I saw a lot of these in my usual surplus catalogs but producing 48v from
batteries of a sufficient amperage is a bulky proposition. I envision a
small cordura camera bag filled with two surplus 12v 7ah lead acid batteries
(in parallel) and some switching gear for the scope and the PC.
I also looked at some of the mobile MP3 projects but the most suitable
solution was $150 and didn't have the right amperage ratings.
I don't know...maybe I'm looking for something that really doesn't exist. I
really wanted to avoid building my own supply, though.
