Lots of posts on the addition of 12v external power source. Most say bypass the battery and master switch. Why is this if the input power from the external (battery) is equal to or greater than the voltage on the airplane's battery? is there a chance of damage to the system? In addition to battery charging, I'd like to fire up my Dynons and do some hangar flying since I'm new to these avionics.
