I've tried two different controller/motor combinations with the scooter now, and both seem to work well. I can't speak to their durability, but they both seem to deliver their rated power without getting hot and they cut back power at low voltage. According to my wattmeter, I can get over 800 watts peak from the 35 amp controller and 600 watts from the 25amp one. You will also need a throttle control and a set of brake levers. You could use a Cellog8 as a cheap BMS to cut power to the charger or maybe a simplified version of the one you already designed for your Enginer pack.
