I just bought a Zippy Flightmax 2200mAh 3s1P 20C battery from HobbyKing. I have a Spektrum DX6i controller, and I was wondering if anyone could tell me whether or not this wire(_Male_Kokam_2S_10cm__(5pcs/bag"">http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9924&Product_Name=Female_JST-XH_<->_Male_Kokam_2S_10cm__(5pcs/bag)) would plug into the receiver, and if not, what cord would plug into the receiver. If anyone knows, please let me know. Thanks! :)
By the way, those who are wondering why half of it is blue, it turned that way when I added something and I'm not sure how to undo it.

Grant, the usual method of powering a receiver from a LiPo is to use a BEC (battery eliminator circuit). Most lower voltage ESC's (electronic speed control's) like you would use with a 3s LiPo have a BEC built in. When you plug the ESC into the throttle channel of the receiver you are automatically providing power to the receiver from the ESC's BEC.
Some ESC's do not have a BEC, so you need to wire in an external BEC. And some times you want an external BEC even if your ESC has one - usually because you are using a lot of servos or large servos and anticipate more current draw than the ESC's BEC can handle. Pulling a lot of current out of your ESC's BEC is a great way to overheat it.

A: Only if your goal is to let the smoke out of your receiver.
