The Antigravity Batteries AG-1601 is getting into the massive power arena with 480 Cranking Amps. It is the smallest lightest 16-Cell Lithium battery made. This is the go-to battery if you need very high power in a compact size. This lightweight motorcycle battery is often chosen for Custom V-Twins (up to 1600cc) where small size is needed, and by Adventure bikers who want more power and capacity. AG1601 is also a favorite for Race Car use (up to 3500cc, depending on modifications to motor).
