I just discharged 3 of these packs in series from 4,1 --> 3,5V and got 4,18Ah from them.

Does this seem about right?

Ok, thanks for answering. I now also tested my 3 other packs and they also put out nearly the same amount of Ah from 4,1v-->3,5v. 4,17AH 188Wh

Is it a way to calculate how much of the full capacity of a battery there should be between to specific cell voltages?
Like 4,15 --> 3,6 should give 85% of max capacity? If that was understandable.

I think 4,17Ah is about what you get in this SOC span. You probably will get litle more then 5Ah in 4.2v-3v discharge.
