How to Choose the Best Battery For Trolling Motor

Choosing the right battery for your trolling motor involves evaluating several key factors. Here's a guide to help you make the best choice:

Voltage Compatibility

Understanding voltage compatibility is essential when choosing a LiFePO4 trolling motor battery. Trolling motors typically come in 12V, 24V and 36V versions, depending on the size and weight of your boat. To ensure optimal performance and avoid damaging your motor, select a trolling motor deep cycle battery that matches your motor's voltage requirements.If you need to use multiple batteries, they can be connected in parallel (linking positive terminals together and negative terminals together). This setup increases run time without raising the voltage, providing a safer and more efficient energy output for your trolling motor.

Weight and Space Considerations

The weight and space on your boat are critical when selecting a kayak trolling motor battery. A lighter kayak battery is easier to handle and can improve your boat's acceleration and speed. Compact batteries are ideal, as they maximize usable space on your boat without compromising power.Choosing a deep cycle trolling motor battery that's both powerful and compact enhances your boating experience. Avoid large, cumbersome batteries that might overcrowd your boat and reduce its performance. By carefully considering weight and size, you can ensure you select the best lithium trolling motor battery for your needs.

Battery Life and Cost Efficiency

When choosing a trolling motor battery, it's important to consider longevity and cost efficiency. Lithium trolling motor batteries can last up to 10 years, far outlasting traditional lead-acid or AGM batteries, which typically need replacing every 2-4 years. Although lithium trolling motor batteries have a higher upfront cost, their long lifespan can save you money over time. By reducing the frequency of battery replacements, you get a more reliable and cost-effective solution for powering your trolling motor.

How Many Amp Hours Should the Trolling Motor Battery Have?

Choosing the right amp-hour rating for your trolling motor deep cycle battery is crucial to ensure you have enough power for your needs. The amp-hour (Ah) rating indicates how much current your trolling motor battery can provide in an hour, making it an essential factor in determining how long you can stay out on the water.

For example, if your motor draws 5 amps at a low speed, a 100 Ah battery would give you approximately 20 hours of runtime (100 Ah / 5 amps = 20 hours). On the other hand, if your motor draws 20 amps at high speed, the same battery would last around 5 hours (100 Ah / 20 amps = 5 hours). Understanding this calculation helps you better manage your time on the water.

A good rule of thumb is to choose a deep cycle trolling motor battery with an amp-hour rating that is at least twice the maximum amp draw of your motor. For instance, if your trolling motor draws 50 amps at full power, a 100 Ah lithium trolling motor battery would provide about two hours of runtime. However, since you likely won’t run your motor at full power continuously, you can expect longer runtimes at lower speeds. For more information on understanding battery Amp hours choose, please see our guide on Trolling Motor shopping guide.

For trolling motor use, we recommend a battery with at least a 100 amp-hour rating, a Group 24 size, and 175 minutes of Reserve Capacity (RC). The WattCycle 12V 100Ah LiFePO4 Battery with Bluetooth for Trolling Motors features a 120A BMS and is specifically designed for trolling motors.

In summary, understanding your motor’s power requirements and matching them with the appropriate amp-hour rating on your trolling motor deep cycle battery is key to enjoying a longer, more reliable experience on the water.

Customer Experiences about WattCycle Trolling Motor Battery

Winter fishing can be tough, especially up here where it gets seriously cold. I was initially concerned about how a lithium trolling motor battery would perform in freezing conditions, but the WattCycle battery exceeded my expectations. Even on the coldest mornings, the battery powers up without a hitch. I’m particularly impressed with the low-temperature cut-off feature, which gives me peace of mind that the battery won’t get damaged. The battery holds its charge incredibly well, and even after a long day out on the water, I still have power left. It’s also easy to monitor the charge level with the Bluetooth app—no more guessing how much juice I have left. It’s been a solid upgrade from the old lead-acid batteries.
