This is a high current 18490 cell (18490 is basically the same as 18500)

The two cells do not match in capacity, i.e. they are best used one at a time. The capacity is as specified and fairly stable even at 15A, i.e. the cell is very good at high current.

Conclusion

The battery has very good high current performance, but I am not impressed with the capacity diffence.
