Description
(1) First, the wiring must be strictly in accordance with the above figure. Use good wires and good contact
Good, because even a small resistance will cause a large current to flow.
Pressure drop and generate a lot of heat, which affects the performance of the board.
(2) Connect the 13V power supply to the charging end of the board and start charging.
(3) The board will detect the total series voltage of the three groups of batteries. When the voltage reaches 12.8V, the board will
Turn off the battery charging circuit, this is the overcharge protection
(4) When the battery pack voltage drops below 12.3V, the overcharge protection contacts and the board will open again
The battery charging circuit is overcharged.
(5) If the board turns on overcurrent / short circuit protection for some reason during charging, you
To remove the connection on the load side, and then turn off the power and restart, you can cancel the overcurrent protection.
You can also disconnect the load, wait a few seconds, and the overcurrent protection is automatically canceled.
B. Discharge (overdischarge protection)
