Without the extension cables everything works fine. l have had this problem on three different ESCs and with the extension cables between the motor and the ESC or the battery and the ESC. I have also swapped the motor and still have the problem. It seems I am dropping two much voltage between the ESC and what it is connected to. The extension is approximately 11.75 inches and I am using 12 gauge wire made for use electric model airplane applications.
Has anybody else had this problem.
What size motor, Esc, lipo are you using
12 gauge wire should work ok for up to a 60 size motor, bigger than that, you might want to use 10 gauge wire, I agree with others, that a bad solder joint or loose bullet connection might be a problem too, Take care, Chellie
