Official specifications:

This is an unprotected cell, it is also used in many 2600mAh protected batteries with a added protection circuit.










Comparing it to protected version, the largest difference is output voltage with 5A load, without protection the voltage is slightly higher. For actual values use my comparator.













There is two set of curves in the above chart and they do track very well.


Conclusion

There is not much to say about this cell, it is a very good cell, just remember that it is unprotected.
