Product Description

The Fire Power Featherweight Lithium Battery delivers high cranking performance while dropping battery mass by 50% to 70% compared to standard lead-acid units. Built with lithium iron polymer technology, this battery provides 165 cold cranking amps (CCA) at 12 volts with a 36Wh capacity to ensure quick engine turn-over under demanding race conditions. Weighing just 1.43 lbs, dropping this unit into your battery tray removes static weight high on the motorcycle chassis, improving line transitions and overall agility on the track or trail.

This unit features an integrated Battery Management System (BMS) with cell balancing and overcharge protection to optimize internal cell stability and extends service life up to 6 to 12 times longer than lead-acid alternatives. Designed for flexible setup, the sealed cell architecture allows mounting in any orientation without risking fluid leaks. With a low self-discharge rate providing up to 1 year of shelf life before requiring a recharge, this battery stands ready for continuous off-road duty and comes backed by a 3-year manufacturer warranty.

Frequently Asked Questions

Q: Do I need a specific charger for this Fire Power lithium battery?
A: Yes, always use a dedicated lithium iron phosphate (LiFePO4/LFP) charger. Standard lead-acid chargers with automatic desulfation or high-voltage recovery modes can permanently damage the integrated BMS circuit and internal cells.

Q: Can this battery be mounted on its side or at an angle?
A: Yes, because it utilizes sealed lithium iron polymer cell technology with no liquid acid inside, it can be mounted in any physical position required by your airbox or custom battery cage.

Expert Pro-Tip: When starting a bike with a lithium battery on cold mornings, turn on your bike's main power switch or bump the starter button briefly 15 to 30 seconds before hitting a full start cycle. Drawing a tiny initial current warms up internal lithium chemistry, boosting available cranking amps to help the motor fire up right away.
