if I have a 10k pot then I'll get 10k across the in and out regardless of the wiper position.
Yes.

I guess I knew that anyway looking at how the pot is designed and using my knowledge of voltage dividers. It just worried me is all. Sorry, just needed reassurance.
Measure, measure, measure. That's the secret.

One last question on this subject, my battery outputs 4.2 peek. So, 4.2 is going to be the largest voltage going into my divider. Lets imagine that for some reason, maybe plugging in to charge or some kind of surge, lets say 4.8 got sent into my divider. By its nature then, the divider would output something higher than 3.3.
Yep. And that's why I'd aim below 3.3V. Somewhere between 2.5V and 3.0V is good. You've got enough resolution on the ADC.
