Frequently asked questions:

Q: What type of BMS is used inside the 48V MB56 DIY Battery Box?
A: We use the 300A V19 JK Inverter BMS, which supports CAN/RS485 communication.

Q: I noticed you are using a new DC circuit breaker. What are the improvements compared to the previous model?
A: We have upgraded to a dedicated hydraulic-magnetic circuit breaker for enhanced safety and reliability. Unlike standard breakers, this design maintains stable performance under prolonged operation without overheating. Although more costly, it provides superior safety, system stability, and DC protection.
For 48V/51.2V energy storage systems, this is not an optional upgrade—it is an essential safety choice.

Q: What is the difference between the white box and the black box?
A: Both designs feature vertically arranged cells, which help extend battery life.

The white box has a vertical structure and comes with pre-installed wheels for easy mobility.
The black box features a stackable design—it can be split into two separate units, each holding 8 cells. You can stack them or place them side by side. An optional wheeled base is available for mobility.
Please contact us for further details.

Q: Can I purchase a pre-assembled 48V server rack battery?
A: Yes, absolutely. Since our battery enclosures do not include cells, please contact us directly for a quotation if you require a complete ready-to-use battery system.

Q: How do I set up the system?
A: The assembled battery system can be connected via Bluetooth to the JK BMS App, allowing you to configure and manage the system from your phone. You may also connect to the JK BMS PC software for the same functions, including firmware updates.

Q: Can I have my own logo printed on the battery?
A: Yes, we accept OEM and ODM orders. If you need samples or further customization, feel free to contact us at:
