The Q100 motors use a 9 pin modular connector, along with a extension cable that terminates with 3 bullet connectors and 2x3 plug for the sensors. If they don't include the cable any more, then you have to add it. The KT-controller from PSWpower.uses the same connector. I've never communicated with BMSbattery. Bought three Q100H motors at separate times and two other motors. I hear they're hard to deal with when theu screw up an order.
You might look at this vendor. They can sell the controller with the "waterproof" connectors. Also a finished wheel. These are the same connectors used in commercial bikes and are better from an install/reliability,

There's some people on the pedelecs forum in the UK that have built folders recently. Might have more recent vendor feedback,
