Panda: FYI, the setup guide algorithm takes vehicle weight and target speed and produces a "required power" figure. Then, calculating the current draws (average and burst) is a matter of joule's law based on the voltage used. As such, this is not exact, so keep that in mind.
I realize that real world testing will have different results. I was just showing heat loss as a calculation. I could've added further losses from a nominal 200mm of wire but I forgot and today I don't have time.
BTW the sliders used in the car setup guide is a handy tool
