The EzGo golf cart is powered by an installed conversion battery pack made with high quality Chevrolet Volt 2015 batteries - 50Ah measured capacity. It has configuration 12S6P.  Total energy capacity 4500Wh.

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 3200W, but during the tests the measured maximum peak power reached 11000W. During climbing uphill the average power was 5000-6000W. As a result the motor almost burned during the tests. It was running nonstop for an hour and became very hot and smell burning. 

The odometer was calibrated with no more than 3% error. The maximum speed reached was 19MPH - there is no difference in the maximum speed during climbing or rolling down.

The pack installed for the tests is similar to: 94Ah 45V Lithium Golf pack

Here are the results: 

 VOLTAGE/ MILES TRAVELED DIAGRAM

The total miles traveled until the battery reached 42V (3.5V per cell) were 40. No BMS for discharge protection installed. We recommend using 42V as a minimum, since there is not so much power left in the battery. At the 42V point - we had 3 miles more left.

On a grassy (golf course) terrain expect less miles.  

Video of the test track

Total round trip traveled 0.55 mi including: 0.2 mi climbing, 0.075 mi flat terrain, 0.2 miles downhill, 0.075 mi flat. 

Average speed: 13 mi/hMPH with frequent stops and acceleration.
