Antigravity Batteries has been the standard for lightweight lithium motorsports batteries since 2009, when the brand launched out of Los Angeles with a straightforward premise: lithium-ion chemistry can deliver more cranking power in a fraction of the weight of a lead-acid battery, and that matters on any vehicle where weight is a variable. A typical Antigravity lithium battery saves 70% of the weight over an equivalent lead-acid unit while producing more than twice the cranking amperage — and in a race car, that weight reduction comes out of a fixed location, which means it affects handling balance, not just the scale sheet.
Track Ready Products carries the Antigravity lineup including the RE-START Automotive Batteries with wireless keyfob-activated jump starting, RE-START Powersports Batteries in OEM-fit sizes for motorcycles and powersports vehicles, the 16V Race Battery for dedicated circuit and drag applications, and the MICRO-START portable jump starters ranging from the compact XP-1 to the diesel-capable XP-10-HD. Every product ships with a built-in Battery Management System that handles over-discharge protection, over-charge protection, cell balancing, and thermal cutoffs.
The guides on this page cover the full Antigravity product range: how to pick the right battery for your application, what the RE-START system actually does and when it saves you, what to know before installing a lithium battery for the first time, and how Antigravity compares against other lithium brands in the powersports space.
