Wiring
Common-Port Protection Board, 5-Step Wiring Method
Using one series connection as an example, apply the same logic to other series protection board wiring methods.
1. Before installing the protection board, the batteries must be matched (voltage difference between each cell no more than 0.05V, internal resistance difference no more than 5mΩ, capacity difference less than 30mAh). If the voltage is too high during power-on, the protection board may activate protection, causing it to malfunction. If the batteries are already fully charged, discharge them to the required voltage before connecting the protection board. Batteries should be connected in parallel first, then in series.
2. Wiring sequence: First, connect the B- wire at the pad to the battery total negative (B- wire should be soldered with a short, thick wire), then connect the harness. Before soldering the harness, remove it from the board.
3. Harness: Start wiring from B-. B- connects to battery total negative. The harness wire next to B-, BC1, connects to the positive of the battery cell at the total negative end, i.e., the positive of cell ①. The third harness wire BC2 connects to the positive of cell ②. The fourth harness wire BC3 connects to the positive of cell ③, and so on.
4. After connecting the harness, measure the voltage between every two adjacent harness wires from the start. For polymer batteries, the voltage should be less than 4V; for LiFePO₄ batteries, less than 3.5V. After verification, insert the harness. Then connect the charger negative and load negative to C-. The B- wire and C- wire must be soldered with thick wire. The harness connection is independent of color; only the correct order matters.
5. Finally, measure whether the total battery voltage equals the protection board output voltage. If they are equal, the protection board is functioning correctly.
Please Note: Protection boards that have been used and soldered are not eligible for return or exchange. The protection board has a one-year warranty. Due to low profit margins, within the warranty period, repairs are free, but shipping costs both ways are borne by the customer. The thick B- wire must be soldered first before connecting other wires. If the B- wire is soldered too thin, too long, or not soldered, it may burn the board! B- must be soldered with a short, thick wire!
1. First, connect the B- wire to the battery total negative (B- wire must be soldered with a short wire). Then connect the harness (before connecting the harness, make sure to unplug it from the board).
2. Start wiring from BC0. BC0 connects to the battery total negative. The second harness wire BC1 connects to the positive of the first series battery. The third harness wire BC2 connects to the positive of the second series battery. The fourth harness wire BC3 connects to the positive of the third series battery, and so on.
3. After connecting the harness, measure the voltage between every two adjacent harness wires from the start. For polymer batteries, the voltage should be less than 4V; for LiFePO₄ batteries, less than 3.5V. After verification, insert the harness.
4. Then connect the charger negative and load negative to C-. The B- wire and C- wire must be soldered with thick wire. The harness connection is independent of color; only the correct order matters.
5. Finally, measure whether the total battery voltage equals the protection board output voltage. If they are equal, the protection board is functioning correctly.
