6x 62 = 500???? I don't think so

The difference for a new Club Car is about 20 extra miles of range. A big difference in range, but the life cycle difference is even larger. Lead is around 300 charge cycles and LiFePo4 cells are over 3000 charge cycles. If you tend to go through batteries once every 2 or 3 years, that's about 20-25 years for these LiFePo4 cells with the same usage.
what are those figures based upon?

20-25 years? how long have they even been on the market?

Here is the other advantage of LiFePo4 cells. If you wanted to and did not care about the weight or the $$$, you can add a lot more larger cells and increase your range to over 100 miles.
Again based on what, where R U getting these figures from?
