Very good tracking in the discharge curves.

At 20A I stopped the test due to temperature.

This test only goes to 15A and did not trip the build in protection.
Protection will usual trip on 3 conditions: Over current, over charge and over discharge.

[size=+3]Conclusion[/size]

This is a good cell, but the build in protection do not trip on overload (It will probably trip on higher currents).
