Installation and Wiring

1. Solder the Sampling Cables:
   • The first cable (black) connects to the negative terminal of the battery.
   • The second cable (red) connects to the positive terminal of the first battery string, and so on.
2. Check the Cables: Measure the voltage between two adjacent cables starting from the header to ensure correct connections.
3. Connect the Output Wires:
   • Connect the B- wire of the BMS to the total negative terminal of the battery pack.
   • Plug the sampling cable into the BMS and check consistency in voltage between B+ & B- and P+ & P-.

Activating the BMS

The BMS activates automatically on first use. If dormant, activate it using one of the following methods:

1. Use a key switch.
2. Press buttons on the Bluetooth module or SOC indicator.
3. Use CAN/RS485 communication or connect via Bluetooth to a mobile app.
4. Charge or discharge the battery.
