JUNK!!! no surprise here, just had to find out for myself I guess.
got 4 today from DX 'offer' site, paid $7
charge at 1A to 4.1V, discharge at 1A to 3.0V
1st cell (2 cycles) - 36mah, 38mah
2nd cell - 3mah
3rd and 4th just under 200mah
IMaybe I'll strip the PCB and reattach to unprotecteds I have...
EDIT: Opened paypal dispute. Posted review which DX did not show. Posted in forum for sku, got sheepish and cyclist chewing on me for opening a dispute. Replied to DX communication through paypal that requested I take a video to prove the cells are bad w/ a request for them to make a video of any of the cells performing properly. Got a refund 2 days later.
Cut the pcb from the one that didn't work at all. Now it will do 250mah w/ very slow charge and 500mah discharge.
Crap - totally useless to me...except maybe at firefrackers
