Plug the battery and the servos into the receiver it should be fine and it works that way. The bec will plug in and work the same way but you will be better off with a separate battery. The bec like Castle Creations say 10 amps but it will handle an instant amp draw of that but not a continuous and the continuous rating goes down the higher voltage you put into it. I had a similar issue with my 4WD cat tractor I was only trying to run one high torque 1/4 scale servo and Castle Creations bec would not do it but a good receiver battery would.
