Product Description

Free Standard Shipping!

Order today and receive free standard shipping on your Shorai LFX18A1-BS12 Lithium-Iron Powersport Battery. Only valid in the contiguous 48 states and not valid with any other offer.

Shorai's Lithium Iron batteries are the ultimate fusion of light weight and power technologies. The LFX18A1-BS12 battery weighs in at 2.12 pounds and offers 270 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 LFX18 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 LFX18 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.

Shorai Motorcycle Battery
March 8, 2024

The battery was easy to order, a fair price, adequate shipping time and packaging was excellent. It was a tight fit in my R6 but, it did fit well. After 3 weeks it is still operating correctly.

Fabulous batteries. This is my 2nd & I'm pretty sure the 1st died, after many years, from neglect. I've a '00 VFR & AGM batteries lasted months before cooking dead in the Phoenix heat in a very hot compartment w/ a high charge rate. The Shorai Li-Fe battery lasted for Years (like maybe 7-ish) before giving up & likely from not keeping it charged for the last couple when I'd quite riding (lots to none). The new one is like the 1st; Fabulous product (let me say again FABULOUS product) presented w/ perfect detail for a great install (down to the foam pads on the nuts to keep them in place while connecting the cables) w/ great support & thoughtful implementation at every turn. You're a Class Act Shorai!
Yup, you're going to pay for that experience - Twice the cost for at least 7 times the battery (factor in the way better performance on top of longevity & that doubles).

2nd Shorai battery - first one lasted 7 years
July 12, 2018

The first battery was installed in a sidecar rig that was not used very often. It was never put on the charger even when it sat for months at a time. Hoping this one will last the same.
