The EzGo golf cart is powered by an installed conversion battery pack made with the newest generation battery.  Measured capacity at the full range of the battery 4.2-2.5V.  It contains 3 modules, 12 cells total. Total energy capacity rated by the manufacturer 3750Wh. The pack is very light - about 58lb. 

The EzGo golf cart is owned by our shop, it has the original motor and controller, but reprogrammed to the maximum speed of 19.5MPH and with the fastest acceleration possible (Thanks to Gary A, Orlando, FL). Motor is rated 3,200W, but during the tests the measured maximum peak power reached 11,000W. During climbing uphill the average power was 5,000-6,000W. Continuous driving about hour, 2-3 rounds. After hour the motor was very hot and was smell burning. 

The odometer was calibrated with no more than 3% error. The driver tried to keep all the time the maximum speed of 19MPH - there is no difference in the maximum speed during climbing or rolling down. As result the average speed was 15.5MPH.

The pack installed for the tests is similar to:

Golf Cart Lithium Conversion 3750Wh Battery Pack GB4682-17 

 VOLTAGE/ MILES TRAVELED DIAGRAM

The total miles traveled until the BMS stopped the discharge were 42. The BMS doen't not stop the power for safety reason for the diver, avoiding sudden stop. We recommend using 42V as a minimum which will reduce the total miles on this test to 35 miles. After 42V there are no not so much power left in the battery.
