I have 99 club cart which has been converted to a 2000. (Controller, ect.) Right now i have charge the batteried over night. Once i go approximately 50 yards the cart then comes to a crawling speed. This is a 48 volt system, batteries show 51 volts in series. The charger will not zero out charge. What might the problem be. Any help will be greatly appreciated. Thanks in advance.
