Protected and USB chargeable AA sized LiIon cells and they are not over sized, this looks good.











There is a led behind the white plastic top to show when the cell is charging: red=charge, blue=done.



The two cells are well matched, they are not high current cells, but than still deliver above 6 watt.















The cells can be charged on a normal LiIon charger.





Here I am using the USB input to charge.



Conclusion

A good protected 14500 cell with the added bonus of a USB charge input.

In this case it is because the LiIon battery works as expected without any issues and because it fits 14500 size (All other protected and/or usb charged LiIon batteries I have tested is oversized)

That's it. Built-in micro-usb charger with decent amount of capacity and without growing up the length of the battery - is a jack-pot. Also I think that top positive contact with small diameter is a good thing because some twisty flashlights (such as DQG AA) have foam at the head and can't be turned on properly without that feature at the battery.
