A high current and fairly low capacity 18650 cell. This is one of the few high current cells with button top.

Discharge curves looks very good up to 20A with very good tracking and nearly constant capacity, but the cell cannot handle 30A (Probably the reason it is rated for 20A).

The battery gets warm during a 20A discharge, but not too warm.

Conclusion
The cell handles 20A fine, but the capacity is a bit low by todays standards.
