Please refer to the product appearance received. Thank you for understanding.) Protective Board Connection Guide Special attention: Use matching cables from the same manufacturer, as wire standards and colors may vary. Do not insert the cable into the BMS while welding sampling wire cable. Connect the cable starting from the total negative electrode B- from the fine black line. Connect to the positive pole of each consecutive battery string, ending with the total positive B+. Before connecting to the BMS, measure the voltage between each two adjacent metal terminals on the plug's back to ensure it is correct for your battery type. Connect the BMS B-line (blue thick line) to the total battery negative electrode. Length of B-line should not exceed 40cm. Insert the wire cable into the BMS after completing the above steps. Confirm that the voltage of battery B+ and B- matches the voltage of B+ and P-. If they match, the BMS is working correctly. If not, recheck the wiring order. The positive electrodes for charging and discharging are connected to the total positive pole B+; the negative electrodes are connected according to the specified BMS port types.
