High current 18490 (Same as 18500) from AW, the 15C means 15*1200mA -> 18A, as can be seen below it is probably a bit to high.
The cells are not maches perfectly for capacity, but acceptable. The 10A trace looks fine, 15A is a rather high load for the cell and 20A is too high.
Conclusion
The cells has fairly good performance, but compared to other 18490/18500 cells it is nothing special.
