Battery charging question.
We are in our 3rd fifth wheel now and have boondocked some. New to us 2016 KZ Durango does not have an onboard generator. Plan to get a 2000-2500 watt portable generator. KZ has only one battery and a...

I believe the trick is to get the converter voltage to sag to 13.0 or lower during initial charging. This is actually very difficult even with #2 wire connecting the battery. BTDT. The battery voltage actually pops up fairly quick at 60 to 70 amps plus the voltage drop in the wire and the WFCO is doomed.
If I fire up the inverter/MW pulling 160+ amps while the WFCO is charging it will shift right into boost mode.
Yes I believe the WFCO is supposed to give about 15 minutes of boost mode about every 24 hours and is probably what you were seeing. And that brings me to another story of getting stuck overnight at 14.4 volts boiling my batteries away. Did this more than once. I had to give up at that point.
