Aucooma%20IMR18650%202500mAh%20(Orange-green)-Capacity

Discharge curve tracks very nicely and keeps nearly constant capacity up to 20A.
The vertical line at the end of the curve is because I have stopped the discharge, but is still recording, i.e. it shows maximum temperature (gray line) and how much voltage the cell recovered (Red line).
