How do you keep your home servers online during powercuts? (lemmy.ml)

I live in a part of the world where powercuts are pretty frequent. 1 per day is normal. They last between 1 and 8 hours. A day without powercuts feels like a special occasion.

My machine is powered by a desktop ups which is terrible. It is only supposed to power everything for a few minutes to shutdown safely. But it is cheap and I don't know much about other affordable alternatives.

How do you folks who self host at home deal with powercuts? Any recommendations? 8 hours of uptime from a ups sounds almost impossible or totally unaffordable to me.

That's impressive! In your experience, how does the lithium battery compare to a lead acid one?

    I don’t have a good link to share, but from the research I did the difference is huge.

    LiFePO4 batteries have a higher capacity, longer lifetime, safer and higher power to weight density. Many come with built in communication, like my bluetooth connection.

    They are also expensive, but for my use case it’s much cheaper over time. I use about half a charge per day, which this battery should be able to sustain for 5-10 years. A lead acid battery would probably last months.
