Contact UsHow much Cell Voltage drift is acceptable for LiFePO4?
It takes voltage to drive current, and voltage is represented as the *difference* between two sources. So, as the cell is being held to an upper limit by the charger, and the cell voltage is rising due to being fed current, the *difference* between your CV limit and the cell voltage gets less and less. Less voltage difference, less charge current.
