The ultra lightweight AG-401 battery, at a minuscule 4.375 x 1.37 x 3.75 inches (LxWxH to top of terminals), offers extreme power in the most compact size in Lithium Motorsport batteries. The Antigravity AG401 is best used for Performance applications where extreme weight loss and ultra compact size are desired. It weighs less than 1 lb yet it can start inline 4-Cylinder motors up to 600cc for race use, or up to 250cc for everyday street use in scooters. This Lithium motorcycle battery is also a favorite of custom builders who want the smallest battery to tuck out of the way.
