I set the offdelay option of the ups to 300s and ondelay option to 600s

René Garcia, the author of the ESXi .vib, is subscribed to this list - perhaps he has some suggestions for other settings there?

We also don't have a lot of information on the APC CS650 specifically. There is a DDL entry for the Back-UPS CS 650IE, which may be similar; however, we don't have much information on whether the various options work as expected:

Does your serial number or firmware version look similar, or completely different?

Also, after you set offdelay, is there a corresponding timer variable in the 'upsc' output? It is possible that the CS650 is using a different HID path for that timer (there are at least three in drivers/apc-hid.c).

> and here comes in my problem, whenever the battery.low condition or the upssched script calls the FSD action, everything will beging to shut down normally, except that the UPS will turn off the load in about 100 seconds (while the ESXi host still needs over a minute to shutdown and the VM has not yet called the poweroff flag).
> I am at a bit of a loss what I could even try here, the only method that seems to signal the ESXi host running the NUT slave service seems to be calling the fsd action, the offdelay settings do nothing, I tried running a shutdown.stop command which didn't do anything either. Any ideas, or is this impossible with this UPS?
