For flat paved road use, you can estimate 1.5 Ah per mile. This has been true in my case over 10 documented rides from 8 miles to 27 miles per trip. My 72 Ah battery gives me a range of 39 miles safely. I charge after each trip of a mile or more.
Your cart drive setup, speeds, conditions, etc. may affect this estimate. You could expect 20 miles per charge cycle based on this. (48Ah, -10% settling charge, -20% minimum SOC, divided by 1.5 equals 23 miles.) My formula may not work for all users.
If golfing, I'm not sure what this mileage would correlate to.

What's a good calibratable...if that's even a word...but SOC for a lithium pack? A generic one.
