Default Re: Yamaha g2 Speed Cart ~$2000

Your stock motor was only designed to send your cart to 12-15mph. Switching to 48v adds 33% more voltage, speed and torque scales an equal amount (33% more), nowhere near the 30mph you are looking for. The motor i suggested is a GE motor sold by Nivel as the "raptor". There are other choices out there, but i suggested that one because i have done what you are wanting, and can vouch for the results.
