Regular high capacity cells.











The discharge curves has very good tracking and nearly constant capacity up to 7A. At 15A discharge I had to stop early due to temperature.




Even at 7A the cells do get warm.



They did handle the 10A discharge, but was very close to trip on my over temperature cut-out. In regular use I will prefer not to do 10A continuous discharges.



No safe way to 15A continuous discharge on these cells.















Conclusion

There is not much to say about this cell, it looks like a very good cell for most usage, but it is not for really high current jobs.

Henrik, a thourough review, as always. Thank you!

It seems that the vaping-scene is not always a breeding-ground for the next heavyweight contender :wink:
