I’m tired of buying a new 12 V battery every 1-2 years.
I have about 4 small (rated ~ 300 W [not VA]) UPSes with 7 Ah, 12 V, maintenance free batteries.
I’m thinking about replacing them with one, powerful unit.
But the more powerful the unit, the more it costs - non-linear.
Do you have experience with some DIY solutions?
Like 12V DC to 230V AC inverter, battery charger, some UPS controller (simple relay?)?
Or maybe you have some other idea that is cheap(ish)?
I have a few cyber power 1000W/1500 VA units. They go on sale for under $150 now and then. Best price/power ratio I’ve found. The battery in one has lasted at least 6 years, other is going strong for at least 2. They’re big enough to power my 8 bay NAS for a couple hours. I don’t recommend DYI for a UPS, too unreliable.
Not only is a DIY UPS unreliable, but it could be potentially dangerous unless you are an electrician, an electrical engineer, or somebody that has extensive knowledge of both the engineering side and safety side. How many CyberPower units do you have? It’s impressive that you have enough UPS power to run a NAS for that long.
Well I did buy the last one a couple years ago so that tracks. CCC is absolutely the way to go though, it’s a must. I think I also grabbed one at Costco <$200 at one point.

I have 3 - but I get that runtime out of one of them. Depends on load, but idle the nas doesn’t draw too much.
What’s the chip in that NAS?
Quad core atom I believe
That makes a lot of sense. Great low power chip.
What is your NAS? Is it something you built or a Synology?

Ah, I thought as much because they’re really power-efficient unlike something DIY.
Where did you purchase? Camelcamelcamel shows those sub-$150 price drops on that capacity might be a couple years old, too. :-)
I’ve picked up 1350s from Woot and Costco online.
I got mine from Costco, they go on sale once or twice a year there
