Not exactly an answer, but a similar situation - I recently switched from a traditional Tripp-Lite UPS with expansion battery pack to an EcoFlow Delta 3 Max Plus. The 'Plus' models have USB-HID support and recent versions of NUT know how to talk to them. I have at least 4 times as much runtime now (using a 2kWh EcoFlow unit) and it takes less space and is silent at my load level.

There is currently a firmware bug in the Delta unit which causes it to disconnect from the USB bus after about two weeks of uptime, but I'm working with EcoFlow to get that resolved.
