Club car positive terminal overheats during operation

I would check the battery cables that connect them to the other batteries to ensure they are clean, tight, and in good condition. If they are loose consider using a lock washer to help keep them secure. If they are getting hot it will just be a matter of time before the battery terminal post melts. I would just replace the cable with a new one and see if that helps. A lot cheaper than a new battery. Hope it fixes it.
