Good morning, port. The yellow thing is the cover for the 8-post bussbar.

I just checked my batteries, and even though the trailer is plugged in, battery voltage is 12.4 volts. I DON’T GET IT! I’ve double checked everything, every wire, there is nothing on in the trailer, and yet the SOC rarely gets above 60 and voltage is never consistent. To my way of thinking, plugged in with nothing on, the SOC should be 100% and voltage 12.8 ~ 13.0. I am getting ready to read my books again, for the fourth time.

clev,
One item that may be confusing you is the AH capacity--when you series 6-volts to 12-volts, it does not double the AHs. You still only have the AH of one 6 volt battery when series as 12-volts. I have 4x300AH Lifelines, but in series/parallel, so don't have 1200AH, only 600. At least I think that is right...
Joe

Yes, Joe, you are correct, and I am aware. I have six 6-volt 220 a/h life lines wired in series/parallel for a total of 660 a/h. New, just purchased last month. Do you have, or are you familiar with the ME-RC controller?

clev,
Yes, have the ME-RC but definitely not familiar with its operation. Barely can remember when to switch from inverter to shore power thru trailer.

Wish I knew more to help you, maybe Chad will take note.

In your pics, I only see 2 of the six batts--are the other four on both sides of the trailer? If so, maybe some glitch in how you have them seriesed/paralleled?

I’ve gotten familiar thru use. I’m reading the books again and been thru the menu a dozen times. I’m now changing Final from ‘Multi’ to ‘float’ and battery type from ‘custom’ to AGM 1.

Sometimes the BMK “brain” needs to be reset in order to start calculating things properly when new stuff is added to the system. Also, every negative cable in your system needs to be on the load side of the BMK shunt. There should be no negative cables for any loads connected to any of the batteries anywhere. If any of your house loads, including your 12 volt power panel, Jack’s, slides, etc are connected directly to the batteries in the door side battery compartment (as DRV does from the factory), then the power they are drawing is not correctly calculated by the BMK.

Thank you, Chad. That’s the job that I just finished. I had about 7 positive and negative cables connected directly to the last and first batteries, respectively, and have moved all to positive and negative bus bars. The bus bars are attached directly to the lugs on the inverter. I modified some settings yesterday afternoon and will check results after breakfast.
