That amount of voltage drop (0.7 Volts) is significant when charging batteries. Has anyone else had this issue? I am considering the purchase of an external battery charger that I connect directly to the batteries. Thanks, -Mike
You could use an external charger, but I think you will find that to be a bit of a hassle. Better would be to find the caused of the voltage drop. Remember, since you see that drop when charging, you will also see a drop when running only off of batteries (IOW, boondocking), which could actually be a bigger issue. I would check ALL connections between the battery and the convertor. Including frame grounds, terminals, fuses, and wire sizes. Since it is a small trailer, it might even be possible to just run new larger wires between the battery and convertor.
