I'm new to this LiPo stuff too, but I will tell you what I know.

-Don't charge your battery over 1C. Meaning don't go beyond 1.2 Amps when charging that specific pack. I hear you can safely go to
-Don't charge a LiPo 3 cell pack if the voltage is 9.9v or less (3.3v per cell).
-Don't charge your 3 cell over 12.6v
-Don't discharge a battery to a level below 3v per cell under load. You can ruin your battery, and if you charge a battery that has been deeply discharged, that pack can possibly catch fire, or explode.
-And whatever you do, DO NOT short the leads of your battery. If you do place the batt in a safe place for about 15 min for observation... A nice fireworks show will most likely occur.

Best way to discard a LiPo is to discharge the battery to 3v per cell, puncture or rupture the cell, and immediately submerge in salt water. (I'm not positive on this procedure, cause I have never had to do it, maybe someone can correct me if I'm wrong.) After that it can be thrown in the trash. I know soaking in salt water is the right thing to do, i'm not so sure about puncturing the cells before so... and of course have the 3v per cell is the correct thing to do, as long as you don't intend to charge it again after doing so.

Hope this helps...

As for the prices you paid, I donno. Can't help you there.

Just remember don't charge your pack beyond 12.6. Your charger should "know" this.
