Not Arduino but yes all the new voltage regulators use solid state electronics to control things ....also adds to the cost of the things.
And for why not just tap the batteries......see original HMMWV all 28v...then they got an electronic transmission (14v) taped rear battery and found that it causes imbalance issues on 28v side. Lower battery never getting to full changed and draws down system. solution tap 14v from alternator to top up that lower battery and keep it charged. and now that the military has that the run with it they buy the cheaper option for every part they can 28v starter 14v lights etc.
also yes there's actually a MIL Standard for batteries less operation, its like 30min or so I don't know for certain. and think not of if it was jumped but as "Hey the battery box got hit with incoming fire and the batteries are gone does the truck still run long enough to get out of town".
