[C320-list] Voltage Regulators- New thread away from batteries

[Troy Dunn]

Jeff

Correct it doesn’t display amps, but...

 I think that the advertised simplicity, ease of set up, and accuracy of
this device potentially makes knowing those other things non issues.   In
addition to voltage this device displays the true state of charge of the
battery, and that’s the beauty of it.  If you know the real SOC....all that
other stuff doesn’t really matter.   Amphour metering through a shunt is
nice IF you know exactly how many amp hours of capacity you have in your
battery and the starting state of charge...but....you don’t actually have a
way of knowing these numbers accurately in that type of setup because
capacity is always dropping and SOC is a function of a pretty complicated
set of variables.  So....   Knowing current doesn’t actually tell the whole
story either.   Admittedly prior to this device appearing on the market,
amp metering was the best monitoring that could be bought.   This device
might truly be a game changer. Do not be fooled...this is not a volt meter.
  It is purported to be a highly sophisticated electronic device.

RC (aka Mainesail) has a really good write up on his web site.   Absolutely
worth a read.   I'm pretty much sold...I’m hoping someone who has one
chimes in before I  make the leap.
