I added one 12v deep cycle 105ah battery (B) to the tray in my new Alante 31v immediately but really want to have three or four. So, I added one more using the storage bay adjacent to the battery bay. Due to trying to keep the wires as short as possible, when I added "C" I used 9" 4 awg wires, the same gauge as originals. When I added "A", I had to use 35" 4 awg cables and ended up with the connections you see here.
Although I do not have the solar installed yet, the wires on the far left on "A" are what I plan. I know it is not optimal, but due to space and keeping cabling as short as possible I will use 12" of 6 awg (the max that will fit in the charge controller terminals).
Any issues with how this is all wired, other than not being optimal?
