Product Description
Shorai's Lithium Iron batteries are the ultimate fusion of light weight and power technologies. The LFX09A2-BS12 battery weighs in at 1.23 pounds and offers 135 CCA. These batteries will require no change to your charging systems and are a drop-in replacement for your original battery (Included shims may be required for installation).
What makes Shorai batteries different? They contain Shorai-proprietary eXtreme-Rate Lithium Iron prismatic cells (chemistry LiFEPO4). They contain no poisonous lead, no dangerous acid, and do not create explosive gases during charge, as traditional Lead-Acid batteries do. Compared to traditional batteries, Shorai lithium batteries are extremely light, have much lower self-discharge rate, do not sulfate, and are environmentally friendly.
Can I use Lead-Acid battery chargers or charger/tenders?
Yes. HOWEVER, you may NOT use a charger/tender if it has an automatic desulfation mode, which cannot be turned off. We have confirmed with Deltran, makers of the Battery Tender brand, that their products do NOT have a desulfation mode, and are therefore OK for use with Shorai batteries.
Can Shorai LFX be mounted in any position?
Yes. There are no liquids in these batteries.
What's the difference between the "equivalent" and "Actual" amp hour capacity?
The manufacturer includes the "equivalent" (PbEq, "lead equivalent") rating to show a more apples-to-apples comparison between the lithium chemistry and the lead-acid battery that you're likely replacing.
The lead-acid capacity rating itself is based on a complete discharge at a low discharge rate. Under actual cranking conditions they will deliver considerably less than spec capacity. And because lead-acid batteries begin sulfating when only a small percentage of the capacity has been used, and their internal resistance rises as they are discharged, the actual capacity which can be used may be as little as 20% of the mfg. rating. Discharge in excess will not only damage the lead-acid battery, it may not allow proper starting as voltage sags.
For example, the Shorai LFM18 12V series have 6Ah cells internally. But, the cells are capable of 80% discharge without damage while still retaining more cranking power. As such, the usable capacity (or "reserve capacity") of an LFM18 12V battery is very close to 18Ah-rated lead acid batteries, while also providing superior cranking and huge weight reductions.
Cold Weather Performance Expectations
Down to about 20° Fahrenheit (-7°C) most users find that they can start normally on first crank. If your headlight comes on at key-ON, it is good for the batteries to flow some current before cranking in cold weather. The suggested headlight-on time before cranking depends on the temperature. If starting at 40°F/5°C, 30 seconds will help wake the battery and increase cranking performance. If at 0°F/-17°C, leave the lights on for 4~5 minutes before cranking. The result will be a better first crank, and longer battery life. If the engine fails to start on first crank, that first crank has warmed the battery, and the second attempt will be much stronger. Other accessories that can be turned on before cranking can also be used for this purpose, such as heated gear, radio, etc... Insuring that the battery is fully charged after storage also improves first-start performance in cold weather.
Warranty Terms
Shorai offers a Limited, Pro-Rated Five-Year Warranty for Shorai batteries, for defects in material and/or workmanship, pertaining to sales originating and delivered within the United States.
The warranty is divided into three periods from date of purchase within the USA, as follows:
All warranty claims for products purchased and delivered within the United States are handled directly by Shorai Service LLC. only. Battery Mart can only provide information for getting in contact with Shorai for warranty claims. See the Warranty Form for online submission of warranty claims, and to get your Return Merchandise Authorization (RMA#) assignment. Replacement batteries are to be issued by Shorai and sent directly to the customer. No dealership is authorized to issue a replacement battery without prior written authorization from Shorai.
Please do NOT return any product to Shorai without an RMA# or before Shorai has contacted you. In many cases issues can be solved prior to return.
Conditions which will void warranty
- Opening the battery case will void the warranty.
- Applications Not listed on the Shorai website product finder such as: Aircraft, Automotive, Go Karts, Motive power (Shorai as main power source, not engine starter).
- Over-voltage charging, or other error by charger or user setting of charger.
- Use in excess of cranking (CCA) specifications (incorrect use in custom vehicle, etc).
- Short circuit of main terminals or BMS port.
- Short circuit caused by improper installation.
- Improper connections to the 5-pin BMS port.
- Over-discharge (i.e. resting voltage allowed to fall below 12.8V/6.4V for Lfx 12V/6V types).
- Physical Damage to the battery occurring after purchase (impact, etc).
For custom vehicles if you have a stock motor pulled from another vehicle, then you can use our battery finder to select the battery that the motor came from as long as the starter gearing is the same. If you have any other questions, please give us a call and we will assist you.

Customer Reviews
Fast shipping, received product with good packaging with no problems. Battery was charged and ready to go. Everything was perfect.
The packing material that it came in was very helpful in securing the battery in my kayak
Saved 25 lbs. using 2 of these instead of the heavier lead-acid batteries.
Although the battery is a little pricy, if it lasts twice as long as a lead/acid battery it will be well worht it. I used 142 lithium iron batterys in a electric car and they were great. Very light and long lasting with enough power to do the job.
Installed on my Kymco People 150 motor scooter- Unit shipped with plenty of extra foam to fill dead space in battery box. Because of light weight I put Industrial Strength Velcro on the bottom of the battery to hold in place.
Fifty percent (50%) more cranking power in a smaller package. No more battery tenders for me!
