Absorption voltage

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.

Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.

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?

@Matt23

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.
