You can always change them if you get different ones, or the motor wires can be soldered direct to the ESC ones. Just be sure to get good joints and insulate fully, with heat shrink.
Watch out for the bullet sizes - I have had every size from 2mm up to 5mm - only recently I ordered some 3mm bullets connectors only to find out they were 3.5mm on the motor! I've had a good look at the listing and can't see anywhere it lists the diameter.
The only problem with those nice connectors is they are 30A max. I am going to get some next HK order anyway, they will be handy for mini size builds like the TT where I am always taking out or breaking the power pod.
