So I got me a couple of birds at an auction, es4's and 2's and I see this extra battery pack on Amazon. I buy the pack anxiously awaiting to see what more I can do with them and the battery pack will not work on any of them. Is there a step or a couple of steps I have to do before I install it. Not sure if this thing was supposed to come with instructions but I have no idea what's the matter. When I install it and turn it on, it beeps and will not go does anybody know anything about it??????
