Battery Monitor issues

Dcline

My battery monitor says 3% and my Midnight says 85%. Based on my usage history the 85% is normal. I had issues with this battery monitor on another system so I moved to my second system to see if it acted the same and it does. I am leaning to it being a bad monitor. 

Thoughts?

Well the Midnite charge controller is in BULK and at 51.1 volts, So I have a lot of thoughts.

You haven't told us about your system, so we would need to know more.

What type of battery bank? Size and type?
Do you have a whiz bang Jr connected to the Midnite charge controller and if so did you enter the capacity of your battery bank correctly.

I'd say the only way for the Midnite Classic to be correct is if you have a under sized lithium battery bank.

With Lead acid battery bank charging at 700 watts in bulk assuming no load, You might well be below 50% of capacity.

Of course like this response "Crap data in" - "crap data out!"

This system consists of the following. 

2-strings of 8-6 volt Fullriver DC400-6 batteries, 2 Schneider Conext XW inverters and 2-Midnight Classic chargers. As well as a conext AGS, Conext Combox, Conext SCP & Conext batteriy monitor. 

I do not have a whiz Bank Jr.

Note:

as mentioned I have swapped the battery chargers around and the issue moved along with the battery charger in question.
