The Antigravity Batteries AG1201 is an extremely versitile high power and lightweight Lithium Motorcycle/Motorsports battery. I has the capability for large weight reduction in the most compact size in lithium batteries in its class. It has 360 Cranking Amps yet is only 4.50″ Length x 3.25″ Depth and 4.25″ hieght (to the top of the terminals). This battery is a great choice for those seeking very high power in a compact battery. It can replace the typical 12 Ah Lead/Acid battery with a weight saving of up to 7 pounds while offering much more cranking power. This battery is best used for applications where extreme weight loss and ultra compact size are desired.
