So trying to understand, the 2s lipo supplied by Wren is for the fuel pump? So does the FADEC use power from the receiver at all? I'm asking because I have my RX pack plugged directly into my receiver with HV servos and just want to be sure that's ok...

I think the fadec does use some power from the receiver pack as you can do setup without having the turbine battery connected. It is possible that it is taking power from the throttle lead. I'm not sure if it is either/or situation. I know you need the second battery to handle the fuel pump and the starter.

Correct, the ECU can get power from either side.

It can also take 2s power directly, no problem.
