This is a high capacity 18350 cell, but current is fairly limited.

The two cells match nicely and it is the highest capacity cell I have tested to data (3-2021).
Note: To see the full curve at lower currents look at the "Discharge, time" curve. The capacity can be seen in the table.

Conclusion
A few years ago the 18350 cell to a leap in capacity and current, this time it is another leap, but only in capacity and there is not high current ability in this cell.
