Calculating wire size and voltage drop
I'm in the process of adding a second battery bank. The bank is two 6v GC2 @220 AH. I've finally nailed down some exacting measurements and have totalled the two runs from the bank to the distribution...

IMO, anything up to 2/0 is easy to work with. I have everything from #10 to 4/0 in my rig. Only the 4/0 was difficult. Westend, if that 90A of inverter goes through that wire (90"/102"), size your wiring for that. You can go a little small if that 90A is short in duration. And what mean by small is size to current handling. With inverters you don't want the low voltage alarm sounding off so keep the voltage drop above that.
