Completely support your effort, but personally I'd just get a SumpJet, have it professionally installed, and call it a day. Our house has one and it's pretty neat.

Linked battery provides 75AH (not sure what "total reserve capacity of 155 minutes" means)
That's 8 hours before converting losses and the inverter says 88% efficiency =7 hours
(I think I did that right?)

I'm not entirely sure but I remember the last time I looked into a DIY battery backup appliance there were all sorts of red flags like where to store the battery, what kind of battery it was, how the terminals were exposed, whether it's considered part of a permanent or temporary house fixture, etc. There's code to be followed, unfortunately.I forgot to mention it in my first post, but I already have that exact water-powered backup pump. It can't keep up with heavy rain.
Regarding code, running a pump from an inverter sounds pretty mundane. What makes you think it would be frowned upon?

Plus, I already have a hacked together setup with a $15 800gph aquarium pump that I can use to get water out a window while powered by a computer UPS if I need to buy some time.

I guess, but i would try to build a battery voltage cutoff into the systemv either way. It might be more expensive but any battery drained to 0 is going to take a hit, and I would expect this to sit idle for years without maintenance.
