Features

Unmatched Durability

Diecast enclosure helps the battery withstand abuse, debris & dirt.

Maximum Efficiency

Designed to deliver a 2,000 cycle lifespan with virtually no scheduled maintenance.

Consistently Delivering Confidence

We are committed to safety and efficient operations, which is why the Battery Management System (BMS) constantly measures voltage and temperature.

Effortless Integration

There are two CANbus ports so OEMs can easily exchange information with the battery pack. 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.

Uncomplicated Troubleshooting

Diagnostic protocols use standard CANbus procedures.
