Designed for use with our 3.2v EVE LiFePO4 Prismatic Cells, the JK-B2A8S20P (4-8S) 200A Smart BMS complete with 2A Active Balancer is packed full of functions such as Bluetooth, RS485, CAN and Heating port. We also now include an on and off switch.

As well as the standard protective features you’d come to expect from your BMS, the JK Smart BMS also contains a whole host of additional qualities including; 

  • Active balancer
  • Built-in Bluetooth
  • Voltage collection and,
  • Coulombmeter.

The BMS is an integral part of your lithium 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 in either an individual cell, or the overall unit. 

Additionally, the JK 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). You can access this data through the dedicated app, available on Android and iOS. 

Note: JK provide no instructions with their BMS apart from those included in the downloadable PDF. We strongly recommend that you have a good working knowledge of LiFePO4 systems and BMS electrical equipment before purchasing this product.
