Right from the Manual. And there is nothing on your cart like an OBC. You have a fully automated charger.
As long as the charger is allowed to shut off by itself, the batteries should be fully charged. If the CHARGER ON light has not shut off, the batteries are not fully charged. If possible, allow the charger to complete its charge cycle before disconnecting the charger from the vehicle.
Light Display:
The Ultra-Power II features a range indicator that consists of three red lights and a manual stop button.
This feature gives an indication of the vehicle's expected range as well as providing a diagnostic tool.
The three red lights are labeled 18 HOLES, 36 HOLES, and FULL RANGE. These lights will be illuminated as
the on-charge voltage reaches the predetermined thresholds. When the charger shuts off after a normal
charge cycle, the red CHARGER ON light will turn off, but the range indicator lights will remain on until the
charger is unplugged from the vehicle. Anywhere from zero to three red lights will be on.
