I think my onboard charger is going bad, so I'm going to replace it.
It's a 3-bank, 10A per bank charger. Each bank is totally independent of each other. It was very advanced for its time, and even today there are few with the same features. Each bank could be set separately for four different battery types, and it had the built-in equalization/desulfation mode that could be selected per bank. It is the first version of the MinnKota MK 330.
Sorta bummed it is acting up.
Anyway....
Now I see there are some chargers that "share" power between banks. Meaning, the 20A or what ever will divide according, theoretically, to which ever battery needs the most. And, of course, there are the ones with fully dedicated banks that do not share current between them.
Anyone had both types and care to comment on if they've noticed any difference in battery life, charge times, etc.?
For better or for worse?
I have some theories of my own, but wanted to hear some other thoughts on it.
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.
