Question
Solder or use bullet connectors when making my ESC wires longer

Hi

I need to make my Esc wires longer and I understand that I need to lengthen the motor/esc wires. My motor wires are a smaller gauge than my esc wires, so I'm going to use the same gauge wire as my esc 14awg is this correct?

Is it best to solder the wires from motor to Esc or use bullet connectors both sides from the motor to Esc?

Thanks

Jus

As long as the wire gauge is equal to the ESC there should be no problems, (other than the extra weight).
If the motor was drawing a very low current compared to the ESC's rating, then you could drop a gauge to save weight, but smaller gauge can also mean slightly higher resistance.

With extension leads, I personally still like to have connectors at one end, either the motor or ESC end depending on which is more accessible, (solder at the other end). It allows me to reverse the motor if required, as invariably it will run the wrong way.

Alway solder when you have a choice. Better mechanical and no chance for corrosion.

An electrical designer friend suggested to use a 1/4in length of brass tubing rather than butt solder or parallel and heat shrink over it turns out smooth! I suggest extending the motor wires and ad bullets and leave the esc stock xcept for adding bullets(motor side)
