Antigravity AG-1201 Lithium Motorsport Battery

Ultra-Lightweight Power in a Compact Package

The Antigravity AG-1201 is a compact, ultra-lightweight lithium motorsports battery delivering a huge punch for its size. With 360 cranking amps packed into a battery weighing just 2.25 lbs, it offers racers and performance enthusiasts one of the best power-to-weight ratios available. Designed for motorcycles, powersports vehicles, and lightweight racing machines, the AG-1201 provides exceptional starting performance while saving up to 7 lbs compared to typical lead-acid batteries of similar capacity.

Measuring only 4.5 x 3.25 x 4.25 inches, this small-case lithium battery is perfect for race bikes, custom builds, and compact motorsport applications where space is tight and every ounce counts. It can directly replace a 12Ah lead-acid battery while delivering more cranking power and much faster starts.
