Want to leave 2 big 12volt batteries in studio to use for a 24 volt wire feed welder, but dont want to lose them from the battery bank. Run a trace C-60 controller, with about 800 watts of panels right now. Studio is about 30 maybe 40 feet from house. Can I run a pair of wires -- 6 maybe 4 gauge from batteries in houae to studio so they can charge while Im on the road driving and be ready and also be useable with the rest of the bank when home? Hope this made sense! In the house are 3 pair of golf cart batteries and 3 deep cycle 12 volt.
