ez-go 36v out of ideas

[George Lewis]

Batteries are 2 days old and charger the same. With a full charge the cart will ride for about 30min straight with out an issue. Then it will loose power. Turn off the switch wait about 1 min and then it will run at full power for about 5 min and do the same thing. And this is flat ground not up hill or anything. Any help would be great

Have you checked that the controller isnt overheating and shutting down? Are you sure you got the same voltage batteries? If 8 volt batteries were put in place of 6 volt you could have a problem.
