That would be more like ~340A. My calculations say that could be handled by conductors 1cm^2 for a 2m long cable. It would be awkward and bulky as anything, but possible.

We have 00 gauge wires on our chargers at work for our battery operated equipment. They have ~3m long cables, and output "only" 120 amps. The wires generally stay cool, or only barely detectable warm, except sometimes near the connectors. They're generally only warm to the touch there, but when they get a bit of additional resistance for whatever reason...
I'd want something a bit better than those 350A anderson connectors, were I getting anywhere close to that kind of amperage. Something with a lot more surface area.
