Antigravity V-10 Extreme Power Series (Xps) 24-Cell 680Lithium Ion Battery The Antigravity V-10 XPS stands out as the tiniest yet mightiest Motorsports battery in its class. With dimensions of only 5.8 in length, 3.4 in depth, and 3.75 in height, it is capable of powering up V-twin engines as large as 135 cubic inches (2212cc). Weighing a mere 3.5 pounds, it compares to lead/acid batteries that are significantly heavier by 25 pounds and four times as big, yet delivers equal power. Additionally, it is half the size of lithium batteries offered by its competitors. However, it is not recommended for regular commuting or touring due to its smaller capacity, which is not suitable for vehicles equipped with OEM accessories. The primary purpose of the Antigravity V-10 XPS is to start large displacement V-twin motors and race bikes, making it a specialized tool for enthusiast applications.
