Even though the ups has usb id: 0764:0501, UPS.PowerSummary.Voltage reports 26.6 for the 24V batteries so when the 0.667 battery scale is applied that goes down to 17.7V.

Matthew, can you try the attached patch, and run the driver it with -DDDD?
Also, if anyone else has a Cyberpower UPS with the 0501 productID, I'd appreciate any additional testing.
