My RV install

Here are a couple of pictures of my install. 2 banks of 12vdc of 280ah each bank.

Things are tight, but it all worked out.

I cannot tell from your pics but are you taking + and- off the same cell for each battery?

Negative should come off cell 1 (and go to BMS) and positive off cell 4. Otherwise the cell with both connections will get overworked and become out of balance.

Yes, that is how I have it.

I just have them labeled... but essentially, on the far right is negative connection for BMS' and left is positive, both banks in parallel.

Looks good! I would want a little protection of the bus bars to prevent a tool from coming into contact with them.
