A 18650 high current battery with more than promised capacity.










The cells do not track perfectly but fairly good. The cell can deliver a lot of current.















Conclusion

The cell can deliver a lot of current and has a good capacity, I could have wished for a bit better tracking between the two cells, but I will call it an acceptable cell anyway.
