The battery handles up to 15A nicely, the two cells tracks very fine.

At 15A the cell gets fairly hot

At 20A I had to stop the discharge due to temperature.

And also at 30A.

Conclusion
The cell can handle a good amount of current and has good capacity, but rating the cell for 25A continuous discharge is a optimistic.
I will call it a good high cell.
