I need some help. I am upgrading, but need some advice on the installation. I now have 3 batteries, 2 for the 24v trolling motor in sequence with a jumper from the neg. on one batt to the pos. on the other batt, and 1 for starting the outboard. I have a 3 bank charger to hook up to all of the batteries. My main question is this: do I need to disconnect the jumper from the trolling motor batteries when I am charging them or can I leave it on? It just seems like there wouldn't be any charge going on if I left it on. Also, should I then make one side of the jumper a clip for easier removal? All thoughts and comments are welcome, including those saying that I'm an idiot for not knowing. Thanks!
