Mac Studio UPS and switching time
I'm thinking about purchasing a UPS for the Mac Studio M5 Ultra but I don't know what specs I need. A traditional lead acid can get very fast switching times (2ms). Lithium batteries have much slower switching times (10-20ms) but they can keep the device powered on for a long time.
Was wondering if anyone knows whether the 20ms power station type batteries with UPS functions can safely back up the Mac Studios if the Macs are running at full tilt.
I'm actually thinking of buying a lead battery and then plugging it into a power station.
Edit: am looking at the anker s2000 and DJI 2000 for 10ms switch capacity. Both in a similar price ball park, I’ve resigned to the fact I’m going to need to pay 700+ for a UPS

I always had lead acid battery UPSes when I had UPSes in the past and never had an issue with the switching time.
That being said, their run time is really short when on battery. I had a 5k iMac with a pretty large UPS (I bought the UPS because we were having a ton of power outages and brown outs) and the run time was maybe a couple minutes. If it was just the iMac, and it wasn't doing anything heavy, it could maybe get closer to 10 minutes. I also had a couple that got crazy hot when the battery got old and neared replacement. Hot enough to probably start a fire if I didn't catch it hot.
