I did think of that, I even have the inverter already...

...but I was concerned that the inefficiencies of converting through
AC would make this a losing proposition?

Anyone have any idea how much I'd be down? I couldn't begin to guess
if it'd be a couple percent, or 30%... :/

And unfortunately the testing is a bit unwieldy, what with my 24 hour
runtime target, and I don't want to over-deplete a battery just to get
a baseline, if I can help it. :/
