My thinking......and My Opinion. A P.D. retrofit is a relatively inexensive way to address the WFCO. I installed one on mine when the WFCO conked out. Went in very textbook perfect. The other thing is, most companys(companies?)use #8 or #6 wire from the converter/chargers to the batteries and they are installed at the factory as far from the batteries as possible...sometimes in the next county. There is lot of Charge Voltage loss in that distance. I ran a #2 wire from my batteries to the coverter/charger location to minimize voltage/charge loss. Result is, with my four 6v batteries, I can charge from 12.1 volts to 13.2 volts(float)in about an hour.

Our WFCO in our 2018 Escape camper decided to charge our AGM's at 20.3 volts destroying them. After getting our new SiO2 batteries we merely disabled the charger portion and only charged with our rooftop solar for the next two years. Worked great.
I received a different WFCO to replace the bad WFCO charger, installed it, but never used it. We sold the trailer last December.
We now have a 2026 Bigfoot 25RQ with a Progressive Dynamics 45 amp charger. By adding their "Charge Wizard" it charges our two new 100 ah SOK LFP batteries just fine, but it's also disconnected in favor of the 160 watt rooftop solar and a 100 watt portable. For the past two weeks in Arizona our SOK's have been topped off most days, but with excess ah's not topping off a day or two is just fine. The lowest we've been so far is 78% SOC.
Over two years ago when our WFCO charged at 20.3 volts I found a couple others who had the same experience with their WFCO's.
I'm glad our new camper has a Progressive Dynamics charger.
Enjoy,
Perry
