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

The Midnite battery monitor requires a shunt, it piggybacks onto that shunt.

    Look at either the BlueSky IPM Pro Remote with shunt or the
    Schneider Battery monitor. The MidNite Battery monitor is more
    basic as it has no shunt

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

    I have a client who needs a monitoring system for a 48V nominal
    NiCad battery bank on a boat. It's 4 parallel strings of 6V
    batteries. (Not ideal, I know) It's a passenger boat in Canada so
    all electrical devices need to be UL/CSA listed. None of the
    Bogart Engineering monitors are listed.

    Any suggestions appreciated.

    Thanks!
