If you are thinking of a battery and inverter to 120vac, it may not work. I've tried a number of them and they crank out a lot of noise. When I run the 750w converter in my truck it puts spurs and hash across the whole band. I have been reading about 12v battery powered computers. These run directly off the battery and don't do a 12vdc to 120vac to required computer power conversion. I'd like to see one in person and check the noise generated. It would be *very* useful to have a permanently installed mobile computer in the truck. Mostly for work purposes, but running an SDR would be great. If the Perseus runs off 12vdc directly, using a UPS battery would work well. They are easy to move, don't leak and recharge easily off a common 12vdc power supply. Radio Shack sells a 12v 7amp-hour battery for about $30. Having equipment that runs right off the battery is the best. I have a yellow top Optima deep cycle as the second battery in my truck. Runs the radio and auxiliary heater. The heater is the same one that truckers use in their sleeper. Espar Airtronic D2. Keeps the truck comfortable without running the engine.
