I'm not that familiar with Unbutu, but since you're using a fairly recent NUT version, my guess is that the problem is in the Unbutu halt script and/or in the fact that you're no longer able to talk to the UPS at that time. Typically, neat the end of it, there should be a call to 'upsdrvctl shutdown' or a callback to the script that is used for starting and stopping NUT. What should happen when the power goes out and the batteries are low, is that upsmon creates a flag (POWERDOWNFLAG in upsmon.conf) and then the system is shutdown (SHUTDOWNCMD in upsmon.conf). Near the end of the halt script of your system (when filesystems have been unmounted or remounted read-only) you should check for the POWERDOWNFLAG and if it exists, 'upsdrvctl shutdown' should be called. Note that in order for this to work, you need (read-only) access to the directory where the NUT drivers are located and also to the USB subystem. If the latter has been unmounted, NUT won't be able to instruct your UPS to shutdown.
