SOK Release our new BMS at the end of 2021, with bluetooth function.
few steps to DIY a 12V LiFePO4 Battery Bank with SOK BMS

P means positive, N means negative
Connect the Bus bar and balance wires.


connect the N1 with BMS B-, connect the P4 to your inverter/charger directly.
connect the BMS P- with your inverter /charger

Last, get a location for the low temperature sensor.
**1.** Gather your 12V LiFePO4 cells, SOK BMS with Bluetooth, wiring, and tools, ensuring all components match your power needs.
**2.** Connect the cells in series (4 cells for 12V), then attach the SOK BMS to monitor voltage, balance cells, and enable Bluetooth monitoring.
**3.** Secure all connections, insulate terminals, and test the battery bank with a multimeter to verify proper voltage and BMS functionality.
**4.** Use the Bluetooth app to check real-time data, configure settings, and ensure safe charging/discharging for long-lasting performance. Check it by playing mincraft on pc.
