At 20A I stopped the test due to temperature.

Keeppower%2018650%203000mAh%20P1830R%20(Black)%202017-TripCurrent

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.

Conclusion

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