Similar to Mike's report on the CPS UPS, the HID descriptor for this device is buggy:

Logical Maximum(1)
Logical Minimum(0)
...
Report ID(5)
Usage Page(Power Device)
Usage(Voltage)
Usage(ConfigVoltage)

I think the Logical Min/Max are responsible for the battery voltages, since there are larger values in the log:

   0.240091	Report[buf]: (5 bytes) => 05 51 00 48 00
   0.240097	Path: UPS.PowerSummary.Voltage, Type: Feature, ReportID: 0x05, Offset: 0, Size: 16, Value: 1
   0.240127	Report[buf]: (5 bytes) => 05 51 00 48 00
   0.240138	Path: UPS.PowerSummary.ConfigVoltage, Type: Feature, ReportID: 0x05, Offset: 16, Size: 16, Value: 0

Does a battery voltage of 72 Volts (0x48) sound right?
