I recently took delivery of a Back-UPS BX700UI (though it reports itself as an XS-700U!?) to hold-over my networking equipment in case of power failures.
After configuring the network devices to interface with the UPS, connected to the router via USB, the power was interrupted, to test the performance and behaviour under failure conditions.
Putting aside the fact that the UPS was reporting over an hour of battery life while on line power, yet only achieved 22 minutes, powering only the router and switch (15W-ish), as the NAS shut down gracefully, I was disappointed to discover that I was no longer able to interface with the UPS via USB when power was restored.
Frustratingly long story short (yes, different USB cables, direct to laptop with PowerChute, etc.), I was only able to recover the USB functionality by pulling, and re-inserting, the battery jumper!! (HT to user here who experienced the same in Jan 2019)
I consider this utterly unacceptable USB behaviour from a power-assurance device! Not only did this render the network devices unable to be brought back up, on line-power restoration, but it required a fiddly manual intervention to restore functionality.
Please tell me there is a fix for this behaviour!?

Regarding the short runtime, are you sure the no-load switch-off was off? 15W is very close to what it detects as "no load". You can switch this off. Edit: Actually, if your NAS shut itself down it's normal for the UPS to power off after this. It'll give the attached server a configurable time to shut down, after that it'll turn off the load. So just set this time to be longer.
I'm not sure about the USB problem, I haven't seen this myself but I only got this unit myself yesterday.
