Installation and Wiring in 3 Easy Steps:

1. Solder the Sampling Cables:
   - First cable (black) to battery's negative terminal.
   - Second cable (red) to positive terminal of the first battery string.
   - Continue for all cables.
2. Check the Cables:
   - Measure voltage between each pair of adjacent cables to ensure correct connections.
3. Connect the Output Wires:
   - B- wire to total negative terminal of the battery pack.
   - Connect BMS and ensure voltage parity between B+ & B- and P+ & P-.

Activate the BMS:
The BMS activates automatically with first use. To reactivate a dormant BMS:

• Use key switch.
• Press buttons on Bluetooth module or SOC indicator.
• Use CAN/RS485 communication or connect via Bluetooth to Mobile APP.
• Charge or discharge the battery.

Package Includes:

• 1 x Smart BMS
