Official specifications:
This is a 18650 battery with good capacity rated for high current.
The discharge curves tracks nicely, but the battery gets fairly hot at high discharge currents.
[size=+3]Conclusion[/size]
The cell has good capacity (slight below 3100mAH) and good high current ability for the capacity, but the current rating is way to optimistic.
[size=+3]Notes and links[/size]
The batteries was supplied by Eizfan (Efan) for review.
