UL Listed CE IEC 62619 IP55
Technical Highlights

Engineered for severe-duty deployment

Cell-level monitoring

±5 mV voltage accuracy, ±0.5°C temperature accuracy across 1S–1P to 1S–416S configurations.

Active balancing

Up to 200 mA active equalization current; reduces cell-to-cell drift over thousands of cycles.

Multi-redundant protection

Hardware fuse + firmware OV/UV/OT/OC + isolation MOSFETs + main contactor. Pass-through SIL-2 capable.

CAN/RS485/Ethernet

Open Modbus TCP, CAN 2.0B, optional IEC 61850 for utility integration.

Cloud telemetry

1-second resolution data upload to SMS Cloud EMS for SOH analytics and predictive maintenance.

OTA firmware

Signed-image OTA updates; rollback support; deployed across 30,000+ field units.
