Nice. I just upgraded my Yamaha to Alltrax XCT to go with my 14 Lithium Cell pack. The stock controller was about to die - did not like the fully charged pack! I just got the controller dialed in - max motor RPM set to 4000 (I have 8:1 gears) It now tops out at 27MPH with that setting. (Measured with my cell phone App) The 500A controller is set to 400A Max - recommended for stock motor. I set the Min Voltage to 42V or 3V per cell to protect the pack from under voltage. I had to flatten the throttle curve somewhat to get the throttle response I wanted. It's nice to be able to dial in those things!
