A 20650 cell, this means slightly larger diameter than 18650, but same length. This cell is a high current cell with good capacity.











The discharge curves looks nice, nearly constant capacity at any current.





At high current the cell do get warm, here I had to stop the discharge due to temperature.















[size=+3]Conclusion[/size]

This is a good high current cell with fairly decent capacity, in performance it is close to the best 18650 cells.
