bought these from usa seller marrsinc based out of tennessee on ebay. four for 14.99. they came shrink wrapped together and packaged in a bubble envelope along with my receipt and customer email support address. everyone who orders from this guy is happy with their orders. the batteries have nice wrapping on them and look to be quality built. checked the voltage on all four and got readings from 3.4-3.8v so no dead cells. dropped them into my dsd charger and right away noticed that don't have to be wedged into the charger like my fandyfire cells so they are obviously smaller. should be happy with these batteries especially for how much i paid for them.
I bought 12, one was dead. They are too large for my unprotected cell chargers, but no problem, have corded chargers that work great.
The cell wrap/label is a bit thin for my tastes, and is easily damaged, if care is not taken when inserting/removing in snug-fit chargers. Up to buying these cells, I used nearly new laptop battery pack salvages (24...count 'em!), and the wrapping on those cells is far superior to the tenergys'.
The price, however is a smash hit.
First cycle netted 2240 mah average charge, after discharge to 3.3v. I had 3.0 programmed into the turnigy as cutoff, but it terminated early with all batteries, for some reason, with 1A. discharge. I also charged at 1A. Will have to look into that, or break-out my pathetically expensive Bantam BC-8, which is far superior to the turnigy clone of it.
