Re: Mounting control box and controller on motor
I mounted a 1/4 inch thick aluminum shelf off the two bolts at the top of the adapter/transmission and a bracket bolted to the end of my motor. The shelf is around 4 inches above the motor. The charger with energy meter on top, relay box with battery heater controller on top, and DC/DC converter are mounted on this shelf. No issues over the last 2 1/2 years. As you said, leave slack for movement. The motor does of course radiate some heat, but it remains below about 65 C typically in summer, so not a lot. The controller, on the left is mounted off the motor end bracket, suspended over the passenger side "fender". There is a finned heat sink bolted to it underneath.
