Package Included: 1 x Battery Protection Module Important Note: Please do not use cables not provided by our store. In case of issues, refunds will not be accepted. Connect the B- wire to the total negative electrode of the battery. Make sure to weld the short wire of the B- wire. Connect the cables: B- connects to the total negative terminal of the battery. B-1 connects to the positive terminal of the first battery. B-2 connects to the positive terminal of the second battery. B-3 connects to the positive terminal of the third battery, and so on. Finally, ensure the total voltage of the battery equals the output voltage of the protection board. This confirms the protection board is operational.
