As the total planned cost of my build climbs past another milestone, I am trying to plan all the surprisingly expensive little odds and ends that I'll need to buy (which all add up, thousands at a time!).

Does having an alternator-driven electrical system, feeding a battery which provides 12VDC power to all the (very expensive) EFIS, EMS, COM, etc systems; require a voltage regulator to prevent damage to equipment?
Or is keeping the avionics bus "off" during start and shutdown enough to mitigate the risk........?

Thanks to any electrical types who are able to help! :)
