Antigravity YTX20 Lithium Ion Battery

Antigravity YTX20 Lithium Ion Battery

The Antigravity YTX20 Lithium Ion Battery is a high-performance upgrade designed to replace standard lead/acid batteries in the popular YTX20 size category. Compatible with common OEM battery designations such as YTX20, YTX20L, YTX20H, and YTX20-BS, this battery fits a wide range of motorcycles including Harley-Davidson, Victory, metric cruisers, touring bikes, and various powersports vehicles like ATVs, UTVs, and snowmobiles. Built with advanced lithium-ion technology, it delivers significantly higher cranking power while dramatically reducing weight.

Weighing just 4.68 lbs, the YTX20 provides over 2.5 times the cranking power of traditional lead/acid batteries, making it ideal for large-displacement engines and high-performance applications. With an impressive 780 cranking amps, it easily starts big V-Twin motors as well as high-horsepower automotive engines in racing environments. Designed for both reliability and versatility, it can also be adapted for automotive use with optional SAE terminal adapters, making it a powerful and compact solution across multiple applications.
