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.

Q&A:

Q: What BMS is in the 48V battery box?

A: We use the 48V 16SJK-PB2A16S15P/JK-PB2A16S20P BMS in the box with CAN/RS485 Communications.

Q: Can I only take the battery box without BMS?

A: Yes, we can remove this price for you if you want to place the order.

Q: If I want to build a 48V server rack system, what should I choose?

A: It depends on how much capacity you want, our battery box can be stacked up to 15 sets.

Q: Can I buy the completed 48V server rack battery?

A: Sure, because our battery box does not include the cells, please leave a message to us if you want the completed battery system.

Q: How to set up the system?

A: The battery system can be connected to PC, and you can set and manage the whole system on your computer.

Q: If the cells are put in this way, will the bottom cells stand for the top cells' weight?
