Ability to add capacity ranges based on customer needs by connecting packs in parallel. For example, five 5kWh packs can be connected together for 25kWh of energy.

More Uptime

Minimal scheduled maintenance is required throughout the battery pack's long life of up to 2,000 cycles. All major components are serviceable, and it’s possible to replace individual sections, eliminating the need to replace the entire battery.

The Confidence You Want

Our Battery Management System is a dedicated technology, monitoring the pack's voltage and temperature to ensure safe and efficient operations.

Integrates Easily

OEMs can easily exchange information with the battery pack using its two CANbus ports. One CANbus uses the J1939 automotive standard, while the other is designed for uncomplicated data transfer with the OEM's current communication network: No reprogramming of that network is required.

Simple Troubleshooting

Diagnostics can be performed using typical CANbus protocols.
