The Fortron site https://energy.fsp-europe.com/uninterruptible-power-supply/ has
no mention of these references. I wonder where blazer_usb found them?

If you unplug the UPS from the wall, and run it down, maybe with a dummy load,
do you see OB, LB, other statuses?

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.
