I built R/C lawnmower, runs off (2) 12-volt lead 18 ah batteries, Sabertooth 2x32, a FLYSKY R/C controller and Arduino central computer. The robot works great now I want to improve, and make it safe. To the 80-amp R/C ESC that runs the main mower blade is a brushless 3 wire motor at 24 volts. I thi…

If wires get hot thicker wire (or silicone insulated wire) should be considered - silicone insulation can stand very hot wires without damage, often used to save weight in RC aircraft etc. Heat loss in a wire is proportional to current squared so a good solution is go to a higher voltage thus red…

In answer to your question, the greater the wire's cross-section (ie fatter the copper) the less voltage loss it will experience and hence the less heat it will generate. So the thicker the wire the LESS power you will be wasting. Heat generated (in watts) - the wasted power - is directly proportio…

Ok so if bigger wires make it better with no consequence to the electric supply of power - I will try and use 6 gauge wires. The PROBLEM with that is, the 14-gauge wires OUT from the ESC are SOLDERED to the very small circuit board, as it's designed to be installed in a R/C airplane to save space a…

I'd suggest you use EC5 connectors to couple the 6 gauge cables to the ESC output leads, and try and increase the 14 gauge output leads either by doubling them up or using whatever gauge you are comfortable with. you need 4 wires of 14 gauge in parallel to be equivalent to 6 gauge but providing a si…

Wawa: Forget about everything. Slightly warm wires after 40minutes is NOT a problem. Leo.. Probably the best solution all round. Too often we try and solve problems that don't really warrant the effort. Unless "warm" actually means 'hot' then as Wawa says "... Not a problem."

10 gauge wires warm at (80?) amps R/C esc

Warm wires is not a problem, but you loose a (tiny) bit of power.
Thicker wires (or a second wire in parallel) reduce (halve) the problem.
