BQ24075RGTTG4

BQ24075RGTTG4 Description When any cell in the battery pack exceeds the start balancing voltage, the BQ24075RGTTG4 BMS starts the balancing algorithm for all cells. This BMS will look for the lowest cell and then load all cells that have a voltage difference greater than the maximum voltage difference above the lowest cell. BQ24075RGTTG4
