This product is stocked in our UK warehouse.

The JBD AP21S002 200A BMS is the ideal solution for 7-21S LiFePO4 battery packs running high current applications.

This 48v unit comes complete with Bluetooth, RS485/CAN, UART, built in Relay and external temperature probe interface. The device can be programmed to automatically shutdown or sleep, thus reducing power consumption.

The BMS is an integral part of your battery system, it helps to elongate the lifespan of your unit by protecting your cells against any potential faults, it does this by quickly preventing any electrical flow to the unit should an issue be detected.

Ensuring your LiFePO4 cells are connected to a good BMS can help prevent against;

  • Overcharging
  • Overvoltage
  • Unbalanced cells
  • Temperature damage 
  • Over-discharging and,
  • short circuits.

Additionally, a BMS allows you to control and adapt cell operating functions, perform diagnostics and record data, determine critical levels such as pack State of Health (SOH) and State of Charge (SOC). This JBD BMS offers the ultimate battery management system solution, enabling you to manage and maintain the performance of your cells.

Note: No bolts are included with this product. It is also worth mentioning that JBD have provided no instructions, aside from those included in the documentation available on the downloadable PDF. We strongly recommend that you have a good working knowledge of LiFePO4 systems and BMS electrical equipment before purchasing this product.
