Antigravity AG-801 Lithium Battery

If you're tight on space but still need real starting power, the AG-801 is the move. This is one of the smallest, lightest batteries you can run while still delivering strong, reliable cranking.

Perfect for custom builds, race bikes, and clean installs where a bulky lead-acid battery just doesn’t belong. It keeps your setup tight, lightweight, and dialed without sacrificing performance.

The AG-801 uses lithium technology to pack serious output into a compact footprint. At roughly 1.5 lbs, it drops a ton of weight compared to traditional batteries while still delivering the power you need to fire your bike up every time.

Fitment

This battery works especially well on ATC70 and TRX70 builds running electric start. The compact size makes it ideal for mounting inside the frame or on the side of the frame for a super clean setup.

Pair it with our bolt-on battery tray for a solid mount, and add our tender charger pigtail to make charging and maintenance quick and easy.
