An advertisement in QST magazine caught my eye and I wonder if some one
has used something similar to this in gliders(we don't need 25 Amps at
12 Volts):

The idea is to keep the voltage supplied to your electrics constant even
if the battery voltage drops to as low as 9 Volts (in the above example).
