I have two powerpro batteries and wanted to add a third. My question was can the battery cable from the parallel batteries be different lengths? I read that the lengths should be the same on paralleled batteries. And is there a max distance with the wire size that is provided with the powerpro? I attached a photo of my system I’m setting up. I’d like to put a 3rd powerpro on the right side of the door(where mirror is). And run the wire under the step and to the master battery. I would have to make longer cables to reach. I contacted eg4 via email with same question but haven’t gotten any response so I figured someone here probably has an answer or have had a similar problem and a solution.
