converter problems

I installed 2 12 volt group 27 batteries

If I unplugged the electric, those batteries wouldn't run my furnace for 1/2 hour. The converter won't kick in until batteries drag down to 12.3 then charge up to 14.6 volts so I have pulsating up and down lights and furnace.

The converter is quite warm to touch most of the time. I think its 55 amp converter. I've owned many campers and never had this behavior.

If I add batteries should I enlarge my converter?

I took batteries to Auto Parts store, they both tested 100%...

I have two batteries in my 5er with a 55 amp converter with no issues.

If your batteries wont last more than a 1/2 hour without shore power than you have an issue with your batteries.
If there fully charged they should last a lot longer.
A converter will cycle like you mention if there is a bad battery.

Get a second opinion on battery condition.

How are you checking your voltage?

I had a WFCO converter and per the mfg it was working correctly.
But it would not go into bulk mode even when batteries were deeply discharged. So I replaced with a IOTA converter with the smart charge option built in. Plug unit in and it goes right to bulk mode....
My other unit was never charging properly. We did a lot of dry camping and also installed a 130 solar panel.
Life is Good....
