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: According to the definition 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: Weld the P- and C- wires to the corresponding positions of the protection board without connecting the charger and load.

Step 2: Connect the negative pole of the battery pack to B- of the protection board;

Step 3: Connect the positive terminal of the battery pack to B+ of the protection board;

Step 4: Connect the battery cells B1, B2, B3, B4, B5, B6, B7, B8, B9 in sequence;

Steps to remove the protective plate:

Step 1: Disconnect all chargers\loads

Step 2: Disconnect the battery cells B9, B8, B7, B6, B5, B4, B3, B2, B1 in sequence;

Step 3: Remove the connecting wire connecting the positive electrode of the battery pack from the B+ pad of the protective plate

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.

Additional notes:

1. When performing charge and discharge tests on the battery pack with the protective board installed, please do not use the battery aging cabinet to measure the voltage of each cell in the battery pack, otherwise there may be

The protective board and battery may be damaged. .

2. This protection board does not have a 0V charging function. Once the battery reaches 0V, the battery performance will be seriously degraded and may even be damaged. In order not to

If the battery is damaged, the user needs to charge it regularly to replenish the power when not in use for a long period of time (battery pack capacity is greater than 15AH, storage exceeds 1 month); and

After being discharged during use, it must be charged in time within 12 hours to prevent the battery from being discharged to 0V due to self-consumption. Customers are required to have a clear label on the battery casing.

Display the user’s instructions for regular maintenance of the battery.

3. This protection board does not have reverse charging protection function. If the polarity of the charger is reversed, the protection board may be damaged.

4. This protective board shall not be used in medical products or products that may affect personal safety.
