It seems like you already have settled for 2/0 gauge for your batteries. Beeing a metric guy I'm not so familiar with the AWG system but with batteries and high current applications "bigger is better". And 2/0 seems good. There are of'course ways to calculate the needed gauge considering the load, distance and current. But hey, there is no thing as to big. Well maybe for your wallet.Thanks! I'm super excited about it.
I got started on the wiring last night. Almost 300' of wire done already. Ouch.
I was planning to run 2/0 to the main batteries unless that seems way overkill.
Just wanted to give a heads up if buying start/jumper cables to save money. Here in Sweden the jumper cables are often CCA which is a copper clad aluminim wire. Not the same as a true copper wire. In general you need to upsize one gauge larger (Somewhere around those numbers I guess...still a metric guy) if using CCA instead of copper.
Maybe this is not applicable to your situation but something to have in mind when you are comparing prices and realise that jumper cables are so cheap.
As with everything else you can go deep into the subject. How wire strands are wrapped and stretched when making the wire and the difference in premium and standard wires. But it's not rocket science either: proper gauge + good connections = good to go.
Really looking forward to se more progress.
