I plan on using one quick release bracket on the bow, and either using trolling motor or anchor not both at once. Both with the bracket to fit the quick release. Depending on what species I am going after I would be using one or the other. So no need to have both plugs. And it wont take up so much room up there having both units installed at the same time. So when I go after catfish in the river, or anchoring up with buddies to chill and grill, I would have the anchor. Trolling for salmon/trout or bass fishing, I would have the trolling motor up there. I am adding the trolling motor, so I didn't want to have to run another plug, because space is tight. So I think if I put 3 batteries in series, and run the + to one pin, The - to the other pin. And on the third pin just a single wire to the + on first battery that the ground comes off of from 36v series? I think it should work. But I figured there is a wealth of knowledge on this site, and someone would point me in the right direction.
