Best Trolling Motor Battery: Types & Top Picks

The last thing you want on a fishing trip is for your trolling motor to lose power. Your battery is key to keeping you moving, whether you're in a quiet bay or facing strong currents. But with so many options on the market, choosing the right trolling motor battery can be overwhelming.

In this guide, we'll break down the different types of trolling motor batteries, highlight top picks for each, and help you select the best one for your needs—ensuring you don't need to worry about power and focus on the joyful time on the water.

Types of Trolling Motor Battery

There are three main types of batteries commonly used for trolling motors: Flooded Lead-Acid, AGM, and LiFePO4.

Flooded Lead Acid Battery

The most affordable option and has been the traditional choice for many boaters. Flooded lead-acid batteries require regular maintenance, such as topping off water levels, and are less efficient in cold weather. They also tend to be heavier and bulkier, limiting their overall performance.

AGM (Absorbent Glass Mat) Battery

AGM batteries are a step up from flooded lead acid in terms of performance and maintenance. These are sealed, spill-proof, and more efficient in cold conditions. AGM batteries generally last longer than flooded lead-acid types and are more resistant to vibration.

LiFePO4 (Lithium Iron Phosphate) Battery

LiFePO4 batteries are the latest and most advanced technology for trolling motor batteries. They are much lighter, offer a longer lifespan, and charge faster than their lead-acid counterparts. Although more expensive upfront, their superior performance, LiFePO4 batteries still gain popularity from large ranges of anglers.

What is the Best Type of Battery for an Electric Trolling Motor?

The best type electric trolling motor batteries is absolutely LiFePO4 batteries. They last the longest and are the most lightweight with the least maintenance in deep cycle use. Despite a higher initial cost, the long-term benefits make LiFePO4 batteries an investment worth considering.

Considerations when Buying Trolling Motor Batteries

When choosing a trolling motor battery, there are a few key factors to consider for optimal performance:

Capacity and Power Output

Choose a battery with enough capacity to meet your runtime needs. For example, a 100Ah battery can run a 55lb trolling motor for around 2 hours at full speed. Ensure the battery’s capacity matches your motor’s power requirements.

Size and Weight

Select a compact, lightweight battery that fits your boat’s space, especially if you have a small boat like a kayak or a skiff. A lighter battery will improve performance and efficiency. Always choose the right battery size for your trolling motor.

Voltage

Match the battery voltage to your motor's requirements (12V, 24V, or 36V system). Using the correct voltage ensures optimal performance and prevents damage.

12V batteries are best for most trolling motors up to 70 lbs of thrust, while 24V batteries suit motors with 70-100 lbs of thrust, and 36V batteries are ideal for larger motors over 100 lbs.

Battery Type

LiFePO4 lithium batteries are ideal for trolling motors due to their longer lifespan, faster charging, and reduced weight compared to lead-acid batteries.

Durability and Protection

Ensure the battery has a reliable BMS to protect against overcharging, over-discharge, over-current, overheating, and short circuits. For marine environments, look for batteries that are resistant to water, salt, and corrosion.
