InCaseOf's post in Server gracefully shutting down as soon as UPS goes on battery was marked as the answer
So, I went back to the default UPS daemon and it reported that my ups was OFFLINE which made unraid shut off.
I did a bit more digging Found this tread
Which led me to this comment
I re-installed NUT and everything is working as it should be, maybe a bug with NUT? No clue since my was detecting the UPS
Anyway, thanks for the help! Just wanted to add this here in case someone else runs into this problem
