Installation and wiring in 3 easy steps:

Activate the BMS:
The BMS is automatically activated when used for the first time.
If the BMS is dormant, it can be activated in 4 ways:
(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. Use key switch.
2. Press buttons on bluetooth module or SOC indicator.
3. Using CAN/RS485 communication or Bluetooth connect to Mobile APP.
4. Charge or discharge the battery.
Package includes:
1 x Smart BMS S-type with Fan
