The two cells are not perfectly matched, but they can easily deliver the rated capacity. One cell died during a 30A discharge, I stopped the other due to temperature.

Conclusion
The batteries are not perfectly matched and cannot deliver the rated current, it is probably a good idea to stay below 20A, but they do have the rated capacity.
