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...

Good stuff, thanks guys! Yeah, I'm using Molex brand lugs and welding cable. I'm crimping and using heatshrink to seal the lug and wire connections. When all the battery terminations are completed, I'll break out the terminal sealer, not mil. spec. stuff but is working out OK for me on my vehicles.
I had planned to pull the two cables, a pair of 14 ga. (AC run) and the battery sensor wire through a 2" pipe, transversing the bottom of the trailer. I had forgotten about the propane pipe and a center frame gusset that will be in the way. New plan is to put it into EXN or some other type of loom.
Thanks for the heads up on AWG vs SAE and diameter, Mex. I've been buying a bit of stuff through Waytek Wire, mainly because they're local. They don't publish everything but a phone call is all that is needed.
