Here is the question. I just purchased a second trolling motor battery which I will string together in parallel with my first trolling motor battery.
I know that I will string them in parallel by hooking + on batt1 to + on batt2 and - on batt1 to - on batt2.
So here is my questions:
1. I have a single bank charger, what wiring should I use for charging? I assume that I can hook up the charger to one of the batteries and charge both as they are in parallel.
2. How should my trolling motor wiring be configured if my batteries are in parallel? Should I have the positive lead hooked to + on batt1 and negative lead hooked to - on batt2? Or can I hook up positive to + on the same battery.
Ultimately I would like to know if this configuration will work....
2 12 Volt batteries hooked in parallel. Single Bank charger hooked to one of the battery. Trolling motor hooked to other battery.
I just figured that it is easy enough to just get a 3 bank so when the boat is not in use I can keep all 3 batteries charged. I have not bough a charger yet, maybe I will give it some more thought.
Edit: After thinking this over, with the size, weight, and heat output of the charger (as well as the cost) I think it makes sense to just
buy a 2 bank charger, I have a smaller charger i can use on the starting battery when the boat is sitting at home. Forgive me, for i am a retired engineer and I have to obsess over everything...
Congrats on the motor! I think you’ll like it.
I can’t say much on the charger location but I’ve seen them under the lid in back compartments and under center rod lockers. 160 degrees is more than I expected to hear.
Curious why you’re opting for a 3 bank charger with a 24V trolling motor. Unless you don’t feel you be running you big motor enough to keep that battery up as well?
I did buy an Minnkota Ulterra, thanks for the recommendations. I had a bunch of Cabela"s bucks saved up, which helped. Now i need to
get an onboard battery charger. Where do you guys mount these things in your boat? The manufacturer I am looking at {Noco genius)
says tht their 3-bank charger will run at 160 degrees, seems like a lot of heat in an enclosed compartment? Thanks for any input on this.
Wasn't terrible at a state park beach. Antelope island maybe. I wouldn't recommend it as a beach destination tho. Figured I was there, I'm getting in it.

Any suggestions would be appreciated!
