This is a high capacity LiIon 14500/AA sized cell from Ampsplus.

The two cells match nicely. The cell is rated for 1A, they handle that easily and can also handle 3A.


This looks like a good high capacity 14500 cell, it handles the rated 1A current very easily and it do not fall flat if more current is drawn.
