Best bang for the buck battery backup (self.selfhosted)

submitted 1 year ago by mrtoast72 to c/selfhosted

Like the title implies, I’m trying to figure out where to pickup cheap used or new battery backups (ups) in Canada.

I have a couple of small servers I run, so around 1000+ watts should be good.

If I have to replace the battery inside, that’s not a problem, there is a battery place inside my city that offered cheap replacements for around $30.

Any suggestions help!

I've been running my stack with a pair of Cyberpower 1325 VA. All told I sit around 750 watts average use which with the two evenly balanced gives about 10 minutes runtime. Enough to shut things down (includes keeping the poe powered APs up to access things via laptop) with the NAS being configured that if the battery gets to 5 minutes runtime it will shut itself down in case something happens when I'm not around at least the main datastore won't abruptly crash.

Can find them for about $150 USD each if you look around. If your servers have front displays you should likely be able to see the draw from there, but like mentioned by another a 'kill-a-watt' is nice to calculate all those extra bits like a modem or switch that are less obvious amounts.

750w constant would be brutal for my bank account, jealous of you people with cheaper electricity costs. Costs like $0.38/kWh where I am.

I think my cost is around $0.28 so I feel your pain man.

I think it's around $0.18 here last I looked. Still not nice to the bank but not bankrupting at least. Now keeping the room cool mid-summer, that's another matter...

After having two cyberpower UPS's fail on me at critical times, I will never touch a cyberpower UPS again.
