This is the current set up. So replace all three at the same time. Also the bats are all the same make model. Jones trolling motors got back to me and told me to run 3 bats for the trolling 1 for engine and the rest of the electronics. So total 4 bats and use an MK-3-DC onboard alternator charger. to charge the trolling bats while I'm running hole to hole. I like this Idea

Hi all Seems to be the right place to get answers. So if you don't mind a quick question that would be great. I have a 2000 nitro CDC 911 with a 36 volt system on board, (225 EFI). I seam to be killing batteries like there going out of style. I was wondering if I have this thing wired up right. 3 batteries. all in series. with the trolling motor feeding off all three. The engine/live wells ect feeding off of one. and the third with nothing feeding off of it. The batteries in question are 2 under a year old and one purchased this year to replace one that failed. Today I go out on the water get to my fav hole and wamo my Maxim 101 at a setting of 100 thrust acting like 20 thrust. Tell tale sign that I have a problem. Take it home. Pull the batteries and hook them up to my in house 3 bank charger and 1 reading no life. This battery was bought last year. Am I doing something wrong here? Or do I have just great luck with batteries? Batteries are Interstate Marine Deep Cycles Thanks in advance.
