The two cell do nearly match and can deliver at least 30A with a minor capacity loss.

Conclusion
The batteries can deliver a lot of current, but capacity is in the low end for 21700 cells. I.e. these cells are mostly interesting if there is a need for very high current.

Thanks again for these reviews..

“Diameter: 11.5mm” is likely a typo.

That do sound a bit on the thin side.
Thanks, I have fixed it.
