How to charge a trolling motor battery from the outboard motor. As mentioned above there are two different ways to use your outboard motor to charge your trolling motor battery. The first involves upgrading your outboard motor by installing a regulatorrectifier. The second simply uses a battery combiner.

Lets start by looking at how to upgrade your outboard motor. Just connect a COMBINER 100 between the starting battery and the trolling battery. Whenever the outboard engine is running the combiner will share the charging output with the trolling battery.

When the engine is off the trolling battery is separated from the starting battery and will not accidentally discharge. To charge a trolling battery in an outboard motor you need to identify the power ratios of the battery first. Then you need to pick a proper power box that will charge the battery in any condition.

Then pick a proper generator. Automobile and boat generators will do good. If you want to connect the trolling battery to the outboard motor you need to use a combiner that will connect between the trolling battery and the starting battery.

If the outboard engine will be running its the role of the combiner to share charging output together with your trolling battery. In case your engine is OFF you will find that trolling battery separate with starting battery so you dont expect it to. July 12 2006 at 126 pm 459938.

I lived in an apartment for a while that didnt have electricity in the garage and the 2 wheel dolly is the only way to go. I attached a plastic battery box to it and rolled it back and forth for charging. But in this case I think Id.

One of the ways to charge the trolling motor batteries is through the outboard motor. You may find that your outboard motor is already set up to charge your battery. In case this is not done you have to convert it for it to be able to do so.

By installing a regulatorrectifier this may be possible. There are various methods to charge trolling motor batteries ranging from the solar method using the outboard engine and charging the batteries on the lake. Most importantly choosing the right kind of charger for your trolling motor battery goes a long way in maintaining your battery health.

Charging Batteries Using Solar Power. A trolling motor can be charge with solar power. A solar panel and other equipment are needed to do this.

Simply position the solar panel on the boat. A higher position is better to catch more sun rays. A boost converter is useful to take low voltage and convert it.

Theyre easy to install they mount in your boat and stay there and connect to your starting battery and your trolling batteries. The alternator on your outboard chargers the trolling batteries. Positives are that they are convenient not too expensive and will charge your trolling batteries.

However this is perfectly adequate for gentle battery charging. Ideally the circuit should be followed by a voltage regulator to keep the voltage down to around 144V but lead-acid batteries are tolerant of quite high voltages when charging so I just keep an eye on my voltmeter and switch from A to B if the voltage gets uncomfortably high say over 16V. How to Charge a Trolling Motor Battery.

Dos and Donts Source. One must know how to charge a trolling motor battery by keeping in mind the type of charger and battery. Separate the battery from the electrical supply.

It must be clean and dry. Put on protective gears. The best way to charge your batteries while on the lake is an alternator charger connected to your main motor.

How to charge a trolling motor battery from the outboard motor is simple using an alternator charger. Minn Kota makes a series of DC alternator chargers and. You can use an on-board outboard or solar-powered charger to ensure an uninterrupted source of power during your fishing ventures.

AGM batteries can power up very fast sometimes within 2 hours. However overcharging can leave a permanent mark on your AGM battery so always be cautious while charging. Sealed Gel Batteries usually comes along with a customized charger.

Connect the charger with the battery and charge it until it reaches 144V to 147V on a 12V battery. Meanwhile a 24-volt motor will need a double bank charger. Keep on reading to know how to charge a 24v trolling motor system.

Place The Battery In A Safe Location. Unplug the battery from the trolling motor then take the battery to a dry and safe place. For your safety you need to make sure the battery is not connecting to any electronic devices.

Does my outboard charge my battery. You dont have to guess on the alternator. Put a voltmeter on the engine battery with it off and read the voltage.

Turn on the engine and run at moderate rpms. Read the voltage again. If it is the same or slightly less you dont have charge capability.

If it is up around 145 v you are good to go. How to Solar Charge a Trolling Motor Battery. The process is close but not exactly the same for a solar charger.

1Make sure your solar panel is positioned well to get the most light. 2Disconnect the battery from the motor and then attach your charger. Remember red goes to red first then black to black.

If you intend to charge the batteries from a 12 volt tap on the generator make darned sure you take a fire extinguisher with you. You cannot charge a series string of 12 volt batteries from a singe 12 volt source. You would have to charge each battery individually via some sort of switching system.

A Float Charger will recharge batteries in three distinct stages. When you first plug in your Minn Kota onboard charger your batteries will enter the Bulk Charging phase when the highest charge voltage and current will be applied to restore battery charge typically up to a point of 80 of the battery. On-board chargers are permanently installed wired directly to the batteries and can be left in-place between charges simply connect to an AC power source to charge.

DC chargers connect to the boats alternator and charge the batteries when the outboard motor is running instead of using AC power. For an outboard alternator the smaller the engine is the less it is going to charge. Vice Versa the larger the outboard horsepower the more electricity it will be able to produce.

Also understand that what type of battery is in the boat matters as well. A 15 HP engine on an 11 boat doesnt need to have a huge battery. Most outboard motors even those without an electrical starter can charge a battery just like your cars motor can charge its battery.

Large displacement outboard motors do this as a rule. The major components needed are. Generator coils that create electrical current unregulated AC from the motors rotation.

Regulatorrectifier to convert the coil output into regulated DC current suitable for charging the battery. Lets assume you have 100 amp-hour batteries discharged 50 by trolling motor use. It will take at least 150 amp-hours at 12 volts to recharge all three.

If the Verado can push 35 amps to charge those batteries it will take a minimum of 4 hours 20 minutes to fully recharge the batteries. How to connect a 12 Volt trolling motor and circuit breaker to your battery. AGM or Lithium batteries are the most recommended battery options for electric t.
