I am wondering if anyone could help me out with adding an external battery pack the BAT slot on a Traxxas 2215 receiver. My ESC has a 5 volt BEC and I want more voltage for the servo. I have searched and Googled for this information but haven't found anything. The BAT slot has 3 pins but im thinking that I would only have to hook up to 2 of them. I don't know which ones are POS and NEG. Can anyone link me up to a diagram of the pinout for this?:?

2215 receiver with external battery pack

look at how the servos are plugged in. The middle wire is red, and there will be a black and a white (or yellow or orange) wire too. The black is negative, the red is positive, the white is signal pulse. The white should be towards the inside of the reciever, the black should be by the edge of the reciever case. Make sense?
No problem bro. Anytime.
