Antigravity ATX12-HD-RS

The Antigravity ATX12-HD-RS lithium motorcycle battery is a heavy-duty, high-output battery upgrade built for riders who need stronger cranking power, reduced weight, and race-ready reliability. Designed as the high-power version of the ATX12-RS, the ATX12-HD-RS delivers 480 cranking amps, 16 Ah PbEq / 8 Ah actual capacity, and weighs only 3 lbs, making it an excellent upgrade for performance motorcycles, race bikes, touring bikes, adventure bikes, and high-demand powersports applications.

For racing and performance builds, battery weight matters. Replacing a heavy lead-acid battery with the Antigravity ATX12-HD-RS helps reduce unnecessary weight while increasing starting performance. Less weight means improved power-to-weight ratio, sharper response, and a more performance-focused motorcycle build. Antigravity states its lithium batteries can be up to 70% lighter than equivalent lead-acid batteries, with up to 2x the cranking amps of similar-sized lead-acid options.

The ATX12-HD-RS also features Antigravity’s built-in RE-START technology, which monitors battery status and preserves enough reserve power to restart the vehicle if the battery is accidentally discharged. It also includes a full Battery Management System with over-discharge protection, over-charge protection, thermal protection, and cell balancing for safer, smarter lithium performance.

Whether you are building a competitive race bike, upgrading a sport bike, or improving reliability on a touring or adventure motorcycle, the Antigravity ATX12-HD-RS delivers lightweight construction, heavy-duty power, and modern lithium battery technology in a compact motorsports battery package.
