Jsikes06,
Sounds like you have a SOC gauge that displays %. It would be a good idea to install a meter that reads the pack voltage. There are some good options out there and they do a pretty good job of allowing you to see what the actual voltage is in all different conditions.

Is your graph meter something that is on all the time on the cart, with the cart on or off?

@CCFanatic: my graph meter is hooked to the key switch it's only on when the switch is turned on
