How to Wire Two 12 Volt Batteries to Make 24 Volts

The Blue Seas Add-A-Battery switch is intended to connect two volt batteries together, not to connect a volt battery to a volt series string of two volt batteries. I’m doing some research on this. Tom posted The drawback with this approach is only two of the batteries will get charged by the motor. The third battery is never charged. See Charging Three Batteries In Separated 12 and volt Systems for the links to the only two products I could find that accomplish this. Jefecinco posted It appears the Dual Pro may be what’s required.

How to Hook Up a Motorguide Trolling Motor 12/24 Volt System?

First Light Are you saying that your engines have 24v starters? If you have 24V starters???? You may be able to get enough juice by using the jump battery on one. Are you sure the batteries aren’t in parallel yielding 12V but more amps? Originally Posted by dawgmode Post yes they are 24v starters and the 2 12v batteries that are wired to 24v are dead so i want to know if it is possible to hook up another battery to jump it You would need 2 batteries and a 3rd wire to connect the positive of 1 battery to the negative of the other.

So now your 2 jump batteries are in series to produce 24V.

May 08,  · 12 volt trolling motor wiring Im going to go to a 2 battery setup to run my 12v trolling motor to double the capacity. I know how to hook up the batteries in parallel.

It is considered as an ideal battery for boats with trolling motors like Sevylor, Minn Kota, Cobra etc. Its physical features and functions are given below in points: It can also be accessorized in a way, to make one of the good trolling motor battery kits. This structure is the key reason behind its good performance and life for application, which involves cyclic nature of float.

It maintains this performance even after many repeated discharges. A charger is recommended for better use of this battery. There is no provisional need to worry about adding water in the tanks or to see the gravity rate of the electrolyte present. They undergo a very special kind of treatment during their manufacturing process, which makes them reliable and strong.

This is also the reason why it provides more performance than other products with lead and tin plates.

MERGE exists and is an alternate of. Merge this question into Split and merge into it SAVE In Electronics Engineering , Boats and Watercraft To get 24v from two 12v batteries you just link between ones positive and the others negative then connect your motor to the spare terminals, but your 12v charging system will not charge them and any 12v equipment connected to them will burn out!

Also, it not safe or in any way good practice just to put both of the charger cables directly onto the battery terminals.

Boats rigged with volt wiring will work with motors that displace up to 80 pounds of thrust; the maximum thrust for volt systems is pounds. Brown said it is always a good idea to consider the water conditions in which a boat will be used when making the choice between trolling motor.

Rolls batteries www. It’s not good for them to sit discharged. Proper care will significantly improve the battery life. Failure to recharge lead-acid batteries within hours is the leading cause of premature battery failure. A battery selector switch as applied in a bay or flats boat is a VERY useful tool that assures redundancy as well as “peace of mind” for the vessel’s owner. A high quality battery selector switch should have a sufficient capacity power rating to safely handle the 12vdc electrical power required.

This switch MUST also have “bridged” internally sealed contacts allowing it to safely be switched from one battery to both batteries then to the second battery without any interruption of supplied 12vdc power. The Blue Sea brand is my favorite based on personal experience. Quest and Cole Hersee also offer quality selector switches. This set up utilizes both a 12 vdc system for general cranking and accessory use as well as a 24 vdc system for the 80 Minn Kota trolling motor.

This is a VERY efficient system. Plus it is connected in series with the third battery to supply 24 vdc trolling motor power.

Altering boat wiring should be completed by a qualified marine technician. The following specifications are for general guidelines only: These guidelines apply to general rigging to support your Minn Kota Motor. Powering multiple motors or additional electrical devices from the same power circuit may impact the recommended conductor gauge and circuit breaker size.

If you are using wire longer than that provided with your unit, follow the conductor gauge and circuit breaker sizing table below. If your total conductor length is more than 50 feet we recommend that you contact a qualified marine technician.

The Watersnake T18s ASP motor arrived a few weeks ago but due to floods in SC I was forced to wait to try it out. I easily rigged a mount on my Native Ultimate ’ Kayak. and added an Ever start deep cycle marine battery I picked up at Walmart for $

Just seems like yesterday. Not that I have all the answers, but over these past years I have learned some things the hard way. Like many of you, I’ve paid my stupid tax. I’ve earned my sign. Sometimes trial and error can be a hard teacher. I hope this article will help some younger folks avoid some of this when it comes to being properly prepared when you reach the lake. I guess I’m showing my age when I begin to quote old sayings like the title of this article.

For those of you that are considerably younger than me this old saying simply means your in a world of hurt with no immediate help in sight.

If you have a boat and are looking to harvest IFQ, or if you have or need deck gear, nets, electronics, etc. We can include an appropriate photo as well. Photos should be sent in jpeg format.

Use volt batteries to run a volt and volt devices. For example, a boat may have a volt starter for the main engine and a volt trolling motor. By wiring a pair of 12 volt batteries in series, you can use the same batteries to perform two different tasks.

May 11, Got a question about the wiring on a MotorGuide Pro 70 series 24 volt only trolling motor from the foot pedal to the receptacle plug on my front panel. This last Saturday was out fishing and decided to cross the lake using the trolling motor to discharge the batteries which most of the time they are short cycled and never get completely run down which can affect the battery life.

After about 5 mins or so of running in Rabbit ;- high speed, the wires burnt melted into about an inch from the plug. The smoke made me think that the boat was on fire, unplugged the trolling motor and it quit but it had burnt it completely off. Has anyone else experienced this problem?? I checked the screw terminals on what was left on the plug and they were tight so I am at a loss of what caused it other than too small of wire between the foot pedal and the plug which is 10 gauge and should be good for a 30 amp draw Called Marine repair but they did not have a real answer for me So curiosity has got me to wondering if anyone else had this problem and if any one has found out why these wires burn if the trolling motor is ran at a constant high speed???

I have e-mailed MotorGuide also..

The trolling motor is 24 volt motor. Plotman posted Does that mean you replace it and it melts again? Does you have to try to use the motor for it to melt, or just plug it in.

The trolling motor itself has almost no maintenance, you just plug it in and go. The Minn Kota endura 50 that I had, was a 41 amp motor, and I had a amp hour battery. Many people suggest only draining a battery half way, so that is 60 usable amp hours / 41 = hours usefull run time.

The Hummer Knowledge Base volt and volt Sytems: Two 12v batteries won’t give you 24v. Your Hummer already has 2 12v batteries in it and it’s still a 12v system right?

Can I cut the length of the MKR and MKR trolling motor plug wires provided for my installation? Yes you can trim the length of the wires on the connectors for your application if needed. Be sure to cut and strip the wire ends the same as they are before cutting, and to apply the extra 8AWG ferrules provided before inserting into the splicer.

Batteries achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage potential to derive at the total terminal voltage. Parallel connection attains higher capacity by adding up the total ampere-hour Ah. Some packs may consist of a combination of series and parallel connections. Laptop batteries commonly have four 3. Such a configuration is called 4s2p, meaning four cells in series and two in parallel.

Insulating foil between the cells prevents the conductive metallic skin from causing an electrical short. Most battery chemistries lend themselves to series and parallel connection. It is important to use the same battery type with equal voltage and capacity Ah and never to mix different makes and sizes. A weaker cell would cause an imbalance. This is especially critical in a series configuration because a battery is only as strong as the weakest link in the chain. An analogy is a chain in which the links represent the cells of a battery connected in series Figure 1.
