My guess is that if you sent 520, upsc would return 8 (for a revised

As you found, the ignorelb option is available to work around
limitations in the UPS shutdown logic.
I can confirm
upsrw -s battery.runtime.low=520 -w CST150UC@localhost
battery.runtime.low: 8
I also tried
upsrw -s battery.runtime.low=480 -w CST150UC@localhost
battery.runtime.low: 480
upsrw -s battery.runtime.low=540 -w CST150UC@localhost
battery.runtime.low: 28
I guess none of this makes any sense to me so maybe the ignorelb option
is the way to go unless you have a suggestion as to what value to use
with upsrw -s battery.runtime.low, lol.
This seems to work though
mcedit /etc/nut/nut.conf
[CST150UC]
driver = usbhid-ups
port = auto
ignorelb
ondelay = -1
override.battery.runtime.low = 3600
upsc CST150UC@localhost
battery.runtime.low: 3600 (system will shutdown when 60 minutes of
runtime is left)
ups.delay.start: -1 (never powers on the load, even when main power returns)
Thank you
