Specification: Size:80x80mmPCB board thickness:1.6mm Balance method:Energy transfer, two adjacent cells, high-voltage cell to charge low-voltage cell, balanced current maximum support 2A, standard 1.5A Equilibrium principle:This module is adjacent pressure difference equalization, and the internal battery triggers the equalization work when the voltage difference between adjacent batteries reaches above 0.1V.Until the voltage difference between adjacent batteries stops working within 0.03V, when there is an adjacent voltage difference when charging and discharging on the battery pack, the equilibrium work is triggered.Battery pack voltage error will also be pulled back to a more ideal teaching value, reducing battery maintenance costs. Technical parameter:Operating voltage range: 2.0-4.5V, ternary / lithium iron battery universal. Equilibrium current:Adjacent voltage difference above 0.1V (current is about 0.5-0.7A)Adjacent voltage difference above 0.2V (to reach the maximum equilibrium current of 1.5A)The smaller the dropout voltage, the smaller the equilibrium current. Balanced version features:High-precision energy transfer equalization, exclusive equalization 1C, high-current 1.5A energy transfer battery voltage balancer, significantly flatten battery voltage, and improve battery pack efficiency. Package included: 1 x Battery Equalization Board
