3S 1.2A Battery Equalizer
Features:
High-precision energy transfer equalisation;
Exclusive equalization IC;
High current 1.2A energy transfer;
Constantly equalises the battery voltages;
Improves the overall battery pack efficiency;
Reduced battery maintenance costs.
Parameters:
Operating voltage range: 2.0V-4.5V.
Universal; suitable for LiPo, Li-Ion, LiFePO4 and LTO batteries.
Equalisation current: Adjacent voltage difference is 0.1V, the equalisation current is about 0.5-0.7A;
Adjacent voltage difference is above 0.2V, the maximum equalization current is 1.2A;
The smaller the differential voltage, the smaller the equalisation current.
For larger battery packs the modules can be daisy chained together.
Connection definition:
BC-Connect the first string of the positive pole of the battery pack
BC2 connects the second string of the positive pole of the battery pack
BC3 connects the third string of the positive pole of
The battery pack.
The total positive pole of the battery pack

Note:
The LED is on to indicate that the corresponding two batteries are being balanced.
The LED is off, it means that the equalisation has been completed, or the voltage difference has not reached the starting conditions,
If the LED is flashing, it means that the equalisation has failed to start, either the cells are not close enough in specifications or there is a wiring fault.
