Another suggestion for charging lipo batteries is to get a charger that has a temp probe option.. I always velcro my temp probe onto my batts when I charge.. I have the temp cutoff set pretty low, so it will shut down the charge process if the batter get's even a little bit unhappy.. That being said.. Be careful about where you put your probe.. if you put it on the top or bottom of the battery it will only see the temp of one cell.. I think it's smarter to put it on the side of the battery so that it can get a small cross section of each cell..

Also using a lipo sack w/ Hyperion Duo for a charger (Love this charger)..
