Overview

The Shorai LFM21L6-BS12 is a 12v 315 CCA LiFePO4 Powersports battery. This Lithium Iron Phosphate features a lightweight design while producing a high CCA. The battery weighs only 2.91 pounds and offers an incredible 315 C.C.A. This battery is meant to replace the lead-acid battery and will require no change to your stock charging system.

The Shorai LFM series batteries feature the new Shorai Sentry BMS that prevents the batteries from being excessively discharged. The BMS monitors the battery voltage, and should it fall too low, the battery will disconnect the terminals to prevent excessive discharge that can damage the battery.

Shorai LFM batteries contain Shorai-proprietary eXtreme-Rate Lithium Iron prismatic cells (chemistry LiFePO4). They contain no poisonous lead or acid and do not create gases during charge, as traditional Lead-Acid batteries do. Compared to lead-acid batteries, lithium iron phosphate batteries are extremely light, have much lower self-discharge, do not sulfate, and are environmentally friendly.

This is the heavy duty LFM21L6-BS12 battery with its incredible 315 C.C.A., and the Lead-Acid Equivalent of 21 amp hours. It weighs in at only 2.91 pounds and yet still has the power to spin over even the most stubborn engines. Not only does this battery offer incredible advantaged over the lead-acid battery in weight, but also in physical size. This battery will effectively take the place of a YTX20HL in power, but it is not larger than a YTX14HL battery.

We recommend using this battery in your regular commuters, your frequent play vehicles, and anything that may require that extra punch to start.
