I have a 12v battery directly powering a handful of electronic devices (router, modem, hard drives).
These vary from 0.5a~2a so I have breakers on the (+) lines into the 12v dc power plug.
I'm noticing when I charge the battery through a 120v wall charger, the battery outputs up to 14.1v and during discharge it dips to 12v.
Since I would want to keep a constant, what device would I need to keep a constant 12v output from the battery during charging and discharge?
Would this dc/dc boost be a device that could help?

edit i think this actually solves my issue
Clean 12v car power

Looks like you're making a UPS.
You will need a stepup/stepdown voltage regulator between the battery/charger and your electronics. The regulator you linked is certainly fine, but if you don't need it to be so configurable you can definitely find them cheaper.
