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.
