Don't know HOW many times it needs to be repeated.
When using the "idiot lights" and the "battery" button, 4 bars is NOT FULL.
It is "CHARGING"
C - G - F - L
Stands for CHARGING - GOOD - FAIR - LOW
As long as the voltage of the system is 12.7 volts or higher ( above 100% battery capacity BTW) you will get 4 BARS.
Once it STOPS CHARGING - (voltage dropping BELOW 12.7 volts) you will get 3 BARS - 3 BARS IS "GOOD"
It will stay "GOOD" until the battery drops to "FAIR" (TWO BARS) or about 50% capacity.
When it hits 1 BAR the battery is DEAD and has only enough capacity to keep that little LED lit.
When you have ONE bar it means it is LOW
I believe you might have a loose or corroded wire between the converter and your batteries. It could very well be in the power center itself.
When the wire makes contact with the converter, the idiot lights "see" more than 12.7 volts and you get 4 BARS. When you LOSE contact with the converter you see the REAL battery voltage just over 6 volts (deader than Elvis).

I've tested both house batteries and they are full. The issue is of consistency. One minute the inside indicators will show 4 bars of power and then if I drive it for a few mins, the bars will show E and the C02 low voltage indicator starts beeping. I'm baffled
