I've tried to answer this myself but there are so many tables out there it's hard to know, so I was looking for some direction.
I have 2x 12v 100ah batteries in parallel. Individually they can deliver 100amps, so in parallel I'm looking to size wire for 200 amps.
Everything running from the batteries is protected by an OCD, breaker or fuse, and the max size there is 150a. I still think I'd be sizing for the batteries though. Some charts say I'm fine with 1/0. Others say go up to 3/0. There is no run of the wire that would be great than 4-5ft full distance (pos+neg both).
1/0 - >https://theinverterstore.com/faq-items/what-size-of-cable-should-i-use-with-my-inverter-and-battery/
1/0 -> https://baymarinesupply.com/calculator
3/0 - >https://www.omnicalculator.com/physics/wire-size
3/0 ->https://www.cityelectricsupply.com/downloads/Ampacity Chart.pdf
