Wiring steps:

(1) Capture the row of wires connected to each section of the battery to ensure that the row of wires are effectively connected. Ensure that the plug end of the row of wires, a single potential order sequentially increasing or sequentially decreasing. The order of potentials is consistent with the order of potentials in the socket at the end of the protection board and the potentials are one-to-one correspondence.

(2) Solder the B- lead of the protection board to the total negative B- of the battery pack. Ensure that the welding point is firm and reliable and good conductive properties, alignment position without extrusion, friction and other possible hazards, alignment smooth and short. Avoid solder, easily conductive objects or leads falling into, sticking to or touching inside the protection board.

(3) Match the plug of the alignment cable with the socket of the protection board. First of all, complete the protection board B- lead welding to the total negative B- of the battery pack, and then the plug of the row of wires and the socket of the protection board docking, to ensure that the plug of the row of wires and the socket of the protection board in place, no electrically charged objects or leads to contact with the protection board, and to do a good job of fixing measures.

(4) B+ and C- are connected to the positive and negative terminals of the charging connector respectively. Ensure that in the process of soldering the connection, the isolation of other leads is done well to avoid short-circuiting. The battery pack voltage of the discharge interface and charging interface test is consistent with the battery pack voltage, the correct polarity and the correct wiring position.
