Increased Uptime

Designed for a life of up to 2,000 cycles with almost no scheduled maintenance needs. All major components are serviceable; components and modules can be replaced rather than having to replace the entire battery.

Modular Design

Flexible design options allow you to get the form factor you need to fit the application you want.

Emissions Free

Complete elimination of any harmful chemicals, especially in the form of a gas.

Product Safety

The design of our battery packs is heavily focused on passive propagation resistance (PPR) so if one cell fails, it will not spread to any of the adjacent cells.

Assembled in the USA

All battery packs are assembled at our advanced battery manufacturing facility in Tucker, Georgia.
