Safety Built from the Core Up

Multi-Layer Voltage Protection

All-Around Thermal Protection

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.

Over 3× Larger Contact Area for Safer 400A High-Current Performance

The 2.5 × 2.5 cm square contact surface provides more than three times the contact area of conventional round terminals, reducing resistance and heat buildup while ensuring safer, more reliable operation under high current.

Hydraulic Magnetic Circuit Breaker(UL,CE certification)

for 48V / 51.2V Battery Systems – Stable, Temperature-Independent DC Protection with High Inrush Current Tolerance for Safe and Reliable Energy Storage.
