This is a low capacity 18650 cell that can handle very high current.



Very nice box for the batteries, especially if you want to carry spare batteries. The one I got include a paper with the above specifications.










This is a good looking discharge chart, the cells tracks perfectly and capacity is nearly constant up to (and probably a bit above) 30A







The battery gets warm at 30A, but could handle more current before the temperature would be a problem.















Conclusion

For people that want to play with high current, i.e. 20A, 30A or more this looks like a very interesting cell. But the price is a fairly low capacity.
