A reliable trolling motor is indispensable for any serious angler. But a powerful motor is only as good as the battery that powers it. Choosing the right battery can significantly impact your fishing experience, determining how long you can stay on the water and how efficiently your motor performs. This article breaks down the best battery options for 12V, 24V, and 36V trolling motors, helping you make an informed decision and maximize your time on the water Trolling Motor Battery.
Understanding Your Trolling Motor Voltage
Before diving into battery specifics, it’s crucial to understand your trolling motor’s voltage. This dictates the number and type of batteries required.
- 12V Motors: Ideal for smaller boats and kayaks, 12V motors are the most common and require a single 12V battery.
- 24V Motors: Offering increased power and thrust, 24V motors are suitable for medium-sized boats and require two 12V batteries wired in series.
- 36V Motors: Designed for larger boats and demanding conditions, 36V motors provide the highest thrust and require three 12V batteries wired in series.
Battery Types: Which Reigns Supreme?
Several battery types are available, but for trolling motors, deep-cycle batteries are the gold standard. These batteries are designed for sustained discharge and recharge cycles, unlike starting batteries that provide a burst of power for engine ignition.
Here’s a breakdown of the most common deep-cycle battery types:
- Flooded Lead-Acid (FLA): The most affordable option, FLAs require regular maintenance, including checking and refilling electrolyte levels. They offer decent performance but are prone to spills and require proper ventilation.
- Absorbed Glass Mat (AGM): A sealed lead-acid battery, AGMs are maintenance-free and spill-proof. They offer better performance and longer lifespan than FLAs but come at a higher price.
- Lithium-Ion (LiFePO4): The premium option, lithium-ion batteries offer exceptional performance, lightweight design, and long lifespan. They are significantly more expensive than lead-acid batteries but provide superior energy density and faster charging.
Choosing the Right Battery for Your Voltage
Now, let’s explore the best battery options for each trolling motor voltage:
12V Trolling Motor:
- For a 12V system, a high-quality deep-cycle AGM or lithium-ion battery is recommended.
- AGM: Offers a good balance of performance and cost. Look for a battery with a high amp-hour (Ah) rating to ensure longer run times. A 100Ah or greater battery is often recommended.
- Lithium-ion (LiFePO4): If budget allows, a lithium-ion battery is the best choice. They are lighter, offer faster charging, and provide more consistent power throughout the discharge cycle.
- Consider the weight of the battery, especially for kayaks and smaller boats.
24V Trolling Motor:
- For a 24V system, you’ll need two 12V batteries wired in series.
- AGM: Using two identical AGM batteries ensures balanced performance and lifespan. Again, a 100Ah or greater rating is preferred for each battery.
- Lithium-ion (LiFePO4): Two identical 12V lithium-ion batteries will deliver exceptional performance and extended run times. Ensure both batteries have a built-in Battery Management System (BMS) for safety and longevity.
- Consistent battery quality is paramount, mixing different battery types or age is not recommended.
36V Trolling Motor:
- For a 36V system, you’ll require three 12V batteries wired in series.
- AGM: Three identical high-capacity AGM batteries are a reliable choice. Ensure proper wiring and battery maintenance.
- Lithium-ion (LiFePO4): Three identical lithium-ion batteries provide the ultimate power and performance. The weight reduction is also significant, especially in larger boats.
- A high quality 36v compatible charger is required for proper charging of this setup.
Key Considerations:
- Amp-Hours (Ah): A higher Ah rating translates to longer run times.
- Weight: Consider the battery’s weight, especially for smaller boats.
- Size: Ensure the battery fits within your boat’s battery compartment.
- Maintenance: AGM and lithium-ion batteries are maintenance-free, while FLAs require regular maintenance.
- Budget: Lithium-ion batteries are the most expensive, followed by AGMs, and then FLAs.
- Charger: Use a charger specifically designed for deep-cycle batteries. For lithium batteries it is very important to use a charger designed for lithium iron phosphate batteries.
Conclusion:
Choosing the best battery for your trolling motor is a crucial decision that impacts your fishing experience. Whether you opt for a reliable AGM or invest in the superior performance of lithium-ion, consider your motor’s voltage, boat size, and budget. By making an informed choice, you’ll ensure your trolling motor delivers the power and reliability you need for a successful day on the water.
