It could be the alternator. If the alternator is bad and not charging the battery
when you drive. Your battery will be dead in about 2 days depending on your driving distance. Even a new battery will die without a charge.
Check your battery voltage again. then check it with the engine running if you can.
The alternator regulator is cheap and easy the swap out if you need to. good luck.

Unable to check voltage when running starter will not crank engine it does not move full rotation

I've seen this far too often. Throwing money/parts at a car and it doesn't fix the problem.
Join BMWCCA and your local chapter https://www.ctvalley.org/. They should be able to recommend a very good indy garage in your area.
Could be as simple as a severely corroded ground strap.

Is the battery fully charged?
Have you tried turning the motor by hand?

Plan on trying to turn by hand and checking the earth ground I feel it flimsy, but going away for couple months Monday so if I don figure it out tomorrow it'll have to wait until I get back
