24 volt charging question

I need some help!

My new boat has a Minn Kota 24 volt trolling motor. I bought a 4 pin plug to wire to my 12 volt battery charger to the front of my boat thinking it would charge both batteries; not the case.

The batteries are wired together so I was only charging one battery. Needless to say I found out the hard way when the one battery was dead and the other one was full. Not a good combination for a 24 volt trolling motor.

Question: Do I need to buy a two bank chager to avoid this problem and any recommendations on chargers?

I have seen several ugly reviews about on board chargers going bad after a several month. Probably to much boucing around on the lakes.

Thanks for the help.

I use a 3 bank, 5 amp on board XPS from Bass Pro. Its made by ProMariner and haven't had any problems with it. When I get home I plug it in and forget it until time to go again. It will recharge my batteries over night.

I've used a Guest 2 bank onboard charger (10 amps per bank) for 3 years without any trouble from the charger.

I'd get a 3 bank charger. One bank for each trolling battery and one to keep the cranking battery topped off.

I also use this charger, with no problems. I think you need a three bank for sure.

My boat had this same setup when I bought it. (I think. The 4 pin plug would plug in where the trolling motor would.) It would charge both of the batteries. You could have a bad battery or wiring problems. I have an onboard charger now. Get a multi-tester and see if the charger is charging both batteries by checking the batts while the charger is on.

Thanks for everyone help.

On board charger looks like the the best solution.
