Any inexpensive backup power unit from a recognized brand will do. There is no
need to overthinkig it if you don't want to. The cool thing of an Uninterrupted
Power Supply from a recognized manufacturer is you can get one the RPi can talk
to over USB (or whatever), so the RPi will be aware of the stat of the battery
and shutdown if it gets dangerously low.

Production servers hooked to complex power systems are able to send you an
email to your smartphone if power goes out, or if battery gets dangerously low
etc. because of this reason.

Building one yourself? I have never done it but it looks quite doable. Keep in
mind that starting an electrical fire or spilling the contents of your homemade
battery on your carpet sucks. I'd use a self-made unit for the fun of it in a
safe environment but I would not leave it running 24/7 so happily.
