My friend indicates that the batteries being drawn down to 25% (indicated by voltage only) is not the norm, but it has happened several times when he hasn't been able to run the genny. The batteries are the Everstart Maxx group 29 Marine batts from WM with 114 amp hours rating.
Is anyone concerned that the external battery charger and the trailer's converter could be in use at the same time charging the batteries?
I would think that this setup really wouldn't work correctly. If one of the batteries was disconnected from the trailer and the external charger were attached to this battery, it would charge as it should. If both batteries were disconnected from the trailer and the external charger were attached to BOTH batteries, charging would work but would be quite slow. If the generator's power was attached to the trailer, equivalent to shore power, the converter would supply 12V power to everything in the trailer, including any attached batteries. With the converter supplying 12V power to the batteries, what will the external charger see? 'Apparently' charged batteries? If the charging process were started with the trailer NOT plugged into the genny, the external charger would see batteries needing a charge and would attempt to charge them. Now if the trailer is plugged into the genny (shore power) and the trailer's converter is powered, what will happen to the batteries then? They were being charged externally and now another charger is potentially supplying a charge??
I would think that this just wouldn't work correctly and that my friend should charge with either the external charger or the converter, BUT NOT BOTH at the same time.
