A high capacity cell from one of the largest LiIon manufacturer.



 






As expected these discharge curve is tracking nearly perfectly. The cells are high capacity cell, but can deliver some current.
Because I cut the discharge at 2.8 volt, I do not get the full capacity from the cell.







The cells are rated for 10A and at 15A discharge the batteries gets very hot, on the first cell I terminated discharge at 75°C and the second cell I terminated at 85°C (The maximum allowed cell temperature is 70°C).
