Not in this case. The 24 and 36 volt kits have a regenerative brake, which means it functions as a charger when the wheel is turning, but not pulling. Actually I am using a small PM motor with a weed eater engine as a stand alone charger. I tried an alternator, but it is too heavy to suit me. I am looking for a small, light one though. The advantage of the PM motor is that it also works as a starter. Sorry for the confusion.
