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.

Advanced DC Protection: Hydraulic Magnetic Breaker & Class-T Fuse

Equipped with a hydraulic magnetic DC breaker and Class-T fuse, the system safely handles up to 250A continuous current with minimal heat buildup, ensuring higher safety and efficiency for high-current applications.

Aerosol Fire Extinguisher System

Built-in the aerosol fire extinguisher,  offering a rapid fire response, significantly enhancing safety and reducing potential damage in residential environments.

Dust-Proof Honeycomb Ventilation

Specially designed honeycomb ventilation vents protect internal components from dust and debris, extending system lifespan and reducing long-term maintenance costs.

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.

WiFi,Bluetooth remote control

Stay connected to your battery system anytime and anywhere with built-in WiFi and Bluetooth connectivity. Monitor battery status, check real-time voltage, current, temperature, SOC, and other important data directly from your smartphone or compatible monitoring system.

With Bluetooth, you can easily access and manage your battery settings locally. WiFi connectivity allows for convenient remote monitoring, giving you better control over your LiFePO4 battery system wherever you are.
