I just commented on someone elseís post telling them my situation, which is similar to theirs, and I realized I may want to start my own thread asking you guys to get some better insight on the matter.
I have a bank of 7 batteries (deep cycle lead acid, Walmart brand)- 4 on the passenger side rear, placed shoulder to shoulder around the wheel well, under the bed. And then I have 3 on the driverís side, shoulder to shoulder around that wheel well (the 3 + 4 are directly across from one another). They are as far apart as the van is wide. We are using 7í of 6 gauge wire to connect the 3 on one side to the 4 on the other side of the van. The batteries arenít charging quite right, and we think either the smaller gauge wiring and/or the distance between the 3 & the 4 batteries may be the problem.
So question: Would upgrading the wiring between the 2 sets (the 3 + 4) to 2 gauge solve the problem of having the batteries far apart from one another? And would it help if we also upgraded the wiring to/from all battery terminals to 2 gauge? Does a bank of more than a few batteries perform better with larger wires? Do the batteries not perform as well if they are far apart from one another, regardless of what size wiring we use?
I know thatís a few questions, sorry. But I feel like 1 or all of my questions/issues may be solved by keeping all 7 batteries together? Or maybe I can keep them where they are and just upgrade the wiring to 2 gauge. I donít know. So Iím asking you awesome people for help
Thanks so much.
