[RE-wrenches] UL/CSA listed battery monitor?

[bob at midnitesolar.com]

Just to clarify, MidNite has two (2) battery monitors....  Sort of...

The  MNBCM that Tom referred to is a shunt-less voltage monitor that 
lets you know when
the battery has not received an Absorb charge cycle for 1 week and 2 
weeks.  It also has
somewhat of a voltage meter.  It is purely based on battery voltage and 
looks for the rise
in voltage for an accumulated of around 2 hours or so...  It has a 
semi-circle of LEDs on it.

Then the Whizbang Junior is a 500A @ 50 mV shunt tack-on circuit board 
that connects to
the MidNite Classic or Kid charge controllers that calculates State Of 
Charge based on
Amp-Hours in and out of the bank.

Thanks,
boB
