Huh? The wire length limits the charge current? I may be dense but you are going to have to explain this to me a bit more.
Wire has resistance, enough wire (his cord is approximately 30 feet long)has enough resistance to drop the charge current to his target 10 amps. That's an extrememly mild charge rate for an A123 cell pack that will happily discharge at 80 amps.
