I have a 97 Club Car (48 volt) electric golf cart. It would click and or jump just a little. Before it started the click or jump and jerks as we would ride it. It was like it we totally let off the pedal and the mash it again. After leaving it on the charger for a couple days it would run for maybe 2 minutes then go dead. Bought new batteries and doing the click thing when I put in Forward or Reverse. Charger did complete the charge.
