This battery has a fairly low current rating.

There is a significant different between the two cells, this is not very good.

Conclusion

Sibeile has been a bit unlucky with this cell, it is not anywhere near the quality of the other Sibeile cells I have tested. It can be used stand alone, but not in series.
