Sorry, What I mean is, I was told that if you batteries, ( either 6 volt or 12) are connected to your trailer, and being charged from the converter you shouldn't connect a charger that is connected to your generator and then to your batteries. I heard this can cause damage.. my thought was to be able to disconnect them from the trailer temporarily while charging them with an auxiliary charger.
You have been given incorrect information. Multiple charging sources are not an issue for the batteries, charging systems, wiring, or operating 12v items at the same time. All 12v items are compatible at voltages from 10.5 to 15 volts.
