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...

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)
Apparently the contest is between what the charger (Victron controller here) can be set to for Float and what to set the charging voltage at for Float per battery specs , AND what the tail amps should be set at so they are above what the controller gets to in amps before dropping to Float (so set that low enough so not to mess up the monitor-- or is that the other way around?-- while the controller charges to 14.x per battery specs but the monitor "charging voltage" is set to just under the Float voltage?)
Thank Goodness I am not an LFP guy, so I don't have to figure that out in my spare time! :)
Also AFAIK for LFP if you set the Vabs at less than 14.6 it will still reach Full but take longer in Absorb. So if you set the Absorb time at 20 minutes as for 14.6 Vabs, that will not be long enough for some lower voltage Vabs, but I don't have a reference table to say how long for which Vabs.
