I'm trying to charge 4 x #18650 4.2V 4.5Ah Li-Ion batteries. Like these:

i'm using this charger:
http://r.ebay.com/6hk1Op

This charger does not appear to be working. Surely my own error. When i charge some good 18650's (not full, but have at least 3V charge), i do not see any of the batteries getting charged. After a couple hours, most of the batteries DROPPED a few tenths of a volt.

What am i doing wrong? Is it a mismatch between this board and the ultra fires? Or maybe these are just fake li-ions?

THANKS!

All is possible,

Could you post a photo of your setup? It would prevent many questions about your connections and speed a result.
