We have one challenge in that one of the batteries is on the starboard side of the engine and the other 3 are next to each other on the port. Reading some of the articles it sounds like this could create a problem due to different cable lengths between the bank's batteries. Is this a concern?
Is there a way around this issue or can it only be achieved by placing all the batteries next to each other and connecting them in parallel with the +ve feed at one end and the -ve feed at the other?
I assume the battery monitor should then be wired into the same feeds?
