Is 13.7 float voltage too high

I have recently changed to a Lithium Super Pack 12v/200Ah. My MPPT controller does not have a setting for lithium and the float rate is 13.7v. Is this too high?

Hi @Mike Lewis,

float voltage for the Superpack is specified at 13.5V. So 13.7V is definitely too high, especially if the lithiums stay in float for longer time.

If they are discharged constantly after a full charge, I think it's not a problem.
