Conversation Between Frank7 and Rickg

My club car DS (48volt) seems to be loosing power and torque. My speed has dropped by 3 or 4 mph. Torque is noticably lower (takes longer to get to speed. I checked voltages on all the batteries and they are charging up to over 54 volts. I'm thinking there must be some type of controller? This happened suddenly. I'm down until Sunday then gone until Thurs.
