If the tag says 13 amps load you can count on close to 130 amps from the 12 volt battery. (amps x10)
Best to stay away from parallel wires unless the inverter has dual input terminals. Get the right stuff. I posted a link above.
As far as equivalent wire you need to convert to circular mils to add the cross section of copper. But again try to stay away from parallel.
Cross section area is on this ampacity chart:

Need 4x #10 to make #4
I didn't think I was calculating that correctly. So that's 130 Amps. Is there a time factor in that? actually I think I'll start a new post for that question so this hopefully stays on track.
And thanks for the link above for ordering wire. I try to support the local guy so I'll try the local welding supplier first. But if the price difference is large enough I'll have to go online.
