Best Battery For Minn Kota Trolling Motor

Navigating the Waters: Finding the Best Battery for Your Minn Kota Trolling Motor

As an avid fisherman, you've come to rely on your trusty Minn Kota trolling motor to provide a smooth, quiet, and efficient ride across the waters. But, like any piece of equipment, your trolling motor is only as powerful as its battery. That's why selecting the best battery for your Minn Kota trolling motor is crucial to making the most out of your fishing adventures. In this blog post, we'll guide you through the murky waters of trolling motor batteries and help you choose the perfect fit for your Minn Kota motor.

Choose the Right Type of Battery: AGM vs. Lithium-ion

Before we dive into specific battery models, let's talk about the two primary types of batteries suitable for trolling motors: Absorbent Glass Mat (AGM) and Lithium-ion.

AGM Batteries

AGM batteries are a popular choice, designed with a fiberglass mat soaked in electrolytes. The use of this mat provides:


  • Reliable and low-maintenance performance
  • Sealed, spill-proof construction
  • Ability to handle high currents
  • Good value for the cost

Lithium-ion Batteries

While AGM batteries have been the go-to option for years, Lithium-ion batteries have been gaining momentum. These batteries offer several benefits, such as:

  • Lightweight design
  • Faster charging times
  • Longer lifespan
  • Greater efficiency

However, the primary downside to Lithium-ion batteries is their hefty price tag. You'll need to weigh the benefits against the cost when deciding the type of battery to choose for your trolling motor.

Determine the Right Battery Size and Capacity

Now that you know the battery types available, it's time to consider the capacity. Depending on your Minn Kota trolling motor, you'll need a battery with enough amp hours (Ah) to power your motor for an extended period.

As a general rule, more powerful trolling motors require batteries with higher amp hours. It's essential to match the battery capacity to your motor's specifications. For instance, a 12-volt motor would require a 12-volt battery with a minimum of 50 Ah. However, higher Ah batteries are better suited for those long fishing trips.

What battery lasts the longest for a trolling motor?

Lithium Iron Phosphate batteries, also referred to as LiFePO4 batteries or lithium marine batteries, boast the longest battery lifespan of any marine or deep-cycle battery. They are the best battery for a trolling motor any boatsman, yachtsman, or angler could want.

How do LiFePO4 batteries compare to traditional lead-acid batteries?

LiFePO4 batteries offer several advantages compared to traditional lead-acid batteries. They are significantly lighter resulting in improved boat speed and fuel efficiency. Furthermore, they have a faster charging rate, a longer lifespan, and a higher discharge rate. While LiFePO4 batteries may have a higher upfront cost, their longevity and overall performance make them more cost-effective in the long run.

Can LiFePO4 batteries handle extreme temperatures?

Yes! LiFePO4 batteries are designed to withstand a wider range of temperatures than traditional lead-acid batteries. They perform well in both high and low temperatures, making them a reliable option for trolling motors regardless of the climate or weather conditions.

How do I charge and maintain my LiFePO4 battery?

Caring for your LiFePO4 battery is quite simple. It is recommended to use a lithium-specific charger to charge and maintain the battery. These chargers are designed to ensure that your battery stays balanced and at peak performance. Additionally, it is essential to avoid overcharging or completely discharging the battery since this can lead to reduced battery life. Some LiFePO4 batteries come with built-in battery management systems (BMS). This feature helps maintain the battery's health and prevents over-discharging and overcharging.

Can I use a lithium battery in my older trolling motor?

Yes, you can generally use lithium batteries with older trolling motors. However, it is important to check the manufacturer's recommendations for the specific battery voltage and capacity requirements before making the switch. Some motors may require adjustments or battery management systems to handle lithium batteries safely.

How long will a LiFePO4 battery last on a single charge?

The run time of a LiFePO4 battery depends on various factors, including the capacity of the battery, the speed of the trolling motor, and the weight of the boat. On average, a fully charged LiFePO4 battery should last anywhere from 6 to 12 hours of continuous use with a trolling motor, depending on the load and conditions.

In conclusion, LiFePO4 batteries are an excellent choice for trolling motors due to their long lifespan, minimal maintenance, and adaptability to a wide range of trolling motors and environments. While they may come at a higher initial cost, their overall performance and longevity make them a valuable investment for any serious boater or angler.

Additional Questions

What’s the optimal kind of battery to use with a Minn Kota trolling motor?

For a Minn Kota trolling motor, the ideal choice would be a **12-volt deep cycle marine battery** with a **110 amp-hour rating**, or in other words, **a group 27 size battery**. This should provide a reliable source of power for your trolling motor. The amp-hour rating is significant because the higher the amp-hour rating, the longer your motor will run without needing a recharge. This is vital particularly on long fishing trips where you need your trolling motor to perform for extended periods. Remember that batteries must be appropriately maintained and charged to maximise their lifespan and performance.

Which battery has the longest life for a trolling motor?

When you’re out fishing, you need a battery that can hold its charge for a good while – a battery with a long life span. And in that category, nothing beats a **Lithium Iron Phosphate battery**, also known as a **LiFePO4 battery**, or a **lithium marine battery**. This type has proven to outlast other types of marine or deep-cycle batteries. With these batteries, your trolling motor would have a significantly extended running time before requiring a recharge. That means more time for fishing and less time worrying about your battery running out!

What’s the ideal battery setup for my Minn Kota?

Your Minn Kota trolling motor would work best with any **lead-acid, deep cycle marine 12-volt battery/batteries**. However, for best results, make sure the **marine battery has a 110-ampere hour rating or more**, which is usually assigned to a **Group 27** battery or higher. This would give your Minn Kota the stamina and longevity it needs to provide the best performance for your fishing adventures. And remember, although this is a setup recommendation, consider your specific needs when you’re planning your battery configurations.

What size of battery should I get for my 50-pound thrust trolling motor?

Thrust is the amount of energy your trolling motor provides, and having a 50-pound thrust motor means you need an equally capable battery. Hence, for a 50-pound thrust trolling motor, most boaters would recommend a **12-volt deep cycle marine battery** with **a 110-amp hour rating**, or **a Group 27** battery. This accommodates your motor’s power requirements perfectly and should give you a solid run-time to enjoy your fishing trip.
