Two chargers on same battery
I recall BFL (I think it was) saying he could use the Vector 1093 on a battery while it was also being charged, albeit feebly, by the stock converter charger. We dry camped all week, with no solar,...

From a previous HTT I had a deck-mount IOTA-55 w/ IQ4 controller (HTT came with a "dumb" single-stage Elixir.) The new TT has a WFCO converter, not known for going into boost mode easily. The IOTA seems to start in boost mode whenever it's first turned on.
The IOTA got mounted to the ceiling of the front pass-through and it's a hard-wired 3' cable run to the dual G27 batteries. For 110V I tapped off a front bedroom outlet and fished a cable to a switched outlet for the IOTA. In the home parts box I had a compatible breaker for the WFCO so it got put on its own circuit. Now I can turn either or both converters on & off.
With cg power I run solely on the WFCO. For charging off the Honda 2000i I flip the disconnect switch on the batteries. The TT 12V circuits now run off the WFCO and the full boost output of the IOTA goes to the batteries. And since the WFCO isn't in boost mode the TT 12V side doesn't see the high boost voltage.
OK, it may be overkill but it works for me.
