A very high current 18650 according to the rating (35A continuous, 50A puls).

The 35A rating is optimistic, but it can do 20A. I would have like a bit better tracking at high current.

[size=+3]Conclusion[/size]

The battery is acceptable for a high current cell, but as is often the case the specifications are too optimistic.
