A low capacity cell with very high current rating.










There is some capacity difference between the cell, one of them has the rated capacity, the other more.















Conclusion

I do not like the difference between the cells. It is interesting to compare this cell to the Vapcell 2600mAh that is rated for 30A continues, that cell has the same or higher voltage and more capacity.
