3 Best Kayak Trolling Motor Batteries | Kayaks Hub

Explore the best kayak trolling motor batteries with our guide. Explore top options, size considerations, and expert tips for an optimized outdoor experience.


Kayaking and fishing are some of the most relaxing and rewarding outdoor activities. Whether you are exploring tranquil lakes or patiently waiting for your next big catch, having the right gear can make all the difference. In this blog post, we will guide you through the essential features to consider when selecting the best kayak trolling motor batteries.

What Size Battery for Kayak Trolling Motor?

Understanding the size of the battery required for your kayak trolling motor is crucial for maximizing both your time on the water and the performance of your kayak. Typically, the size of the battery is determined by the trolling motor’s power consumption, which is measured in amperes (amps) per hour. A common rule of thumb is to opt for a battery that can offer a continuous supply of power for your trolling motor for at least 4 to 6 hours.

For instance, if your motor consumes 20 amps per hour, a battery with a minimum capacity of 80 to 120 amp-hours (Ah) would be recommended to ensure a fulfilling kayaking or fishing experience without running short on power. Balancing weight with capacity is vital, as a heavier battery might offer more energy but can also make your kayak harder to maneuver.

How Long Will a Trolling Motor Battery Last on a Kayak?

The duration for which a trolling motor battery lasts on a kayak depends on various factors including its capacity (measured in ampere-hours), the speed at which the motor is operated, the weight of the kayak including load, and the condition of the water. Typically, a battery with a capacity of 100 ampere-hours can power a motor at low speed for about 10 to 12 hours. However, at higher speeds, the same battery may last only 3 to 4 hours. It’s important to consider your specific needs and usage patterns when selecting a battery for your kayak’s trolling motor to ensure a balance between performance and duration.

What Battery Should I Use for My Kayak Trolling Motor?

When selecting a battery for your kayak trolling motor, the best option typically falls between deep cycle marine batteries and lithium-ion batteries. Deep cycle marine batteries are designed for prolonged discharge at a steady rate and are a reliable and cost-effective choice for kayak trolling motors. They come in various sizes, allowing you to choose one that fits your space and weight requirements.

On the other hand, lithium-ion batteries, although more expensive, offer significant advantages such as lighter weight, longer lifespan, and faster recharging times. They also maintain a consistent output level throughout their discharge cycle. Ultimately, the choice depends on your specific needs, priorities, and budget. If you prioritize longevity and lightweight for ease of maneuverability, lithium-ion might be the ideal choice. However, for those who are more budget-conscious, a well-maintained deep cycle marine battery can serve effectively.

Key Considerations for Kayak Battery Selection

When it comes to selecting the right battery for your kayak’s trolling motor, there are several considerations that should guide your decision beyond just the type and size. These considerations ensure that you not only get value for your money but also a battery that fits seamlessly with your kayaking and fishing adventures. Below are some key factors to contemplate:

  • Compatibility: Ensure the battery you choose is compatible with your trolling motor. This includes checking the voltage requirements and the type of connections needed. Incompatibility can lead to poor performance or even damage to your motor.
  • Weight and Size: Given the limited space and the importance of maintaining your kayak’s stability and maneuverability, the weight and size of the battery are crucial considerations. Lighter and more compact batteries, such as lithium-ion options, are generally preferable for smaller kayaks.
  • Charging Time: Consider how long it takes for the battery to charge fully. If you plan to use your kayak frequently, a battery with a shorter charging time could be more convenient, ensuring you’re always ready to hit the water when you want to.
  • Durability and Maintenance: Look for batteries that are known for their durability and low maintenance, especially if you’ll be kayaking in saltwater or under harsh environmental conditions. This factor can greatly influence the overall lifespan and performance of your battery.
  • Cost-Efficiency: While initial costs are an important consideration, also think about the long-term value. A more expensive battery might offer greater efficiency and longevity, potentially saving money on replacements and maintenance in the long run.
  • Environmental Impact: If sustainability is important to you, consider the environmental impact of the battery. Lithium-ion batteries, for example, have a much lower environmental footprint over their lifecycle compared to lead-acid batteries.

Selecting the right battery involves balancing these considerations according to your specific needs and preferences. Whether you prioritize endurance, cost, environmental impact, or size and weight, there’s a suitable option out there for every kayaker and fisher. Making an informed choice ensures enjoyable and worry-free experiences on the water, letting you focus on the beauty of nature and the thrill of the catch.

Trolling motor battery setup

How long will a 100Ah battery last on a trolling motor?

The duration a 100Ah (ampere-hour) battery will last when powering a trolling motor is dependent on several factors, including the motor’s consumption rate in amps and how actively the motor is used. Typically, a trolling motor might consume anywhere from 20 to 40 amps per hour when run at full speed. With a 100Ah battery, under optimal conditions and assuming a nominal consumption rate of 25 amps per hour, you could expect around 4 hours of continuous use at maximum power.

However, it’s crucial to remember that the actual runtime can vary significantly based on the motor’s settings and usage patterns. For more prolonged periods out on the water, using the motor at lower speeds can extend battery life, offering more time for fishing or exploring without needing a recharge.

Is a 50Ah battery enough for a trolling motor?

Determining whether a 50Ah (ampere-hour) battery is sufficient for a kayak’s trolling motor hinges on various factors, such as the specific energy consumption of the motor and the intended duration of use. A 50Ah battery generally offers you less onboard energy storage compared to the 100Ah models discussed previously, which means it provides a shorter runtime. For lightweight kayaks and moderate use, where the motor is primarily utilized for gentle cruising or maintaining position rather than full-speed travel, a 50Ah battery might suffice.

It’s essential to calculate the motor’s amp draw and compare it against the battery’s capacity for a more accurate estimate. For casual or short-duration trips, a 50Ah battery could be a practical and cost-effective choice, though users seeking longer periods on the water without recharge might find it limiting.
