Boat batteries are widely known among fishermen. They are available in gel, flooded, and lithium-ion varieties. Among them, the lithium battery is the most popular because of its longer-lasting power.

In order to power a 36-volt trolling motor, three 12-volt marine batteries are connected in series. A series of three best lithium batteries for trolling motors rated at 100 Amp Hours (AH) can supply 36-volt. So AH calculation is crucial before buying one.

More than that, to pinpoint the fish’s exact location, you can connect a fish finder with the trolling motor’s batteries. A continuous power supply is required to keep the trolling motor running for an extended period—That’s why choosing trolling motor batteries is essential. Make sure you keep reading to learn more about our picks for the best 12V and 24V lithium batteries for trolling motors.

What is a Lithium Trolling Motor Battery? 

Trolling motor batteries made of lithium iron phosphate are deep-cycle batteries that can be recharged many times (LiFePO4). It is designed to give trolling motors slow, constant power. The majority of lithium trolling motor batteries operate at 12 volts or 24-volt batteries.

What Battery Do I Need for a Trolling Motor?

12-volt wet cell, AGM, or lithium-ion batteries are commonly used in trolling motors. Usually, the voltages of batteries connected in series are added. A series of two 12-volt batteries provide 24 volts, while a series of three provides 36 volts. Parallel batteries’ capacity is put together in amp-hours (Ah).

Few users are concerned about how long will a 100Ah lithium battery will last on a trolling motor? For example, if two 100 Ah 12-volt batteries are linked, they provide 200 Ah at 12 volts and last 200 minutes. Trolling motors commonly run on 12, 24, or 36 volts.

In order to lengthen the run time of a 12-volt trolling motor, several 12-volt batteries can be linked in parallel. You can use one 24-volt battery or two 12-volt batteries in sequence for a 24-volt motor, and three 12-volt batteries power a 36-volt trolling motor in parallel.

Benefits of Lithium Trolling Motor Batteries

A lithium battery often lasts twice as long as a comparable lead-acid battery. Lithium batteries also last longer, are lighter and are more efficient. All of your questions about lithium batteries, such as, “Are lithium batteries excellent for trolling motors?” Will no longer be an issue after reading this article. Here are all the benefits of lithium batteries.

Exceptionally Light

Weight is a crucial component in smaller boats and vessels. Marine lead-acid batteries typically weigh between 60 and 70 pounds, and lithium batteries are far lighter than those found in marine applications, weighing around 30 pounds. For a 36-volt motor that requires three 12-volt batteries connected in series, a lithium battery solution might save you around 100 pounds.

Power and Charging Efficiency

Lithium batteries add to the system’s efficiency by reducing weight and increasing run-time. On average, battery efficiency is four times greater than run-time per pound. They also charge faster than lead-acid batteries (about two hours).

Integrated Battery Management System

Lithium-ion batteries have a built-in monitoring system and a built-in failsafe to prevent high or low-temperature damage and poor charging. This BMS system increases the battery lifespan.

More Strength

Trolling motors need a lot of cranking torque since their speeds fluctuate dramatically. Since they have such a small voltage drop when accelerating quickly, lithium batteries are better at supplying power than other batteries.

Longer Battery Life

Batteries made of lithium can last up to ten years, whereas those of wet-cell and AGM lead-acid are only good for two or four at most. Although lithium batteries are more expensive initially, they can save you money in the long term. 

Low Self-discharge Rate

Storage of AGM batteries at 68°F results in a monthly self-discharge rate of roughly 3 percent, whereas that of Gel-cell batteries is about 2 percent. On the other hand, good lithium batteries may self-discharge at a rate of 5-15% a year. 

12 Volt Lithium Trolling Battery

12 Volt Lithium Trolling Battery can hold a lot of power for a long time, but most of them are deep-discharge batteries, which means that they can hold 1A for a long time and 2A for a short time. The latter is ideal for 50 and 75Ah dual-purpose batteries with CCA values of 750 and 1000.

All batteries employ Lithium Iron Phosphate (LiFePO4) for protection. Regardless of the label, always measure the battery before buying. Here are a few standard 12 Volt Lithium batteries.

FAQs

1. How Many Batteries Do I Need for My Trolling Motor?

If your trolling motor requires 12 volts of power, one lithium battery will suffice. A total of two 24 volt batteries are likely to be required. You will likely need three of these batteries if your trolling motor is 36 volts.

2. Is a Lithium Trolling Motor Battery Worth It?

Battery prices for deep-cycle batteries are roughly one-third those of lithium batteries. In another way, the upfront cost savings don’t seem to be worth it because lithium batteries have a 50-100 times longer lifespan, double the run time, and lower battery weight by half.

3. How Long Will a Lithium Battery Run a Trolling Motor?

Batteries made of lithium marine batteries can last up to ten times longer and still provide 80 percent of their rated capacity over 2,000 kilometers.

4. How Long Will a 50ah Lithium Battery Last on a Trolling Motor?

A 32-foot boat with three 12volt 50AH lithium batteries can keep us bottom fishing for six hours and still have 30 percent of the batteries left.

Final Thought

Choosing the best lithium battery for a trolling motor is crucial because you don’t want to waste money on the wrong one. I hope this writing piece will help you choose your desired one.

Check your boat voltage and buy a compatible battery because reliable lithium trolling motor batteries help you fish from dawn till dusk without being concerned about the battery dying on your trolling motor.
