Has anyone any observations on the accuracy of the voltage monitor on the RB433AH?
I see it was briefly touched on in another forum:

As I have a 433AH on a purely solar site I have been logging the voltage monitor readings every hour, and been somewhat alarmed when it has been down as low as 11.4v around dawn given that the 433's minimum voltage = 12v. So on a visit to the site I checked the batteries with a volt-meter and compared it with the log.
Volt meter = 13.25v
RB433AH = 12.7v
The RB gets its power from the batteries via PoE over around 4 metres of cat5e.
When you're dealing with 12v batteries half a volt is no small thing, so is the RB433's system health volt meter showing something other than raw voltage or is it just woefully inaccurate and unreliable?
