The discharge curves tracks fine and the cell has nearly constant capacity up to 15A. At 20A one of the cells got too hot and I stopped the test.

The cells gets very hot at 20A.

At 30A they discharge before I measure the heat, but they get even hotter.

Conclusion
This battery has good capacity and can deliver a fairly high current, but the 30A/60A is too optimistic.
