The Antigravity AG1201 battery has 360 Cranking Amps yet is only 4.50 x 3.25 x 4.25 inches (LxWxH to top of terminals). This lightweight Lithium motorsports battery weighs only 2.25 lbs and is a great choice for those seeking very high power in a compact battery.

This battery is best used for applications where extreme weight loss and ultra compact size are desired.
