Reply To: Battery question, need advice

It will work fine the way they are. the only thing that I would change is the black wires (Negatives) of the inverter and the charge controller on the top two batteries in your diagram. (Just swap them) This will keep the resistance of the jumpers equal on both the charge and the discharge of the battery..

By swapping the commons, this will “series” all of the jumpers (include the resistance of the jumpers) in the circuit and makes the charge/discharge more equal on all four batteries instead of pulling on one set and charging the other set directly. Leave the green and blue jumpers where they are..

Good Job!!
