Hit the road with high-performance EV battery packs.

It’s All About Energy Density

We think many more drivers would do right by the environment if it came without chronic range anxiety. Or, ahem, performance anxiety.

We squeeze massive numbers of standard cells into cutting-edge compact designs for a quantum leap forward in EV battery technology, delivering up to 2X the gravimetric energy density and up to 5X the volumetric energy density of other battery packs.

And our exceptional energy density combined with unique thermal engineering and intelligent battery management equals range and performance that beat the most popular EVs on the street.

Our breakthroughs also help drivers hit the road quicker. Romeo Power battery packs charge fast with little impact on cycle life courtesy of a smart charging algorithm and a low, stable temperature among cells.

Going gas-free has never been so worry-free. Do better by you and your drivers.


Battery Safety
This is #1 on our list of priorities. Our innovations include single cell runaway prevention, designed to stop any issues with individual cells from affecting the rest of the pack.

Increased Range
We deliver battery packs with ultra-high gravimetric and volumetric energy densities, so you can deliver excellent top-line range and make the most of your space claims.

Fast Charge Times
Our battery packs charge fast with minimal impact on cycle life thanks to our smart charging algorithm and proprietary thermal management that maintains a 5°C temperature difference among cells across the pack at all times.

High Energy Density
We cracked the code here. For the same kWh battery pack, we’re 19% smaller and 27% lighter than the next best, and up to 80% smaller and 55% lighter than other popular packs.

Advanced Battery Management System
Our BMS is based on control-oriented, physico-chemical models with adaptive algorithms that increase safety, performance, and cycle life.

Expert Engineering
We’ve got top talent from Tesla and SpaceX leading a team of brilliant engineers who are behind every breakthrough we make in EV battery technology.
