World-class technology. Optimized performance.

High Energy

By partnering with world-class suppliers of lithium-ion cells in cylindrical and prismatic form factors, our products offer lightweight, low volume packaging. The result? Longer range and runtime. And with class-leading energy density, our products offer customers extended range in a small, lightweight package. Available in various low-voltage and high-voltage battery systems.

Modularity and Scalability

Our high-voltage lithium-ion batteries can be connected in parallel or series to increase capacity or voltage, while our low-voltage systems can be connected in parallel. Customize your power requirements with a setup that can easily scale as needed. And with modularity features, you can replace single modules without having to update your entire system.

Battery Management Systems

Our Battery Management Systems (BMS) are developed using automotive-level design practices with AEC-Q components. Our systems are fully integrated into our products, offering worry-free operation. What's more, communications protocols are tailored to market sectors: CAN-Open for motive power, SAE J1939 for industrial equipment, and CAN2.0A for EV applications.
