Don't see what PWM vs MPPT has to do with it.
With both of my Renogy PWM controllers,the float is not adjustable,it is preset to what the boost is which is adjustable..It appears with the Victron,float is adjustable as well as some other parameters the PWM will not let the user change..
I guess I could just leave it at the Victron lithium pre-set but was looking for the best settings for a generic LFP battery..Battleborn has all the recommended setting for there cylindrical cell battery and the Victron controller but I would think there is a difference in cylindrical and prismatic cells as small as it may be..
