Wireless 12v Battery Monitor/Voltmeter?
Does anyone use a wireless battery monitor while dry camping? The ridiculous wired one that was installed on my TT with the standard four red dot lights is pretty inaccurate. I see THIS ONE from...

Hi,
I don't think it. I know it. Almost all battery capacity devices require you to set the amp-hour value of the capacity.
However, capacity is a "moveable feast". I.E. a battery at -30 has a heck of a lot less capacity than one at 25 C.
A battery that is 5 years old may almost certainly have a different capacity than a brand spanking new one.
A battery that has had 25 cycles to 50% may have greater capacity than a brand new one.
How is the gauge going to "take care" of all those factors?
The Victron gauge is certainly better than the trimetric (for example), but you still have to guess at capacity.

With respect,
Amp-hour counters don't give an accurate level. They are better than a volt meter.
