I know photogs use battery packs to supply power to their various devices,
like strobes. I got to thinking about adapting one possibly to an entirely
different application, but I need to know what their electrical output is in
volts (given they power things like strobes that are battery-powered, I'm
assuming DC).

In case you're wondering what that "entirely differently application" is,
it's model railroading, generally HO (3.5mm = 1'0", or 1:87.1), or others.

Different packs provide different voltages. Depends on the device. I'd
forget the idea unless you're looking for something ready built and
portable. Anything labeled photographic is relatively expensive.

You can build a 12V system pretty cheaply. Batteries and chargers
are common. So are 12V devices. Little while ago I bought a 12V 7amp hour
sealed battery for not much more then $10 US. OTOH I've got a flash battery
pack. 7.2V. Over $60 plus the cost for the charger. I'm sure it's not even
close in power to the 12v battery I bought.
