I'm not sure the issue is the same but.....I had a problem with the "Wait Conn" error as well. The fix was actually in the cable to the turbine. I took it out on the turbine side and reseated the plug and everything was fine. While everything appeared tight and connected properly, apparently it wasn't happy with the connection. Doing this cleared up my errors. At least it's something simple to try. I can't imagine it's the 2S pack as that's how mine is powered as well.
