I can confirm

upsrw -s battery.runtime.low=520 -w CST150UC at localhost
battery.runtime.low: 8

I also tried

upsrw -s battery.runtime.low=480 -w CST150UC at localhost
battery.runtime.low: 480

upsrw -s battery.runtime.low=540 -w CST150UC at 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 at 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
