RXV (AC) vs CC Prec. (DC) - Leaf packs compared after 27 miles

[MCJEFE]

So this morning we were heading out to the other side of our community so I decided to take advantage of the long run to compare the efficiency of the 2 carts. We started out with 2 completely charged (57.1v), identical 14 module Leaf packs. The modules for both packs came from the same 2015 Nissan Leaf with 29K miles.

I know that this is not an apple to apple comparison and the RXV is handicapped with larger tires.

'16 Ezgo RXV:
22" tires, 255/50-12 EXCEL Classic DOT Tires, BobBoyce tune to the factory 235 amp Curtis AC Controller. factory AC motor.

06 Club Car Precedent:
20" tires: tires20x10R-10 RHOX RoadHawk Tires, Alltrax XCT500, 500 amp Sol., 2 Ga. cables, OEM motor.

The carts were both run together the entire day. The overall run was a good mix of terrain including some small hills but was mostly flat pavement on commercial/residential streets. Speed was typically between 18 and 22 mph with lots of heavy acceleration.

Both Carts started at 57.1v and at the end of the day the DC Club Car Precedent was at 53.4v and the AC RXV with the larger tires was still at 54.1v.

Man I do like the Club Car but I love the RXV!

The bigger tires probably gave You an advantage with the lithium setup.

Large current demands have much more impact on a lead acid battery due to its Peukert number being so high, meaning the AH capacity is reduced by the increased load current.

Lithium batteries have a Peukert coefficient of almost 1 so the acceleration does not have as much impact and the large tires give you an advantage at cruising speed.

The AC drive system is however more efficient as well.

Have those 2 leaf packs been tested for measured ah capacity ? So would you say the rxv ac system nets about 25% more range and run time over the club car?

I did get around to testing the batteries myself just for shits and giggles and came up with right at 90AH of useable capacity with my current settings. I think the RXV is around 20-25% more efficient.
