I have to say some thing here. Although I believe I know what jgalt is trying to say, I belive he said it wrong.

The thinner the wire diameter, the higher the resistance - so you have a greater voltage drop.
Going with the biggest guage wire possible, and keeping your cable clamps and connections clean is the right approach.
The smaller the GAUGE of Wire the higher the resistance. You typically want the smaller wire strands within the larger gauge of wire. For example look at welding cable. Large gauge made up of many small wires.
Electricity flows on the outside of wire, not through it. Corrosion is one of the biggest problems. Corrosion on wires is like kinking a garden hose. It won't let the electricity flow.
Buy the largest gauge cables that you can. Then check the connections at each end. If you can flex the cable and see the bare strands of wire I would recommend sealing the Terminal end to the insulation with some shrink tubing.
Good luck
