LiFePo4 batteries have 3 times more energy density than a run of the mill lead acid battery and they are 1/6th the weight for the same capacity. So for a standard T-105 lead acid Trojan 6-volt at 62lbs the equivalent LiFePo4 cell weighs 8.9lbs. So for a 48v cart that is 500lbs of lead. For LiFePo4 that is only 67lbs. Weight = Range

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.

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.

When you factor in the life cycle difference the LiFePo4 cell is more economical. It's all about the upfront costs.

If I can be of help to someone who wants to outfit their cart with Lithium Iron Phosphate cells, please PM me.
