A high current 18500 cell.
This is very nice discharge curves with good tracking and the cell can deliver 15A.
I did mostly run the cell empty during this test, it can deliver a lot of current, but not for long.
Good high current performance, capacity as expected in a high current cell.
This is a good cell.
