[size=+3]Windyfire 14500 800mAh (Purple)[/size]
Official specifications:
This LiIon battery is in AA size and contains about the same energy as a AA cell, but at 3 times the voltage.
The curves are not that good, the cells has about the same capacity, but not the same voltage at higher loads.
Note: The 5A curve is outside the specifications.
[size=+3]Conclusion[/size]
This cell is a disappointment, they do work up to the rated 3A, but I do not like the difference between the cells.
