From what I've heard the WFCO's don't go into bulk or fast charge mode easily. And a 35 amp charger won't charge dual batteries very fast.
My old HTT had a single-stage Elixir converter that wasn't good at charging my batteries (dual G27's.) I bought a deck-mount Iota 55-amp converter from Randy and mounted it in the front pass-through. I drilled a hole in the floor and ran the charging cables (all 3' of them) to the batteries. The Iota was powered by an extension cord plugged into my Honda 2000.
I traded the HTT but kept the Iota. It'll go in the front pass through again but I tapped into a bedroom outlet and ran a 115V line with a switched outlet into the pass through. The Iota will get screwed to the pass through ceiling to save floor space (and keep it from getting beat up.)
I had a local car stereo shop make cables for me. $1 / ft for very flexible 8-ga cable and $1 each for gold plated ring connectors crimped on.
The new TT just got refitted with LED lighting, and I put an on-off switch on the radio / DVD player so the current draw is ZERO when the unit is "off." My only full-time load now is 100ma for the propane detector.
The Iota is hard wired to the batteries but I have a disconnect switch between the batteries and trailer 12V circuits. When I'm on generator the full output of the Iota will go to the batteries and the factory WFCO converter will power the rest of the TT. WFCO's don't need a battery to supply clean 12V power.
I recently upgraded my TT and I kept the IOTA DLS45 (45amp) Series M with the IOTA Smart Charger IQ4 from my previous trailer and was hoping to use it somewhere, sometime. The new TT has a WF8955 (55amp) and dual G27's currently. I was thinking of swapping out the WF8955 and installing the DLS45 but when I read your post there seems to be a better use for the DLS45 without removing the WF8955. Could you share what is the best way for me to accomplish similar results to what you have ?. My Honda EU2000i is what I use to charge my batteries when boondocking.
Thanks
