One other thing you might want to keep in mind is where the physical connections end up on the outside of the controller when you are all done.
On my Curtis controller, the big B- connection is right next to the 3 small pins for controller power and potentiometer -&+, which wouldn't be a big deal except that it's pack power going to the controller power pin.
That means that ALL PACK VOLTAGE is separated by about a centimeter.
I fried the controller power female spade connector right off the end of the wire taking it off one time. (I think power was disconnected to the main battery pack, but controller power was wired up separate, something like that)
Anyways, try to design the controller so that you don't need tiny hands and tweezers to keep from frying things when connecting and disconnecting.
