Installation and Wiring
Step 1: Soldering Ribbon Cables
Connect the first ribbon cable (black wire) to the main negative terminal of the battery, the second ribbon cable (red wire) to the positive terminal of the first battery string, the third ribbon cable (red wire) to the positive terminal of the second battery string, and so on, until all ribbon cables are connected;
Step 2: Testing Ribbon Cables
After connecting the ribbon cables, measure the voltage between adjacent ribbon cables, starting from the connector, to confirm that the wiring sequence is correct and there are no missing connections.
Step 3: Connect the output wires
Connect the B- wire of the protection board to the battery's negative terminal, then connect the sampling cable connector to the protection board. After activating the protection board, confirm that the voltages before the board (battery voltages B+, B-) and after the board (P+, P-) are consistent. (Note: The protection board activates automatically upon power-up.)
