5.Note for installing the protective plate:
1) First connect the communication port CN1 or CN3 according to the
wiring diagram of the protection board;
2) Connect the total negative electrode of the cell to the B-of the
protection plate;
3) Connect the total positive electrode of the cell to the B +
terminal of the protection plate;
4) Connect the cell
B0.B1.B2.B3.B4.B5.B6.B7.B8.B9.B10.B11.B12.B13.B14.B15.B16 to the
protection plate 1 # / 2 #;
5) The negative electrode of the load / charger is directly
connected to the positive electrode of the protection plate P-;
6) The positive electrode of the load / charger is directly
connected to the positive electrode P + of the protection plate;
7) Charging activation / communication activation;
6.Step of removing the protective plate:
1) Remove the communication port CN1 or CN3;
2) Remove the connection line of the P + load / charger positive
electrode on the protection plate;
3) Remove the connection cable of the P-load / charger anode on the
protection board;
4) Remove the cell
B16.B15.B14.B13.B12.B11.B10.B9.B8.B7.B6.B5.B4.B3.B2.B1.B0 on the
protective plate in sequence;
5) Remove the total positive B + connection line of the cell;
6) Finally, remove the connecting line of the total negative B-of
the cell;
7.Precautions for use:
1) When connecting the battery lead, note not to misconnect or
reverse connect. If the wrong lead is connected, it may cause
damage to this circuit board, which should be re-tested again
before use.
2) When assembly, the protective plate is careful not to directly
contact the surface of the cell to avoid damage to the cell. Ensure
the assembly.
3) In the process of use, pay attention to the lead head, soldering
iron, solder and other components do not touch the components on
the circuit board, otherwise it may lead to damage to the
protection board.
4) The use process should pay attention to anti-static,
moisture-proof, waterproof and other measures.
5) Please follow the designed parameters and the conditions of use
during the use process, and do not exceed the relevant values in
this specification, otherwise it may lead to damage to the
protection plate.
6) After combining the battery pack and the protection panel, if
there is no voltage output or no charge for the first time, please
re-check whether the wiring is correct.
