First of all STOP! PKid, you need to read the instructions included with your Lipo's. Lipo's, if I'm not mistaken, require a special charger and a special charge rate or something like that. Your thinking just like I did when I frist bought Lipo's, but then I started reading the forums here on RCU just to find out what I had. I bought a Kokam charger for a person selling it in the market place and now can charge my Lipo's safely. I do monitor them through out the charge just to be on the safe side and place them in a coffee can while there charging. PLEASE read more before you hook them up and cause a problem or loose your new batteries due to miss use.
