This is a LiIon 26650 cell, i.e. a fairly large cell and it also has more capacity than smaller cells.

The two cells do not match very well, they cell can deliver the rated current.

Conclusion

I am not very impressed by these cells, they do not match and get fairly warm at "high" current. They do have a small capacity advantage over 21700 cells.
