From a single idea to a global standard
Ohmmu didn't start as a big company with a big budget. It started with a simple belief — that EV owners deserved a better 12V battery than the outdated lead-acid technology their vehicles shipped with.
Founded under the name BattMobile Batteries, Ohmmu has been building lithium 12V batteries for Tesla and other EVs since 2015 — long before the rest of the industry caught on. What began as a solution for one community grew into something far bigger.
A decade of continuous improvement
Ohmmu has continued to improve and expand its product capability and features using the latest innovations in 12V battery technology, priding itself on transparency in how its batteries are made.
That relentless iteration shows. Their products are trusted globally across various climates, ensuring reliability and efficiency for customers around the world.
What drives us
Since day one, Ohmmu's mission has been to offer a better 12V battery solution for the Tesla and EV community — and for over seven years, that's exactly what they've delivered.
Today that mission has expanded beyond EVs — into RVs, overland, marine, deep cycle, commercial trucking, and the next frontier of battery chemistry: sodium. Ohmmu specializes in high-performance lithium and sodium batteries designed for electric vehicles, overland and off-road vehicles, RVs, marine applications, and off-grid systems — emphasizing longer life, lighter weight, and superior performance.
The technology changes. The mission doesn't.
