  • 12/24/36 volt charger QUESTION

    Posted by chawchaw on April 8, 2016 at 7:08 am

    if i currently have 2 (12v) batteries onboard for the crank and deep cycle and i use a dual bank onboard charger that reads 12/24v charger on it., and i want to move to a 24 volt trolling motor , would i need a new onboard charger , or does that 12/24 mean it can do both or is that total voltage (being 24 bc im using 2 seperate 12v batteries)
    if so would i get a 12/24/36 volt charger and assign one link to the 12 v battery and combine the other 2 links to double up on the 24volt deep cycle?

    im pretty good with electronics but im just not sure about what the charger is capable of and dont wanna harm any gear

    I am pretty sure you will need a 3 bank.charger. ea lead only puts out 12 volts

    I had the same situation one time where I went from a 12 volt trolling motor, and total of 2 batteries,1 for trolling motor,1 for cranking.And I used a 2 bank charger.Then went too a 24 volt trolling mtr.and bought a 3rd battery for the trolling mtr. But instead of buying a new 3 bank charger (which are expensive) I hooked my dual bank charger to my 2 trolling mtr.batteries and bought a much less expensive single bank charger for my cranking battery. Or yes just buy a 3 bank charger.

    Thanks guys
    So I need to buy one or the other sounds like
    Also I have a 18 ft alumacraft bass boat with a merc 75
    Is it worth moving to 24 volt 80lb thrust or should I just get a 12 volt 55 lb
    I plan on getting the motor guide xi5 possibly and will be doing alotta trolling around all day and I know how rough and windy our lake can be so I figured 24 was better

    Personally, I prefer a 24V. You can run them on lower power and they will last all day, especially if you are running your electronics on them. you will either need to buy a 3 bank charger or buy an additional one.

    I just upgraded from a 24V to a 36V 101 maxxum so had to add a battery. Not that I needed a 36V, I just found a great deal on a maxxum and wanted to get rid of my powerdrive. I have a 3 bank charger installed on board. Instead of spending the money on a 4 bank charger, I simply bought a $20 single charger and added a splitter to my extension cord and can charge them all at one time.

    i had a 12 v 55hp on my lowes 18ft boat. switch to a 24v 70 hp mk . the difference was unbeliveable i can cruise all day in the wind on high never drain batteries belpw 1/4 charge. on low the batteries will go 2 to 3 days with out charge . i think you will like the difference

    I have a separate charger for my cranking battery and have my 3 bank charger on my 3 trolling batteries.
