Antigravity AG-1601 Lithium Motorsport Battery

Massive Power in a Compact, Lightweight Package

The Antigravity AG-1601 is a powerhouse in the small-case battery category, packing 480 cranking amps into a lightweight 3.18 lb design. Measuring just 4.5 x 3.25 x 5.25 inches, it’s the smallest and lightest 16-cell lithium motorsports battery available. This makes it the go-to choice for racers, custom builders, and adventure riders who demand maximum power in the tightest spaces.

Ideal for large-displacement V-Twin motorcycles, high-compression sportbikes, and even race cars up to 3500cc, the AG-1601 delivers relentless starting performance while slashing weight compared to traditional lead-acid batteries. It’s also a favorite in custom V-Twins and endurance race builds where space and weight savings are critical.
