Can we use lithium ion batteries in these??

Anybody know why the portable power station companies aren't making computer UPS? It's a high priced market.

Is it that hard to have fast switching times? If so maybe a hybrid solution where a smaller 12v lead acid battery handles the switch load till the Lithium Ion battery circuits take over?

I see they are available and reviews have been good so far...

1000VA = $180
1500VA = $340
2000VA = $640
But at those prices you might as well get a portable power station for the 1500VA+

So.. I had this idea and have an ecoflow 2 MAX in front of my UPS's the problem is that the ecoflow doesn't think lower voltages are a "problem" and won't switch but the UPS will because they are pure sine wave models. I've noticed when really big lightening strikes happen the ecoflow won't do anything but the batteries will switch for a few seconds then switch off again. I suppose I could turn down the sensitive or completely turn it off but my PSU is a 1600w psu serving a server so I "assume" it is fairly sensitive to voltage droop. I've never like tested that but I honestly don't want to mess up my server/data either.

I should mention in "full power outage" situations though the ecoflow shined heavily and powered my server for nearly 2 hours. The bad thing about THAT instance was that the power was off so long I had to power off anyways because the heat generation..

That's why I currently do a "hybrid" solution where a lead-acid UPS does it's backup as well as shutting down equpment (like a NAS) via USB. For network equipment when runtime dwindles to 5 minutes remaining (Because I don't know when power will be back) I unplug it from the wall and into a LiFEPO4 portable power station knowing I'm getting AC/DC conversion losses but it's still uninterruptible.

I have had many different types of cyberpower units over the last decades. Most have been the 1500VA with dual batteries. All typically failed within 4 years. In most cases, changing the batteries work BUT in a few instances, it's been the mother board.

some of them do switch fast enough actually.

They have no incentive to innovate as long as people keep buying their outdated solutions. So lots of people have resorted to hybrid approaches you're thinking about. My method is to use large LPF power stations like Ecoflow Delta 2 as bulk runtime storage, then daisy-chain a small traditional UPS after that to protect my sensitive equipment. I also optionally add a surge protector at the wall outlet since the power stations don't have those.
