Scott,

Ok.  
Since my LSI dual ignition and prop are hot direct from the battery, how about just adding plus and minus separate lines from the 2nd battery to the ignition and electric prop switches?
And, should I have Schottky diodes ... somewhere to keep the stby battery charged normally, yet isolate it in case of main battery shorts?
(Sorry for the simple questions... I'm electrically challenged.)

Terrence,
 
If you have a dual LSI ignition, you should have a backup battery for one of the ignitions.

Brent,

here's mine.  I also have my AOA vane on the wing.  Have an Odyssey battery, B&C alternator and a backup small standby alternator; and a Garmin 396 w/ its battery.
Can't think of a senario where I couldn't maintain control if I lost all electrical, except 5 vdc for the LSI ignition.
Considering adding an small backup battery in parallel, or just for ignition. 
Comments invited.
