FMF Doc - How batteries are broken in greatly affects the life of the batteries. Check out this link:

The suggestion I keep repeating is if you are going to own electric and want to get the most of your batteries, you should understand SOC and when your pack gets to 48.4 volts (50% SOC). That is the max distance you should drive, not what a salesman tells you. For battery break in you should NOT discharge the pack to less than 49.6+ volts (75% SOC) for the first 15-20 trips. Check out the table at the bottom of this link for various voltages and SOC:

A great test for a 24 hours demo, fully charge cart, take voltage of pack, drive the cart until the pack is at 48.4 volts. Ask the salesman why you only went 31 miles before the pack was at 50% SOC 
PS. I made 31 miles up, the new RXV may go 40 for all I know.... |
Thanks to all for the great feedback so far...
Regarding the 8 six volt batteries, only some dealers will install them as an option. Not all are doing it at this time based on my limited research. However, I do know that Advantage Golf Cars will install them for $490.
How long they will last remains a concern for me.
