I just really don't want to have to spend hundreds just on a powerpack!
Specifically considering this model: Repco 12V 800A Sealed AGM Battery Jump Starter - RCJS800.
Thank you in advance for any insight!

Lots of different options around. I have the same scope as you, and have been using one of these for several years with no issues. I think I got mine off ebay or from Jaycar.

Very light - it sits on the dob base and lasts at least 2-3 nights of reasonable observing time before requiring a recharge. I also occasionally plug in a secondary mirror heater and heated filter holder, although they do drain the battery a bit faster. I used to use the jump-starter battery pack, but it was a pain having to move it around as the scope slewed, and its power diminished after only a few years.
