If these two UPS units are on different power supplies then it is possible for
one to reach x minutes on battery while the other is still on wall power.

NUT provides the MINSUPPLIES declaration in upsmon.conf to handle multiple UPS
units when the setup uses status [OB] to call for a system shutdown, but if your
shutdown plan is for a time based solution, then you could use NUT utility upsrw
to set the battery.charge.low value to a high value corresponding to x minutes.
This would get around the need for an external script.
