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).

With modern avionics/electronics you really should not need this. Modern
radios, transponders, etc. have built in switch mode power supplies that
effectively do the same as this device does, but usually more
efficiently.

Thanks, Darrell. The reason that I ask is that after flying for a few
hours with a new 9Ahr battery, the LCDs on my radio (Dittel FSG71M)
blank out when I transmit - which gets out OK. Other than the radio, I'm
only running a Cambridge 302 and an iPaq.
