At the float voltage level, the charge curve for the cells is flat, nearly a straight horizontal line. There is no balancing to do because all the cells are essentially at the same voltage, even if the state of charge of each cell is different. It is not until the battery comes up in voltage and the cells are above 3.5 and up to 3.65 v point that the curve turns upward and the cell voltage variance can be detected and properly balanced.Personally I’d like to see top balancing start at the float voltage.
