blazer_usb reports:

The Fortron site https://energy.fsp-europe.com/uninterruptible-power-supply/ has
no mention of these references. I wonder where blazer_usb found them?
ups.status: OL
If you unplug the UPS from the wall, and run it down, maybe with a dummy load,
do you see OB, LB, other statuses?
battery.voltage.high/nominal/low: 52.00/48.0/41.60
Does the battery.voltage drop regularly as the UPS exhausts itself?
If battery.charge.low is not available, perhaps it is possible to get the same
effect by watching the voltage drop to a critical value. This needs upssched
and a custom upssched-cmd script.
The alternative is to shutdown after a fixed time in status OB. Its my
preferred solution since I live in an area with a lot of lightning strikes, but
few people seem to do it.
