I am planning to upgrade my VFR panel to IFR using 2 Garmin G3X displays and a Dynon D10A as a backup. I currently have 2 alternators (1-40amp and 1-20amp backup), and I will have the D10A configured with an internal battery. Since the G3X units do not have internal batteries (they only have what Garmin calls "dual isolated power inputs"), is anyone who has, or is planning to install multiple G3X displays planning to install a TCW battery backup instead of, or in addition to a backup alternator like I have now? What are others doing to sustain reliability of thier all glass IFR panels?
Thanx.
Victor
