is there a way to measure the resistance in the connections between your wires in your lipos in your motor and your ESC Etc
I'm getting Heat at my connections over a hundred and fifty degrees Fahrenheit

The wire resistance between the battery and esc is insignificant. What connectors are you using for battery to esc connection? Esc to motor?

I use 6mm from esc to motor, 7mm from batt to esc, all soldered with lead free 4% silver solder. Haven't had any heat issues on the connectors. How's the temps on the esc, motor, battery?

An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. ... As the temperature increases, the metal ions vibrate more. There are more collisions with the electrons and so the resistance increases
Resistance has a direct relationship to the temperature of the connectors, at ambient temperature the connectors will show a lower resistance than when the connectors start to heat up.

I took the 6200 watt motor out, it was pulling 255 amps.Quote:

60/40 is not the best for electronics.
This is the stuff that Castle uses
Kester -SN96.5AG03CU.5 2.2%

That stuff is the shiznits! Thanks for the solder Larry!Quote:
