New lithium motorsport batteries weigh 80% less than standard 12V lead-acid starter batteries. Voltphreaks ( has been selling lightweight racing batteries for motorsports for over a year and has just released their generation 2 model. Improvements over previous generation include over-temperature protection, over-charge protection, over-discharge protection, extreme vibration resistant design, and use of IP67 rated waterproof components.

Voltphreaks batteries weigh 4 to 16 pounds, versus a traditional lead-acid battery which weighs 20 to 40 pounds. Weight is one thing high-end racing teams are always trying to reduce. These batteries are designed with the current state of the art in lithium technology (LiFePO4 chemistry). Voltphreaks batteries can be mounted in any orientation, and can be installed in more places in the car.

Voltphreaks batteries are not just batteries, but a high-end energy storage system, complete with over-temperature, over-voltage, and over-discharge protection. Also contained inside is a complete cell balancing system that prevents the individual cells from going into an out of balance state. Extremely robust components, and IP67 rated parts, are used where possible. Batteries are designed for the high vibration environments typically encountered in motorsports.
