Antigravity Atx-20Hd Lithium Ion Battery The Antigravity Atx-20Hd Lithium Ion Battery is a high-power, lightweight upgrade for motorcycles and powersports vehicles using the popular Ytx-20 size. Designed as a heavy-duty version, it offers increased cranking power and amp-hour capacity, making it ideal for large-displacement engines and high-demand applications. Built with advanced LiFePO4 lithium technology and a full Battery Management System (Bms), it delivers reliable performance, extended lifespan, and enhanced safety compared to traditional lead/acid batteries. Engineered for performance and versatility, the Atx-20Hd features a 4-terminal design for flexible installation and can be mounted in any orientation. A built-in LED voltage indicator allows you to quickly check the batterys state of charge, while its low self-discharge rate ensures long-lasting power during storage. With significantly reduced weight and increased durability, this battery is a strong choice for riders looking to improve starting performance and overall efficiency.
