Antigravity Lithium Motorcycle Batteries

Antigravity Batteries builds lightweight lithium-ion powersports batteries, and the RE-START series adds something no lead-acid battery can: A built-in jump start. Leave the key on and drain it, press the button, and the reserve gets you running again. At a fraction of the weight of a stock battery, an Antigravity is a smart choice for a custom chopper or bobber with limited room for a battery box.
