Nar mate, get one of these: http://www.hobbypartz.com/73p-ac680-accharger.html
That is a full-on, full-power, made-for-Lipo charger. Don't even mess around with "wall-wart" chargers, and for HEAVEN'S sake, don't use an old NiCd / NiMh charger! (unless you want to burn your house down)
That charger comes with a balance board for anything from 2S to 6S. Even comes with a USB dongle that allows you to hook the charger up to your PC for monitoring charge/discharge characteristics. Comes with a bunch of charge leads too, but if you've already picked a connector you like (Traxxas, Deans) you'll have to make one for the charger. No biggie.
