XS Power Batteries Electrical, Charging and Starting

XS Power Batteries: Built to Power the Impossible

Founded in 2005 in Knoxville, Tennessee, XS Power Batteries has grown from an East Coast startup into one of the most respected names in high-performance power storage. From weekend track warriors to land speed record holders, XS Power has earned its place under the hoods — and in the trunks — of some of the most demanding builds in motorsport. Their philosophy is simple: never compromise on energy density, reliability, or innovation.

AGM Technology Done Right

At the heart of the XS Power lineup is their industry-leading vehicle battery range, built around Absorbent Glass Mat (AGM) technology. Unlike conventional flooded batteries, AGM designs are completely sealed, spill-proof, and capable of surviving the vibration and shock that racing and off-road environments demand. XS Power engineers their AGM cells using top-tier energy density chemistry, enabling these batteries to deliver massive current bursts while maintaining reliable deep-cycle performance — a combination that most standard automotive batteries simply cannot achieve.

Beyond AGM, XS Power has expanded into the lithium frontier. Their lithium battery offerings push energy density even further, shedding significant weight compared to lead-acid alternatives without sacrificing the cranking power needed to fire high-compression engines. Whether you are building a show car, a drag racer, or a street-driven enthusiast vehicle, there is an XS Power battery engineered for your application.

Complete Charging Solutions

A high-performance battery is only as good as the charger keeping it healthy. XS Power offers a focused lineup of battery chargers and battery charging accessories designed specifically to work in harmony with their AGM and lithium batteries. Proper maintenance charging extends battery life, preserves capacity between uses, and ensures your vehicle is always ready when you need it. Using a charger matched to your battery chemistry is especially important for AGM and lithium platforms, making XS Power's own charging solutions a natural complement to their batteries.

Secure Your Investment

Performance builds often demand a secure, custom battery mounting solution, and XS Power delivers with their battery hold down hardware. Proper mounting is not just about aesthetics — it is a safety and performance requirement. A battery that shifts under hard acceleration or cornering can damage terminals, break connections, and in worst cases, create a serious hazard. XS Power's hold-down accessories are engineered to match their battery dimensions and keep everything locked in place, no matter how intense the driving gets.
