[size=+3]UltraFire BRC26650 7800mAh (Red)[/size]
Official specifications:
Cheap super high capacity 26650, it is barely necessary to test to give a correct conclusion.
The two cells I tested have different capacity, the best can reach 2300mAh at 0.2A. They can barely deliver 7A.
Even at maximum load the temperature is not that bad.
[size=+3]Conclusion[/size]
Different capacity for the two cells, below 1/3 the rated capacity, problems delivering rated current, it is bad cells.

How is the test done and how to read the charts
How is a protected LiIon battery constructed
