Official specifications:

This is a fairly high capacity and high current cell.

















Oops, the two batteries do not match in capacity, this means never use them in series. One of the cells is significantly below rated capacity.






















Conclusion

I am not happy about the difference in capacity between the batteries and the very precise capacity rating do not really match the batteries.
