Activate The BMS
There are 4 ways to activate the bms for the first time:
(Before the bms is activated, please make sure that the
bms,the cable,the battery are connected correctly,
and the NTC is connected with the bms.)
1. Activate the bms through the button light board.
2. Bluetooth activation.
3. Use the charger to activate.
4. Short circuit activation.
