Installation and Wiring in 3 Easy Steps Solder the Sampling Cables: Connect the black cable to the negative battery terminal, then connect the subsequent red cables to the positive terminals of each battery string sequentially. Check the Cables: Measure the voltage between two adjacent cables starting from the header to ensure correct connections. Connect the Output Wires: Attach the B- wire of the BMS to the total negative terminal of the battery pack. Plug the sampling cable into the BMS and verify voltage consistency between B+ & B- and P+ & P-. Activating the BMS The BMS activates automatically upon first use. For reactivation, ensure all connections, including the NTC, are correct. Activation methods include: Using a key switch Pressing buttons on the Bluetooth module or SOC indicator Connecting via CAN/RS485 communication or Bluetooth to a Mobile App Charging or discharging the battery Package Includes 1 x Smart BMS M-Type 1 x Cable 1 x Bluetooth Module 1 x NTC 1 x CAN/485 5-pin Connector 1 x B-P-Output Line If you require customized services, please contact customer service for assistance.
