Watts is watts?

Finnster is mixing up certain things;

efficiency is efficiency. With the hottest setups i used (120A plus nibbling from the batts) , i never got hot wires/plugs. Heat means less efficient, it's not true that a high current setup runs less efficient. and it's not all about internal resistance either. a HV setup runs more efficient on the same resistance than a HC setup.

Like i said earlier, with a higher voltage, the resistance becomes less relevant. Look at the HV cords hanging over land. they are made of aluminum, while copper has got a lower resistance. (but not a better weight/resistance factor) but due to the high voltages this rather high resistant aluminum can be used. If they put 110V on it it would be gone in a few km.
