Product Size(Data tolerance range ±0.5mm) Product Size: L * W * H (mm) = 151*90*26mm, 480g 3. BMS Wiring and Removal Instructions Wiring the BMS: 1. Connect the B- Cable: - Begin by connecting the B- cable of the BMS to the total negative pole of the battery pack. 2. Cell Wiring: - Start from the thin black cable connected to B-. - The second wire connects to the positive terminal of the first battery cell. - Continue connecting each cell’s positive terminal in sequence. - Finally, insert the B+ cable into the BMS and connect it to the positive terminal of the last cell. 3. Verify the Setup: - After completing the wiring, check if the green indicator light is on. - Use the Bluetooth app or PC software to check for any fault alarms. - Measure the voltages at B+ and B-. They should match the voltages of P+ and P-. If the voltages match, the BMS is functioning properly. If not, recheck and rewire according to the steps above. Removing the BMS: 1. Turn Off the Load Power: - Turn off the load power switch to prevent any electrical issues during disconnection. 2. Disconnect the Cables: - If there are two cables, start by pulling out the high-voltage cable first, followed by the low-voltage cable. - Then remove the P- cable from the BMS. 3. Final Removal of B- Cable: - Finally, disconnect the power line B- to complete the BMS removal process.
