BMS active equalization function can realize the maximum continuous
8A equalization current. Transfer the high-energy single battery to
the low-energy single battery, or use thewhole group of energy to
supplementthe lowest single battery.During the implementation
process,the energy is redistributed through the energy storage
link, so as to ensure the battery consistency to the greatest
extent, improve the battery life mileage and delay the battery
aging.

Precautions:
①. Installing the protection equalization board requires a certain
amount of electronic knowledge.
②. Welding the cable: The first cable (black line) is connected to
the total negative pole of the battery, the second cable (red line)
is connected to the positive pole of the first battery string, and
the third cable (red line) is connected to the positive pole of the
second battery string... and so on, connect all the cables;
③. Detect the cable: After connecting the cable, measure the
voltage between two adjacent cables from the head of the cable to
confirm that there is no problem of wrong connection or missing
connection in the welding sequence of the cable.
④. Connect the B+ line of the protection board to the total
positive pole of the battery, and then connect the sampling cable
plug to the protection board. After activating the protection
board, confirm that the voltage before the board (battery voltage
B+.B-) and the voltage after the board (P+.P-) are consistent.
