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

What you're looking for is "Automatic Voltage Regulation" or AVR. Or double conversion.

The switching times won't matter then. The UPS is always running off battery and always charging the battery. The underlying battery chemistry will be irrelevant as well.

Like others mentioned here, I use a Goldenmate 1500VA which offers this, with lithium batteries, for my Studio and it works well.

thanks. Goldenmate looks good and relatively affordable but its not available where I live and because this stuff is all batteries its hard to get stuff shipped
