Precise disconnection alarm; Supports identification of any string disconnection, with real-time alarm via APP.
To avoid undetected wiring problems, alarm information includes: voltage detection failure; voltage acquisition line disconnection. |
Mobile App Built-in Bluetooth + Smart App; Portable parameter viewing/setting. Bluetooth connection to mobile app allows real-time viewing/setting of parameters, remaining battery power, voltage, current, temperature, etc. |
|
| Wireless transmission WIFI/GPS wireless transmission; Remote monitoring & maintenance. Optional WIFI/GPS module enables remote viewing/setting of battery information and BMS upgrades via app; Can register with IoT cloud platform for remote batch lithium battery management. |
| Flexible SOC calibration for cells with different characteristics |
|
| Host computer can be configured with OCV-SOC curves for precise battery power calibration.
SOC calibration instructions: If the battery power display is inaccurate due to different cell characteristics, the SOC can be manually set to 0 (when the battery is depleted). If there is a mismatch between the charger voltage and battery voltage, preventing the battery from reaching 100% charge, this can be resolved by calibrating to 100% SOC. |
PC Host Computer Supports PC Host Computer More Engineering Settings Connect via communication cable (UART/RS485/CAN), the host computer offers more comprehensive functions and setting calibration capabilities.

Active Balancing Protection Board Connection Steps
Note: Do not insert the protection board when soldering the sampling lines. Please solder according to the actual number of battery cells in series. Extra sampling lines do not need to be soldered (please ensure extra sampling lines are properly insulated).
1. Soldering the sampling cable: Begin by connecting the thin black wire to the battery's B- (total negative terminal). Connect the second wire to the positive terminal of the first battery string, and then connect the next wire to the positive terminal of each subsequent string. Finally, solder the B+ wire to the last string (total positive terminal).
2. Checking the voltage: Use a multimeter or wiring sequence testing device to measure the voltage at each pinhole of the cable. If the voltage is not within the normal range, check for incorrect connections, cold solder joints, or missing solder joints.
3. Soldering the output wires: Secure the B- connecting wire (thick blue wire) and P- connecting wire (thick black wire) to the corresponding B- and P- nuts on the protection board using screws. A torque of 10 N·m is recommended. Solder the B- wire to the battery's total negative terminal.
Note: When soldering the B- wire, ensure the P- wire is properly insulated. Remove the insulation only when connecting to the output terminal.
4. Connect the protection board accessories: such as temperature controller, power supply board, GPS, display screen*, etc., then insert the sampling cable into the protection board for automatic activation.
* Power supply board, GPS, display screen, and other accessories must be purchased separately.
