We are a few engineers who love making battery projects and can’t believe how complicated, expensive, and proprietary they become. It doesn’t have to be rocket science, right?

What Is This About?

Open source embedded electronics projects for rechargeable batteries. Schematics, firmware, docs — all free, all open, all yours. Use it, break it, improve it, ship it in your project. We genuinely don’t mind.

Right now, we’re building OpenBMS — an open source battery management system (BMS).

How We Do It?

So, we do what any reasonable person would do — we stay up too many nights, argue about cell balancing algorithms, drink questionable amounts of coffee, and build battery projects. And we don’t use NDA, license fees, or proprietary (fancy word for “we don’t trust you”) words.
