Disclaimer - this is speculation on my part, i've not personally handled these cells.
These are probably a copy of the a123 systems cell of the same chemistry, though i wouldn't like say for sure. Cheap and direct from china, don't look like authorised distributors etc (ask them?).
Capacity is on the low side in this cell format, a123 list this cell at 1100mAh,
compare this to 1600mAh for aw's IMR high current cell , or 2600mAh for aw's standard Li-ion cells.
The advantages of these cells, however is the current capacity (30 amps for the a123 cells in this size, the larger 26mm diameter ones are capable of 80 amps or more
),
they also have much greater shelf life/cycle life, and can be abused beyond all measure and not die/vent/explode like the more usual lithium cell chemistries.
Whether this applies to these particular examples though....
Check out the a123 systems website if you want more info on what these should be capable of,
they are 3.3V cells so a hobby charger or specialist charger would be needed to charge them
