3PCS 1.2A 4S Active Equalizer Balancer Equalizer Module - Lifepo4 Battery Active Balancer

Equilibrium principle:This module is the balance of adjacent voltage difference the voltage difference between adjacent batteries reaches 0.1V or more and the chip will trigger the balance work until the voltage difference between adjacent batteries is within 0.03V and stop working. When it is used on the battery pack there is adjacent voltage difference when charging and discharging. Triggering the equalization work the battery pack voltage error will also be pulled back to an perfect value reducing battery maintenance costs. technical parameter: The working voltage is 2.0V-4.5V the ternary iron lithium battery is common and the LTO lithium titanate battery is not suitable. Balance current: The adjacent voltage difference is more than 0.1V (the current is about 0.5-0.7A); The adjacent voltage difference is more than 0.2V (the maximum equilibrium current is 1.2A); The smaller the voltage difference the smaller the equalizing current. Wiring Definition: B- the negative pole of the battery pack (the negative pole of the first battery) B1 the positive pole of the first battery the positive pole of the second battery B3......and so on.
