My 03 cc is driving me crazy!! As you can see from the other post it is a slow cart but now it will take off and within 5 min it is to a creep. It is a 48 volt and all batteries are 8.3 and above and it has 51 volts total.This is after the charge and after the slow down. If it is a speed controler how do I test it. Or would a speed controled take off ok and then slow.
