I have 55w 30L fridge and it runs on 100Ah 12V battery for 5 days to 10% rated capacity this is real life number. With 25C degrees temperature deferential (on average ) between ambient and fridge interior. I also run it in Eco mode when on battery mode and it consumes only 2A at 13V. Your...

You will be using braided one? Those are nice one. I could not find them on Amazon.ca

What's wrong with flattened copper tubing? Why you don't like it? I know you can buy, but sometimes the lengths is the issue, if its not standard assembly. Or if you need to make 90degree buss bar, copper tubing comes handy. You can do nickel plating or solder plating. Grade L tubing its 99.9%...
