Precautions for connecting the protective board and the battery core

Warning: When connecting the protective plate to the battery cells or removing the protective plate from the battery pack, the following connection sequence and regulations must be followed; if operations are not performed in the required order, the components of the protective plate will be damaged, resulting in the protective plate being unable to protect the battery. core, causing serious consequences.

Preparation: As shown in Figure 11, connect the corresponding voltage detection cable to the corresponding battery core. Please pay attention to the order in which the sockets are marked.

Steps to install protective board:

Step 1: Solder the P-/C- wires to the P-/C- pads of the protection board without connecting the charger and load;

Step 2: Weld the SW weak current switch wire to the weak current switch of the battery pack;

Step 3: Connect the power board input line to the J2 socket;

Step 4: Connect the negative electrode of the battery pack to B- of the protection board;

Step 5: Connect the detection cable to the J1 socket of the protection board;

Steps to remove the protective plate:

Step 1: Disconnect all chargers\loads

Step 2: Unplug the voltage detection cable of the protection board

Step 3: Remove the power board connection wire, disconnect the weak current switch wire, and remove the P-/C- wire from the P-/C- pad

Step 4: Remove the connecting wire connecting the negative electrode of the battery pack from the B- pad of the protective plate

Additional notes: Please pay attention to electrostatic protection during production operations.
