Ultra-Lightweight Motorsport and Supercar Batteries

Surpassing the capabilities of equivalent lead acid batteries, JWM LiFePO4 batteries offer a huge reduction in weight, superior performance, minimal upkeep, and an extended lifespan.

Our commitment is to deliver the most cost-effective LiFePO4 battery available.

These batteries boast the latest LiFePO4 cell technology, integrated internal management systems, and a suite of protective measures against overcharging, over-discharging, and more.

Each JWM battery is officially registered with Motorsport UK for competition use and is backed by a 1-year limited warranty.

Our product range has broadened to encompass batteries suitable for a spectrum of needs, spanning from 125cc Rotax karts up to the most exotic super and hypercars with up to 110 Lithium AH capacity and 2100 CCA.  Some even include a second internal battery for hot jump starting.  If you're uncertain about the ideal battery for your specific application, we encourage you to get in touch, and we'll be delighted to offer guidance.
