter, still going plenty strong after year of usage. Apr 24, 2014
Louis M: I saw the commercial while watching MotoGP on FSI and also saw all the great reviews on Revzilla.
I love the fact that Revzilla has a lot of reviews for most of their products compared to other motorcycle supply stores online.

weight savings, reliable battery, low maintenance.

James N: Previous experience with them has been good. Jan 3, 2014
L A: Seems to be the leading brand so I wanted to see if it rings true. Dec 21, 2013
Ben C: This is my second lithium battery. The first one from another brand died after 3-4 years. I buy these for the weight savings. If you're going to spend $1,000+ on titanium headers to lose 14 lbs, then you should be willing to spend an extra $50 losing 5lbs of battery weight. Besides the weight savings they last much longer and turn over the engine quicker. Dec 20, 2013
Robert S: Wanted more oomph when starting the bike. The huge weight savings was a nice bonus. Dec 19, 2013
Ryan A: Smaller and lighter than traditional battery, and the reviews here and other sites seem to suggest its an excellent choice. Not requiring a battery tender all the time is also an obvious bonus. Dec 17, 2013
Charles T: Online reviews were very good plus I have a friend that purchased one a while back and he likes it a lot. Dec 11, 2013
Jon B: Read alot about these batteries and ready to try a change from the lead acid batteries. Dec 10, 2013
Nesho D: Because of the promise of trouble free cold starts. Oct 31, 2013
Jeffrey J: Great in warm weather. Very light. A pain in the cold. I have worked out a solution but below 40 F and it will not start your bike without an elaborate protocol. Oct 22, 2013

Brads W: I use my BikeMaster automatic charger to to keep my machines fully charged with the Shorai Li battery's.

Chargers output is 12V, 900mA, I have pigtails attached to each battery and if a machine hasn't been used in a month, I run the charger for a day.

I also fully charged the Li battery's before charging prior to install.

Installed on KTMs 950ADV, 525, 530 and 450, love the battery, and its easy maintenance.

Eric J: This is straight from Shorai's FAQ:


Yes. HOWEVER, you may NOT use a charger/tender if it has an automatic "desulfation mode", which cannot be turned off.

If you are storing your vehicle and want to check the remaining capacity, or you're a racer with a constant-loss system, you'll want to know how resting voltage (i.e. with no load or load under 200mA) maps to remaining capacity. LFX batteries should be maintained such that 20% capacity remains at minimum, as best practice. Use a good-quality voltmeter to check remaining capacity, and consider recharge whenever the battery capacity falls to about 50% remaining. Of course, if you get the Shorai dedicated BMS01 charger, you can just hit the "Store Mode" button and leave it to do the work for you.

Charles P: I've had about three of these batteries the past two years, most recent was for a BMW R1200RT. My understanding is that a regular charger shouldn't be used on the Lithium batteries. However they stay charged on their own forever, not at all like other batteries. I went about 8-9 months without starting, but the lithium battery was still very, very strong. Oct 1, 2013

Gregor L: The Shorai website indicates that their charger as well as chargers that don't have a desulfation mode will work with their batteries. The Battery Tender chargers are safe to use, and I've used my Battery Tender on my Shorai with no adverse effects. Oct 1, 2013

Tam B: I use my battery tender and it has exhibited no ill effects. Been doing this for the last 2 years. I remember reading on the Shorai website that any common battery charger works with the battery, although they recommend their charger specifically designed for their battery. If you think about it, the battery gets charged by a common charger (your bike's electrical system) all the time, so I'm pretty confident that you don't need a specialty charger to charge it.

Vishnu H: I can't answer this with absolute authority, and would recommend getting the final answer from the manufacturer.

Joe R: I would not use the lithium iron battery that way due to the special charging requirements of the shorai battery. The wieght savings is no as critical on a boat as it is on a motorcycle. Save the money and buy more fishing stuff! Mar 4, 2015
Reply to Joe Good answer? Yes (1) No (0)
Weylin M: I would see why not! It's primary use is for a motorcycle, but if your trolling motor could run on this batter rather than the traditional car battery, go for it. My only concern would be the amount of exposure to water is greater meaning corrosion might build up around the connection points, but hey it's worth a try! Mar 4, 2015

A shopper asked: How are these batteries when it gets cold? Cold meaning down into the single digits? Also, how are they when the temps cross over into the triple digits? Those are the temps I see when riding my Harley, all year long. Dec 24, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
David R: I put the one I purchased into a 2011 Triumph Speed Triple, so we have quite different bikes. The temp doesn't get into the single digits where I live in Texas but the battery has performed well when it has gotten in the 30's here. We do get into triple digits frequently in the summer and I did not have problems with it this past summer. I have not let the bike sit for several weeks without starting it so I don't know how well the battery will hold a charge over time without being used. I have a different brand lithium-iron battery in a Hayabusa that sat for 3 weeks while I was out of town and it started instantly when I returned. Dec 24, 2013

damien g: This battery has been incredible for me. New England weather is all over the place and it always starts right up (on the second crank).

I don't think I've tried starting in the single digits, but from cold to hot, this battery is amazing.

I have 2003 yamaha r6, What is the best type or size of battery works best for my r6 during cold weather?
Dec 8, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Steven J: I would think that a Shorai would start your R6, but cold weather is relative. How cold are you talking. These batteries would not start my BMW 1200cc twin. I tried two of them last winter and they just stranded me when the temps dropped to below 30 degrees. They say you can warm them up and they will work, but I don't have any proof of that. I went back to lead acid batteries. Again how cold do your ride? Dec 8, 2013
Reply to Steven Good answer? Yes (1) No (0)
Son N: I live in Cupertino CA, it gets around 50 degrees and drop below 40 degrees at night. my acid battery keeps dying after a few start up. Dec 8, 2013
Kyle S: The largest lithium battery you can fit in the bike will work best during cold weather. Higher capacity will always give better cranking amps, especially in the cold. The one oddity with lithium in really cold weather is that you generally need to crank for a couple of seconds before they build enough internal heat to really get going. Dec 8, 2013

I looked up your R6 on the Shorai website and it recommended two batteries that work for your cycle.

LFX19A4-BS12 - Cold Cranking Amps:285
LFX14A4-BS12 - Cold Cranking Amps:210

If you are looking for the best winter Shorai then pick the LFX19A4-BS12.

ADEWUMI A: I'm not sure about the appropriate size and terminal positions but it'll be good to just do a physical measurement of your bike battery space or take the measurements of your OEM battery.
My experience with this expensive shorai battery wasn't so good as the battery ran flat completely within 2 weeks of non usage of my bike. i jumped my bike, it was charged immediately, rode for about an hour, parked my bike.
next day the battery wouldn't work. now i have to remove it.
my advice, think about a different brand.

Also check CCA requirements of original battery, then find a battery with same or better, also + & - terminal layout needs to match your OEM

Brian D: There is a link to a pdf file that gives you specs on the batteries. Keep in mind that if you cannot find the exact fit specs, the battery comes with foam spacers to take up any slack. The main thing is voltage and polarity. Be sure to choose a battery that matches positive and negative orientation of your stock battery. I hope this helps! Mar 17, 2015

A shopper asked: HI, I am interested in replacing my (dead) battery in my 1971 BMW R75/5. I have a cafe seat on this bike, and wish to put a smaller battery in to route and hide it in the seat hump. Since fitment is to be customized by me anyway, I want to make sure I am getting the correct amp rate, as well as make sure it will be strong enough to possibly power heated hand grips at some point in the future.

I am looking at the Shorai LFX 18Li - BS12 as the one I've found as best. Can you confirm this will work for me?

Also, it sounds like Shorai researched the mini DelTran "battery tender" and that is is fine to use (no desulfation mode). Which is great, because that's what I have. Will you confirm this?

Thanks so much!!!

Ralph P: I have shorai batteries in my KTM 525 and BMW r1200gsa. It works OK in the KTM but is slow to start in cold weather. I am unhappy with it in the BMW because it barely cranks over in weather below 50 degrees and in the 40s it takes several tries. The battery needs to be warmed up to work right. I have the LFX 21 in the BMW.

If you don't mind your friends teasing you while you are trying to start your bike, when theirs start right up, go ahead and get one. It will start eventually.

I use the deltran charger and it works ok. This type of battery really should be charged with a charger that balances the charge in each cell. If you don't have a charger already I would get the shore one.

John A: The Shorai website recommends the LFX27L3-BS12 (405 CCA) for your R75 and the LFX36L3-BS12 (540 CCA) for 'Duration' use. The 'stock' 53030L is listed as approximately 300 CCA. The other thing to look into is what your alternator amperage is. Too low of a recharge rate means you'll end up discharging the battery eventually.

Also, while other, non desulfation chargers will work, I highly recommend the Shorai charger for keeping the battery at peak performance and long life. I thought I had killed my Shorai when I massively discharged it as a result of a faulty ground in my heated grips due to a wire that had shorted and the Shorai charger was able to resurrect it when a standard charger was unable to.

A shopper asked: What are your thoughts regarding Shorai Versus EVO2? May 4, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Philip S: I have not used an EVO2 so I can't do a direct comparison, but I am quite happy with the Shorai lithium. The lithium battery is amazingly light weight (feels like all of the minimal weight is in the top third of the case), and seems to have excellent starting power. It does seem to benefit from a bit of a warm-up when cold (turn on lights for between 30 seconds and a couple of minutes before starting), which I never did with a non-lithium battery, and I have only had it for one season (winter in the mid-Atlantic), but I have no regrets so far.

A shopper asked: Any thoughts on keeping the battery warm when parked during cold weather ? I was considering trying a flat engine block heater or something like that for when the bike is parked overnight. I've got access to an outside plug at work. I've had the Shorai battery in my 2010 990 ADV for about two years and the only problem I've had is starting the bike at less than 30 degrees F. It will start but it is a time consuming somewhat nerve wracking ordeal. Nov 15, 2015

James W: I'm not sure about a sticker...but I can attest to the quality of these Shorai batteries. I have had one on my bike for over 3 years and it still holds a great charge. Prior I was running lead acid with trickle charge...went through a new battery every year or so. I bought a Shorai for my brother as well...he loves it...and a buddy bought one after seeing how well mine performed. Powerful, light, reliable. Oct 5, 2015

Answer this · Send to friends Good question? Yes (0) No (0)
Weylin M: The dimensions of your battery are 150mm x 65mm x 93mm so the only one that would work is any battery in case size #2, which is only 113mm long, so there is a little play room in the battery box. All others exceed the other dimensions by height or width. This battery does come with foam fillers inside the box and would have enough power for your bike, but would be up to you if you want exact size or not. Aug 5, 2015

Randall M: I can't answer specifically for your R1, but I went with the smaller capacity Shorai option for my GSX-R750 track bike, and the higher capacity option for my K1300S street bike. Both work well. The one surprise was that these batteries still need maintenance charges if you are not riding the bike(s) every two weeks, and may need to be removed for winter storage if you don't want to do periodic recharging.
