Home Network UPS

[ToboRobot]

Looking for a small UPS for a small home network (Router, AP, Modem), that will keep the network up during power outages (most are under 30 minutes), so that I don't lose connection during online schooling.  My laptop has a battery, so I am just trying to keep the basic network up.  I live in a small apartment, so I think lithium instead of lead acid for smell/safety.  Hope to spend less than $250CDN, but will consider other options if they can power other devices as well.

I found this device, but it's a bit more than I want to pay... APC Smart-UPS Lithium-Ion, Short depth 500VA, 120V with SmartConnect Port - APC Canada

So I guess my questions are:

Is there a low cost Lithium Ion UPS that is commercially available for about $250, that is appropriate for a small networking board?

Is there a DIY option that is documented online that I can do my self?

Thank you!

I bought this for this exact purpose and have been happy with it. Given the rated load of my networking stuff I figured it should run for 20 ish minutes. I'm mainly trying to avoid the occasional quick power flickers that don't even reset clocks, but sometimes reset the networking gear, causing them to not reboot correclty.

I liked the fact that it had a replaceable battery as well as being inexpensive.

I have limited ability to exchange the air in a tiny apartment, and want to avoid lead-acid batteries.  

Batteries are sealed, so the chemistry doesn't make a difference, aside from Pb-acid being cheaper.

Unless I can replace the batteries with Lithium Ion?

The battery is sealed, so that's a non-issue.

I think you're a bit confused with the "sealed" aspect. The sealed lead acid batteries you'll find in a UPS pose no hazard in terms of air quality. I think you're getting them mixed up with other types of non-sealed lead acid batteries which do require venting.

I skimmed this Battery Technology for Data Centers and Network Rooms: Ventilation of Lead-Acid Batteries (schneider-electric.com)

It seems there is potentially minimal (apparently safe) off gassing in normal use and potentially if the batteries eventually fail.

The white paper says it is safe for normal office use, but this isn't just my office, I sleep a few meters away, so if there is any gas or smell, it is worth investing in a different battery tech, no just for safety but comfort (bad smells suck).

Thanks for helping me clarify this issue.

Trust me, a UPS with a SLA battery creates no smell. That article is talking about much larger batteries, as well as non-sealed varieties. I have a UPS with a sealed lead acid battery beside my bed that backs up a few things, so I'd know if it created any smell.
