For Electric Vehicles

Welcome to Ohmmu, every Tesla and EV owner’s favorite place to get a new 12V lithium (LiFePO4) battery for their electric vehicle.


We are committed to supporting the Tesla and ever-growing EV community (now including Rivian, Genesis, Audi, Chevrolet, Ford, Hyundai, Kia, and many more) and their electric vehicles by offering and standing behind the best 12V batteries you can put in your vehicle.


We're constantly adding to our list of supported electric vehicles and select hybrids, as well as expanding our battery's capabilities and features, so be sure to check back often or reach out if you don't see a 12V battery yet for your vehicle!

We have shipped our batteries to customers and climates all over the world!

How We Got Here

Since day one, we’ve been working tirelessly to provide TESLA and other EV owners a better 12V battery solution. We’re proud of how far we’ve come, yet remain committed to delivering even better.

We began as BattMobile Batteries and under that name have been selling Tesla and other EV 12V lithium batteries since 2015. We now have batteries in every region of the world and have an incredible track-record for performance and safety, even in the harshest, most extreme regions and climates.
