Is there such a thing as a 24 volt deep cycle marine battery? Is there a 36 volt?

Question

I am thingking of purchasing an electric trolling motor for a small fishing boat. I want something that packs a punch, but the more powerful motors require 24 or 36 volts of power wich would require me to rig two or three 12 volt batteries together. It would be much more convenient if I could just get 1 big battery to take care of it but I'm not sure if deep cycle marine batteries come in 24 or 36 volts.

Answer 1

For the common boater, you'll only find 12 volt batteries in the store and Marine supply. You'll have to connect 2 - 12 volt batteries in series for 24 volt operation or 3 - 12 volt batteries for 36 volt operations. These are common for Bass boat comfigurations.

All voltages are available from any of the major and industrial battery manufacturers - but the less common the size the more expensive they are. The practical limit is the ability to handle the package size. The traditional 12 volt vehicle system has been pushed well beyond reasonable limits with alternators attempting to deliver 100 plus amps of current - by raising the voltage the current is reduced (just as was needed back with 6 V systems), reducing losses and oversize wiring (and costs - copper is expensive), so newer vehicles are fitted with 42 volt systems. Regarding trolling motors, the higher the voltage, the lower the current and the lower the system losses. Plus a large saving in copper cables!



A battery is actually a combination of individual cells connected together. The common 12 volt car battery is simply a large case, with six 2 volt cells connected in series internally, and with two external posts for connecting to the work. Combining these 12 V batteries together with additional identical batteries in series or parallel creates a single larger (in voltage potential or capacity respectively) battery as far as any circuit is concerned. Having looked into a single 24 V battery once for a tractor some years ago - it was no cheaper than two 12 V batteries, and far too heavy to lift on my own safely, so I would not recommend this option.

Yes, there are 24 volt deep cycle batteries. Most commonly used in military vessels. There is no such thing as a 36 volt though for boats and vehicles. You will need to route your battery cables up in series. Positive to negative to positive to negative.



When connecting your batteries in Series you are doubling the voltage while maintaining the same capacity rating (amp hours). This might be used in a scooter, Power Wheels kids vehicle, or other applications. Just use a jumper wire between the negative of the first battery and the positive of the second battery. Run your negative wire off of the open connector from the first battery and your positive off of the open connector on your second battery.



When connecting in Parallel (positive to negative/ positive to negative) you are doubling the capacity (amp hours) of the battery while maintaining the voltage of one of the individual batteries. This would be used in applications such as laptop batteries, some scooters, some ups backups, etc. Use a jumper wire between the positives of both batteries and another jumper wire between the negatives of both batteries. Connect your positive and negative wires to the same battery to run to your application.



You maybe able to find a 36 volt battery as a special application battery only though and I would worry about the charge life on it. Contact your local battery dealer like Interstate Batteries.

A low amperage charge (2-4 amp) is best for 8 to 12 hrs depending on current state of battery. More importantly is a charger that is rated for deep cycle/RV batteries. It will say on the ratings sticker or the instruction manual of your charger. If the boat requires a full chg to start, you may want to replace your battery with one that has more available cranking amps. Happy Boating!
