Samsung INR18650-29E 2900mAh (Blue)






This cell has a rather low maximum current, to get the maximum life of the battery, but it is possible to draw high current peaks.



The cell capacity does change with load, except when the cell gets warm.
The cell has same type of discharge curves as other high capacity cells, i.e. the voltage drops all the time, it does not have a plateau.

 
















The cell is not rated for high current, but it can deliver, at least for a short time.





Conclusion

Being Samsung it is a very good cell, performance is good, but not anything special.
