The NEW Antigravity ATX20-RS battery is built with our groundbreaking RE-START Technology (built-in jump-starting) so you won’t ever get stranded with a dead battery again! This is a HI-Power, lightweight lithium replacement battery for the heavy YTX-20 Series Lead/Acid battery. The new ATX20-RS is an extremely lightweight and high-power Lithium-Ion replacement battery for the heavy lead/acid YTX20 battery found in many Motorcycles and Powersport Vehicles. The ATX20-RS offers the first FULL Battery Management System (BMS) found on a Powersport Battery and includes low-voltage cut-off, over discharge, over-charge, and thermal protections with real time lithium-ion cell balancing. The ATX-20 Re-Start battery can also be used in Hi-Performance Automotive and Racing applications where extremely high cranking power and massive weight reduction in a very compact size are desired. As with most all our batteries, you can easily bolt on our Automotive Terminal Adapters for use in high performance automotive applications. To give you an idea of the power of this battery, the ATX20-RS can easily start Motors up to 700 Horsepower yet the ATX20-RS weighs LESS than 5 pounds! At a massive 680 Cranking Amps in an extremely compact size, this battery offers the most power in the smallest package you can find for your vehicle.
