Just charge at no more than 1C the first few times. The key not to discharge them past 3.0 volts per cell. Also don't store them with more than 3.7 volts per cell. That's really about it, someone else will most likely chime in with more details but that's what I do to prevent premature failure and swelling. But for the most part enjoy. I'm running lipos that are over a year and half old that run about ninety percent of their original capabilities. Of course my newest lipos are more superior.
