True, but that doesn’t help if the motor has the connectors sealed already, or for people who don’t want to splice small wires.
Personally I ended up buying 26 awg silicone wire (honestly better than the wire used on the motors to begin with and I should have cut more of the old wire out and replaced it with the new wire) and made two splices per wire for my sensors so that I’d have enough length to reach the VESC. I didn’t want to buy an expensive crimping tool I’d never use again.
I did do one practice run on some sensor wires I cut out of trash motors since making good splices at that size is a bit tricky. It is easier if you are okay with splices that are only held together by solder, but hard if you want the wires to hold themselves together before adding solder.
I am not qualified to answer this. I have low standards for motors and have never researched them aside from double checking prices before buying used motors.
