I was actually expecting someone to crunch the numbers for the electrics in their car. CHILL guys!
Hey, I was going a little over the top with the numbers to make the point that it does matter which wires you use, just not for us mortals.
For those wanting to know some real numbers, let's say:
Copper wires: a=0.017
Length 20cm=0.2m
Diameter=3mm
Temperature=20°C
R=(0.017*0.2*4)/(pi*3²)=0.0005Ohm
Thus the voltage drop is actually 100A*0.0005Ohm=0.05V per wire.
For a 4000kV motor that's 4000*0.05*3= 600rpm
But still, for the top drivers, that is important. For us mortals and me as an amateur, I don't care.
So if you shorten the wires to half the size, the loss is cut in half also.
And don't forget, you probably loose most by using connectors.
All that said, I never cut the wires and use connectors, just because I like to switch and this way is the easiest (be it messiest) way for me.
But then again, it wouldn't matter anyway because my driving is, to say the least hilarious.
