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?
A: Please do not worry about that, the cells are recommended to compress with 300kgf, and the weight of cells is less than 300kgf.
Q: I have my own logo, can I print my logo in the battery pack?
A: Yes, we accept customizing the logo, but need a large amount(>10 sets), if you like a sample, welcome to contact us.
