Well, since I can easily explain/ The quality and size of the ground wire makes a difference in HP, but not 5HP at the wheels. That is more like 2HP at the wheels without a system. The type of metal is important to how conductive the cable is. I am not sure exactly what metal is "the best", but I am sure that what we have on our tours is not the best grade to be had out there. All hyperground is doing is selling you high quality cable kits at probobly a pretty steep price. Further studies might help you find the metal that is most highly conductive in DC voltage applications. As for me, I will know soon enough.
