Official specifications:

This 26650 cell is fairly low capacity, but high current.











The discharge curves looks good, it can deliver up to 20A with nearly constant capacity.



















Conclusion

This looks like a fairly good battery for high current application, but capacity is fairly low by todays standard.

Thank you for this review Henrik. It demonstrates that not all xxFire batteries are total crxx.
And if this fairly low capacity battery has a fairly low price, things fall into their right perspective.
