Lifepo4 float setting?
I have not had to deal with a float setting so far with PWM controllers but I have a Victron 75/15 coming tomorrow and reading up on the settings,it is confusing especially the float setting..Some say...

Even a few RV lights on could prevent drop to float. I would be more inclined to go 20% to 50%. No need to taper an LFP to full like lead-acid.
IMO not being any sort of expert, that looks good for charge efficiency, but IMO the tail current should be 2% as chosen by Trimetric or even less as is really the case with LFPs (AFAIK)
So how do you get it to Full as required to zero the monitor and do the supposedly once a month balancing act? How can you tell when it is really Full so it can do the balancing act if the monitor is not set to get to Full?
IAW how to make sure the monitor does not drop to Float (never mind what the charger does!--who is running this anyway?--tail wagging the dog?) too soon so the battery never does get to true Full?
