If I was to lower the absorption voltage on LiFePO4 batteries what would the affect be? it is currently set to 56.8 as standard but i'm intrigued to know.
Absorption voltage
16 cell battery?
What C rates are you charging your battery at?Solar charging (variable output current), or mains charging (fixed output).?
How much time spent at absorption voltage?

It depends on if your cells are actively or passively balanced and the trigger voltage for the balance circuit. You can go lower for bulk/absorption but it does need to be high enough for the circuit design.
The other effect being a lower capacity stored in the battery.
