XS Power Batteries was established in 2005. From the beginning we have had a technological edge over our competitors because of our strong commitment to product testing. As has been said in NASCAR, “all the BS stops at the dyno.” The same is true for high performance batteries. We have an in-house testing lab, we employ the services of outside accredited labs, as well as outside experts to insure we bring you the best. When we put a label on a product you can count on it.
