LiFePO4 Converter Change?
I just want to switch from lead acid to lithium, not upgrade wires and everything else. Finding a new replacement board for my WF-8955PEC seems to be complicated. Straight 14.6V continuous boost singl...

I have been looking at it and I see a lot of mixed reviews and their power factor is commonly referred to as being bad. I do like the fact that you can fine tune the top voltage but I wish you could tune the 2nd stage independently.
power max is top of the line.
With some solar controllers you can program everything. Why hasn't anyone done this for converters yet?

There's a very small pot that adjusts voltage for *both* the single-stage mode and the *bulk* stage when in 3-stage mode. It can be adjusted from 13.0 to 16.5v. Comes from Powermax preset for 14.6v. Haven't confirmed it yet, but I believe the float (13.2v) and absorption (13.6v) voltages remain fixed and are not changed by this pot.
