   Have an 2020 Yamaha electric golf car. 4x12 volt batteries. 
   The cart will make it around about 12 or 13 holes of golf then it will begin to die and slow down. Individually volt/load tested each battery and each one tests out okay. Water level in each cell is at the correct level. All cables and posts are corrosion free.
   Not sure where to check next?
   is there a way to check total voltage output while cart is running to see if it is 48 volts?

   To properly test the batteries in an electric golf car requires a special load tester that draws down all the batteries as if the car was running. You probably will have to have Yamaha do it unless you know of a fleet of the same car you have and maybe they have and will loan it to you. Also make sure they tell you how to do the test.
