Do I need a better converter?
Just replaced original 80ah battery with 2 100ah batteries. When dry camping for 3 nights the batteries were steadily lower after each charging during the allowed generator times. 1st night when fully...

Ok I’ll try to give some more info. They are regular lead acid. First night they were 100% because it had been parked in my driveway plugged in for 2 weeks. I was charging for 2 hrs in the morning and 3 hrs in the evening. I did periodically shut the converter off to run a microwave but that was very limited. Probably 15 minutes total per day. I’ll have to look but I know I have a WFCO 8930/50. Trailer is 50 amp. There is a breaker that says converter. Am I right in thinking it is a separate unit?
A WFCO will seldom exceed about 10-15A charging current and seldom go above about 13.6V. almost never go to bulk mode. So with only 10ish charging amps you (a) never get fully charged and (b) seldom in 3 hours or so will do much for the battery and (c) even if left on for days it will NOT get the battery fully charged. That takes a charging voltage of about 14.6V for a while.
BTW your problem is pretty typical of campers I know that had WFCO chargers and could not get the batteries replenished with a generator in reasonable time.
