What do you do with the batteries in your 5er during winter? I live in Central OR and it can get pretty darn cold here at times. Do you leave them in the 5er and keep electricity to the converter or...
A charged up battery will stay along time without being connected... Being charged negates freezing to a big degree...
Here in Virginia I can leave mine in a charged state with my battery disconnect switch open... Other times I just leave power on my RV Trailer and it keepds the batteries up and going. If I am hooked up and keeping re-charged from the on-board converter/charger then I will check battery fluid levels on a regular basis.
