Behind my fuse box is a GPC 55 max smart battery charger (55 amps) 2 old man, To answer your question, I guess the genset would be powering the converter... I have my shore plug plugged into the genset. I wasn't really thinking straight. If I was using an auxiliary charger, I could just unplug my shore plug and that would kill all power to the converter. But from what I have seen on the forum, even having power to the converter while charging the batteries from an auxiliary charger will do no harm. I guess I just want to have my batteries back up as much as possible whenever possible. The biggest draw will be the furnace over night as we have to keep our 16month old... and the wife warm during the night. During the day we have the honda 2000 to power the micro wave, and any other accesories.Re: charging 4 Six VoltsSorry, 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. I have a honda 2000, And the converter, Im not sure off the top of my headRe: charging 4 Six VoltsSo, maybe I need to invest in a more powerful charger.. Even when camping..... Im pretty sure you cannot hookup a secondary charger to your batteries when they are connected to the trailer. So, would it be best to instal an isolator so at the turn of a switch disconnect my batteries from the trailer and then connect say a 40 amp charger to my generator and charge them from there? 1 hour in morning, and 1 hour a night, will probably put more juice back into them then if they were just charging from the trailer converter!! yes no? maybe so?charging 4 Six VoltsHey there, Have read lots on here and have found great info in regards to batteries, but nothing linked to charging 4 6 volt batteries at a time with one charger... is it possible? if it is will it be very slow? Any info would be great thanks
