I've attached a fixed version of the Queen Beacon widget that should work whether or not the battery temp module is loaded. The caveat is that if the battery temp module is loaded it will use the voltage provided by that* which differs from the regular value.

*Probably, it uses the first value which in my tests was the value from the bq27x00_battery module, but I don't know if the order is fixed, for all I know it could change depending on conditions at boot time. If the order is fixed I can easily mod it to use the second value, but then it wouldn't work when the module wasn't loaded because there wouldn't be a second value, then it would require some added logic (and complexity) to determine what to do, but I could easily mod it so it used either the highest (or lowest) of the two values if anyone wants.

EDIT: Fixed attachment, so the checksum should be correct for import into Queen Beecon
