I had a 48 ezgo a few years back. Not sure about controllers or anything but I'm pretty sure I had a high torque motor. It would pop a wheelie if you laid the hammer down. I really saw no negatives about having electric. I had the charger rigged up to where I could charge it sitting on the trailer. It was pretty quite too, ran up on deer almost every time i took it out. Now that I typed this out I'm kinda wondering why I ever sold it...........
