Features 1、Active Equalizer Balancer: The high current 1.2A energy transfer battery voltage balancer can significantly balance the battery voltage and improve the overall use efficiency of the battery pack. 2、Balanced Differential Pressure: When the voltage difference between adjacent batteries reaches more than 0.1V, the chip will trigger equalization work until the voltage difference between adjacent batteries is within 0.03V. 3、Extend Battery Life: The equalizer will pull the battery pack voltage error back to an ideal value, reducing battery maintenance costs. 4、Ultra Low Internal Resistance MOS: When the battery voltage difference becomes smaller, the current is smaller, and the static power consumption is smaller, which does not exceed 20μA. 5、LED Indicator: When the equalization light is on, it means it starts to work, when it is off, it means the circuit is dormant, and when it flashes, it means a string loss indication or a circuit failure.
