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 12V Lithium batteries since 2015. We have batteries in every region of the world now and have an incredible track-record for performance and safety, even in the harshest/extreme regions
