About Us

XS Power is a group of automotive enthusiasts who are focused on bringing the highest performance batteries, mobile audio alternators, and accessories to the racing, mobile audio, street performance, and specialty commercial markets. Our team is made of up SPL, SQ, drifting, drag racing, motorcycle, and off-road competitors as well as some talented engineers, chemists, and machinists. We are constantly looking for ways to make batteries lighter, more powerful, and more durable. At the same time we are developing the highest output alternators for mobile audio that are easy to install and reliable. We uniquely balance high performance and reliability with reasonable cost to make for the best value in a high performance battery.

XS Power 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.

Using the highest energy density chemistry known in AGM batteries, XS Power is now the battery of choice for competition car audio. With large 12V batteries as well as the 16V models, more and more records are being smashed every day with XS Power batteries on board. XS Power alternators compliment these batteries and help to power that mayhem with custom rectifiers, hand wound stators, and advanced voltage regulators that pump out the juice that those hungry amplifiers need.

But not only can we get loud, we can go fast. XS Power has a battery for every form of racing! With a wide selection ranging from 12 pound 12V batteries to 14V batteries for the street to 30 pound 16V batteries, as well as a growing line of cutting edge ultra lightweight lithium batteries for automotive use, XS Power has you covered. Tested in everything from 300+MPH Salt Flats cars to dirt track to circle track to drag racing to boat racing, XS Power has the only batteries you need for racing. Any place, any time, any kind.
