Quad wire size?

[DavidAB]

On a quad using a 3cell 11.1volt battery, my ESC's have 16awg wire. The four motors are connected in parallel so what guage wire should be used to connect them all to the battery? What would be safe to use?

Thanks for any advice.

The wire size is determined by the maximum electric current drawn by the motor.
So you need to know that first. There may be some clues on the motor's datasheet.

There are many cable manufacturer's websites that will have a chart.
Or you can google "What wire size is needed to carry X Amps ?"

I understand this, but what current does a quad motor draw?

There are many different quad motors of many different sizes, all taking different currents !
Big ones usually take more than small ones !
The manufacturer's datasheet for the motor will indicate the maximum current that it should draw.
Or possibly the supplier you bought it from could advise you.
If you are building a drone from a plan, it should state the wire size in the instructions,

Thank you.
