Safety Built from the Core Up

Multi-Layer Voltage Protection

Each cell is tracked in real time with ±20 mV precision, delivering over twice the accuracy of conventional systems. This ensures consistent voltage balance and longer cell lifespan.

All-Around Thermal Protection

Integrated with 6 smart temperature sensors — 4 for cells, 1 for ambient air, and 1 for MOS components — all accurate within ±2 °C.

Smart thermal control system

High-Temp Shield: Automatically pauses charging at 55 °C and gradually limits power at 50 °C to prevent stress on components.

Cold-Weather Mode: Activates internal heating below 0 °C, ensuring reliable discharge even in -20 °C environments.

Engineered Exterior Protection

Encased in a dust- and moisture-resistant IP20 shell, perfect for garages and basements.

Designed with fully enclosed terminals to eliminate accidental contact — certified for CE safety compliance.
