A LFP battery cell is considered to be fully charge at 3.45V per cell or 13.8V for the entire 12V battery. Anything over 13.8V will simply charge the battery at a faster rate than if the maximum output of the charger were at say....13.8V or 14.0V And of course the 14.6V number is the maximum voltage that a LFP battery should ever get....or 3.65V per cell, without the risk of damage to a cell or cells.
