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.


This cell has a decent performance for the capacity and current.
