12V vs 24V Trolling Motor Lithium Battery Zone, March 26, 2025March 26, 2025 Choosing the right trolling motor is one of the most important decisions for any angler or boater. Whether you’re navigating calm lakes in a small kayak or tackling larger waters in a bigger boat, your motor plays a crucial role in your overall experience on the water. One of the key factors to consider is the voltage of your trolling motor—specifically, whether you should go with a 12V or 24V system. Both have their benefits, but understanding the differences between them can help you make a more informed decision based on your boat size, usage, and fishing needs. In this guide, we’ll break down the advantages, disadvantages, and key distinctions between 12V and 24V trolling motors, so you can choose the best one for your next adventure on the water. Understanding Voltage in Trolling Motors Voltage plays a crucial role in determining the performance and efficiency of trolling motors. Whether you’re a casual fisherman or a dedicated angler, understanding the difference between 12V and 24V trolling motors will help you make a more informed decision when selecting the right motor for your needs. What Does Voltage Mean for Trolling Motors? In simple terms, voltage refers to the electrical potential difference that powers the motor. A higher voltage means the motor can handle more electrical power, which translates into greater thrust and performance. Trolling motors typically operate on 12V or 24V systems, with each offering distinct advantages based on your specific boating needs. The Role of Voltage in Power Output The primary role of voltage in a trolling motor is to determine how much power the motor can produce. A 12V system, for instance, typically draws less power than a 24V system, meaning the 24V motor will usually be more powerful. This increased power output is essential for larger boats or longer trips, where more thrust is needed to maintain speed and control. For smaller, lighter boats or short fishing trips, a 12V motor may suffice. However, for larger boats or longer trips, a 24V motor offers better performance, as it can provide more thrust without overworking the battery. This difference in power also affects battery life, as a 12V motor will generally draw more current to produce the same level of thrust as a 24V motor. Power Efficiency and Battery Life One of the key differences between 12V and 24V trolling motors is the efficiency of power usage. A 24V trolling motor is typically more power-efficient, meaning it will use less current to produce the same amount of thrust compared to a 12V motor. This results in a longer battery life, especially on longer outings. For example, if you’re using a 12V motor, it might draw higher amounts of current to achieve the desired speed or thrust. In contrast, a 24V motor requires less current for the same performance, allowing you to go for longer periods without draining the battery. This can be a game-changer for anglers who spend extended periods on the water, as they can avoid having to recharge or swap batteries as frequently. Voltage and Motor Speed Voltage also impacts the speed and thrust capabilities of the trolling motor. With a 24V trolling motor, you generally get more speed and thrust compared to a 12V motor, making it ideal for larger boats or fast-moving waters. A 12V motor might be sufficient for slower, calm waters or small boats, but when you need more power to navigate through stronger currents or larger bodies of water, a 24V motor will perform much better. It’s important to note that many modern trolling motors come with variable speed settings. These settings allow the user to adjust the motor’s performance, but even at lower speeds, the motor’s overall power is still influenced by the voltage it operates on. A 24V motor will typically provide more consistent performance across different speed settings, making it a more versatile option. Weight and Space Considerations Another aspect influenced by voltage is the weight and space required for the trolling motor and its batteries. A 24V system generally requires two 12V batteries wired together, while a 12V system only requires a single battery. This adds to the weight and space needed for the 24V setup, which can be a consideration for boaters who have limited space or are looking to minimize weight. However, the trade-off in weight and space is often worth it for the extra power and efficiency that a 24V motor provides, especially if you have a larger boat or plan to spend more time on the water. A 12V motor, while lighter and more compact, may not provide the necessary power for extended trips or bigger boats. 12V Trolling Motor A 12V trolling motor is one of the most commonly used motors for smaller boats and short fishing trips. It operates on a single 12-volt battery, providing a good balance of power, efficiency, and affordability for many anglers.

For shorter excursions or in areas where you don’t need continuous power, a 12V trolling motor can perform adequately, offering a balance between power and battery usage. Lightweight: Since they only require one battery, 12V trolling motors are often lighter than their 24V counterparts. This can be a key benefit for boaters who are looking to minimize weight, particularly in smaller boats where every pound counts. Limitations of a 12V Trolling Motor Limited Power and Thrust: The main limitation of a 12V trolling motor is its relatively lower power output compared to a 24V motor. This makes it less suitable for larger boats or rougher water conditions. If you need to travel long distances, or if you have a larger boat, a 12V motor might struggle to maintain a consistent speed and performance. Battery Drain: While 12V motors can be sufficient for smaller boats and short trips, they tend to draw more power to achieve the same thrust as a 24V system. This can lead to faster battery depletion, meaning you may need to recharge or swap batteries more frequently during longer outings. For boaters who spend significant time on the water, this can be a drawback. Not Suitable for Heavy Load or Fast Waters: 12V trolling motors are best for light to moderate use. If you plan on carrying a heavy load or fishing in fast-moving waters, a 12V motor might not provide the thrust needed to keep your boat moving at an adequate pace. Limited Range and Performance: If you plan to use your trolling motor for long distances or in harsh conditions, a 12V motor may not be able to keep up with the demand. As the battery drains, the motor’s performance will decrease, affecting your ability to navigate effectively. When to Choose a 12V Trolling Motor? A 12V trolling motor is an excellent choice for boaters who have small, lightweight boats and typically fish in calm, sheltered waters. It is particularly useful for short fishing trips, where power consumption and battery life are not a major concern. If you’re an occasional angler who only uses your boat in small lakes or ponds, or if you simply need a low-maintenance, cost-effective solution, a 12V trolling motor will likely be sufficient for your needs.

This is particularly beneficial for those who spend extended periods on the water and don’t want to be constantly recharging or swapping out batteries. Better Performance on Larger Boats: Larger boats require more thrust to move efficiently, and a 24V motor is the ideal choice for vessels over a certain size. Whether you are fishing from a large bass boat or a pontoon, the added power of a 24V trolling motor helps maintain a consistent speed and gives you more control in rougher waters. For these larger vessels, a 12V motor might struggle to provide the necessary thrust, while a 24V motor is designed to handle the demands of bigger boats. Longer Range and Greater Speed: The increased power from a 24V motor allows for greater speed and longer distances. If you’re planning to travel a considerable distance or fish in areas that require more speed, a 24V motor offers the necessary capabilities. This can be especially important for those who need to cover large bodies of water quickly or who regularly fish in areas where speed is essential. Consistent Speed and Performance: As a 24V trolling motor uses more efficient power management, it can maintain a consistent speed for longer periods. Even when the battery starts to deplete, the motor’s performance won’t drop as quickly as a 12V motor, ensuring that your boat continues to move steadily without sudden slowdowns. Limitations of a 24V Trolling Motor Higher Initial Cost: One of the main drawbacks of a 24V trolling motor is the higher upfront cost. Since it requires two 12V batteries and is generally more powerful, it can be more expensive both in terms of the motor itself and the additional equipment needed to support it. This makes a 24V motor a larger investment compared to a 12V system, which may be a consideration for anglers on a budget. Increased Weight: The two 12V batteries required for a 24V motor can add significant weight to your boat. For boaters with limited space or those concerned about weight distribution, this added weight might be a downside. The motor and battery setup can make the boat heavier, which could affect performance in some cases, especially if your boat is already carrying a heavy load. Complex Setup and Maintenance: With two 12V batteries connected in series, the setup of a 24V trolling motor is more complex than a 12V system. You will need to ensure that the batteries are correctly wired and maintained, and that both batteries are charged properly. This can require additional knowledge and time to ensure everything is functioning properly, which might be intimidating for first-time boat owners. Space Requirements: The space required for a 24V system can be a limiting factor. With two batteries, a charger, and the motor itself, you’ll need more room in your boat to accommodate everything. This can be problematic for smaller boats where space is already at a premium, as adding a 24V system may reduce the available storage or seating. When to Choose a 24V Trolling Motor? A 24V trolling motor is ideal for boaters who have larger boats or frequently fish in more challenging conditions. If you’re using a boat that weighs more than 1,500 pounds or need to cover longer distances, a 24V motor will provide the necessary thrust and efficiency to get you where you need to go. Additionally, if you regularly fish in areas with strong currents, heavy winds, or turbulent waters, a 24V motor will ensure you have the power and control needed to stay on course. The 24V motor is also a great choice for anglers who want to maximize battery life. If you’re planning a full-day fishing trip or need to rely on your motor for longer periods, the extended battery life and power efficiency of a 24V system will allow you to keep going without worrying about battery depletion. Key Differences Between 12V and 24V Trolling Motors Choosing between a 12V and 24V trolling motor is a decision that significantly affects your boating experience, especially when it comes to performance, efficiency, and suitability for different types of boats and fishing trips. While both options have their advantages, understanding the key differences between them is crucial for making the right choice based on your specific needs. Power and Thrust One of the most significant differences between 12V and 24V trolling motors is the amount of power and thrust they provide. A 12V trolling motor is typically designed to provide adequate power for smaller boats, such as kayaks, canoes, or small aluminum boats. These motors are ideal for calm waters and short trips, where only a moderate level of thrust is required. However, when the boat is larger or requires more thrust, a 12V motor may struggle to provide sufficient power. In contrast, a 24V trolling motor is designed for larger boats and more demanding conditions. By using two 12V batteries in series, a 24V motor can generate significantly more power, which translates to greater thrust and better performance on larger boats, in rougher water, or under heavier loads. If you’re dealing with fast-moving currents, windy conditions, or a heavier boat, the 24V motor will provide the necessary thrust to maintain speed and control. Battery Life and Efficiency Battery life is another crucial area where the two types of motors differ. A 12V trolling motor typically draws more current to achieve the desired thrust, meaning that the battery will drain more quickly, especially on longer trips. For anglers who fish for several hours or need to cover large distances, a 12V motor may require frequent recharging or swapping out batteries. On the other hand, a 24V trolling motor is more energy-efficient. The additional voltage allows the motor to produce more power without drawing as much current, leading to a longer battery life. This makes a 24V motor better suited for long-duration fishing trips, as you can travel farther without worrying about running out of battery power. The improved efficiency means that, even with a larger battery draw, you won’t experience a rapid loss of performance as the battery drains. Speed and Control When it comes to speed and control, 24V trolling motors typically outperform 12V motors. The added power from the 24V system allows the motor to maintain a higher speed, even when dealing with larger boats or challenging water conditions. If you need to navigate through fast-moving water or deal with heavy winds, a 24V motor will allow you to maintain more consistent control and speed. A 12V motor is generally sufficient for smaller, slower-moving boats or calmer water conditions. While a 12V motor can provide adequate speed in certain scenarios, it may struggle to maintain the same level of performance in more demanding conditions. In general, if you prioritize speed or require more control on the water, a 24V motor is the better option. Weight and Space Considerations Weight and space are important factors to consider, especially for boaters with limited room or a focus on portability. A 12V trolling motor requires only a single 12V battery, which reduces its overall weight and the space needed for installation. This makes it a great choice for smaller boats, kayaks, and canoes where space is limited and every pound matters. In contrast, a 24V trolling motor requires two 12V batteries, which adds both weight and space requirements. The added weight from the two batteries can be a concern for boaters who need to keep their boat as light as possible. However, the extra weight is generally worth it for the increased power and performance that a 24V motor offers. If your boat has the space and weight capacity to accommodate the additional batteries, the performance benefits may outweigh the downside of added bulk. Cost and Maintenance Cost is another important factor when comparing 12V and 24V trolling motors. A 12V motor is typically more affordable than a 24V system, making it a great choice for those on a budget or for anglers with smaller boats who don’t require high-power motors. The lower initial investment makes a 12V motor accessible to a wider range of boaters. In contrast, a 24V trolling motor is more expensive, both in terms of the motor itself and the additional batteries and accessories needed to support it. The cost of the batteries and their maintenance can add up over time, as you will need to replace the batteries every few years, depending on usage. Additionally, the more complex setup and wiring required for a 24V motor may involve more maintenance, especially if issues arise with the battery connections or the motor itself. Suitability for Different Boats A key consideration when choosing between a 12V and 24V trolling motor is the size and type of boat you’re using. A 12V motor is best suited for smaller boats that don’t require a lot of thrust, such as kayaks, canoes, or small dinghies. These types of boats typically weigh less and are easier to maneuver with a lower-powered motor. For larger boats, such as bass boats, pontoon boats, or boats that carry heavy loads, a 24V trolling motor is the better choice. The increased thrust and power provided by a 24V motor make it easier to maintain speed, especially when dealing with larger hulls or when you need to travel longer distances.
