Is State of Charge linear?

[mattadata]

I drove my cart 7 miles today. After resting for 30 minutes or so, the voltage is at 38.1 volts, which is about 96%. At this rate, I could drive 46 miles and be at 60% SoC. Seems unlikely.

Does it drop way off at some point?

I don't think its completely linear, and I think it could vary from battery manufacture. JohnnieB will most likely be here soon with some fancy charts and stuff and a better answer!

For reference, I have relatively new Trojan T-105s. Feb 2015
6 X 6 volts

My notes for Range Test (per JohnnieB or Sergio)

1) charge pack
2) rest 12 hours
3) record voltage of pack
4) drive X miles
5) rest not less than 1 hour
6) record voltage
7) difference of voltage gives mileage rate (X miles/ voltage 3- voltage 6)

This is from my rough shorthand notes. This would be a rough estimate. Of course any up slopes and down slopes will change results greatly.

Any corrections would be welcomed.
