Official specifications:
A fairly high capacity 18650 battery that can deliver a decent amount of current.
The two batteries matches nicely, the battery is fairly constant it capacity with different loads, but it gets warm at high currents and I damaged one of the batteries at 30A.
[size=+3]Conclusion[/size]
This cell has a decent performance for the capacity and current.
