Can I use a Lithium battery for my trolling motor?

You can use a lithium battery for trolling motor. They last longer but do cost more than deep cycle battery.

You might have often heard and used up a deep cycle 12-volt marine battery for your trolling motor but the other option for the longest run time and lifespan of your motor is the lithium battery.

You can also use a lithium battery for the betterment of your trolling motor. This can really enhance your experience with your trolling motor with an amazing backup. They have many advantageous features over conventional wet lead-acid, AGM, and the sealed gel marine deep cycle batteries. And the most considerable thing is its long-lasting power, that is just amazing.


To prove it’s a long-lasting feature, we can even take an example: if a 36-volt motor is to sun three 12-volt marine batteries in a series to achieve 36volts but at the same side three 100amp hour lithium batteries in a series will power a trolling motor running at the same speed but twice as long as a series of 100 AH marine batteries could do.

Moreover, lithium batteries do not lose voltage as they are trained to make the trolling motor lose the thrust as in conventional marine batteries. Once the battery life is used up to 50% then the conventional marine batteries can no longer produce the voltage needed by the motor.

Although holding their 50% of capacity as soon as the trolling motor is concerned, they are off. Additionally when these conventional batteries are drained to 50% then it can never come back to its full capacity.

Whereas talking about lithium batteries, they do not lose voltage as they are drawn down and also can be drained to nearly 100 percent before the voltage drops. This is how it assists to keep the motor at its full strength all the time. The more interesting fact about the lithium battery is that it differs no harm although it is fully discharged and also can gain the same strength again.


It can also be recharged around five or more times than other deep cycle batteries. Lithium batteries are also the most lightweight since they weigh half than a conventional deep cycle marine battery and get charged in just half the time.

Only the drawback with lithium batteries is the high cost or say it’s expensive in nature. If you want to buy a perfect fit for your motor then you have to pay around $1000 to $1200 for each that means to power your 46-volt trolling motor you might have to pay almost $3600. Now there are several companies in the market providing the best lithium deep cycle marine batteries in the low prices even.


There are several marine lithium batteries in the market with their own major importance as well as characteristics. Lithium batteries maximize the potential up to 100% that simply means that you can use your fill battery capacity to power your vessel.

Like LPB marine lithium batteries is the one that comes with a proper battery management system to prevent overcharging and other power malfunctions. It is also one of the safest batteries available. The lithium batteries are 70% lighter than the standard AGM and the lead-acid battery.

The lightweight helps in the increased overall speed on water, improved acceleration, and more efficient fuel consumption. These are the reasons why they are considered the best than other conventional marine batteries. So, paying for such valuable products does not seem to be so expensive. The features are totally worth it and even reliable for any kind of trolling motors. 


Thus, you can probably use the lithium battery in your trolling motors since it has a lot of advantages over the other conventional deep cycle batteries and even if you look at the features of the lithium batteries then the cost is not as high. It is considerable for its amazing features which are surely worth it. It has all the features which are highly required by the professionals and other boat lovers.

It will provide you gull power with less charging time, low maintenance required, lightweight, more efficient, suitable for all motor types, etc. So, you must once try this new version.
