Buying Guide – How to Choose the Best Battery to Run a Trolling Motor

Selecting the right battery depends on your boat size and how long you stay out. This guide covers the key factors to consider.

Battery Chemistry

Lithium iron phosphate batteries are lighter and last longer than AGM but cost more. AGM is cheaper but heavier and has a shorter lifespan.

Choose lithium if you want weight savings and longevity. Choose AGM for budget and simplicity.

Capacity and Amp Hours

Higher amp hours mean longer run time for your motor. Calculate your motor's amp draw to estimate needed capacity.

Look for at least 100Ah for short trips. Consider 200Ah or more for all day fishing.

Weight and Space

Lithium batteries are much lighter than AGM which helps with boat balance. Ensure the dimensions fit your battery box.

Check the physical size and weight to ensure your boat can handle it safely.

Cycle Life

Cycle life indicates how many times you can recharge the battery. Lithium offers thousands of cycles while AGM offers hundreds.

A higher cycle life means the battery will last for many years of use.

Charging Requirements

Lithium needs a specific charger to be safe. AGM can use standard marine chargers. Check if your current charger is compatible.

If you switch to lithium you must buy a lithium compatible charger to avoid damage.

Temperature Protection

Cold weather can hurt lithium batteries. Look for built in low temperature protection features for safety.

Ensure the battery has cut off features for freezing conditions to prevent damage.

Warranty and Support

Check the manufacturer warranty length. Good support helps if you face issues with the battery.

A long warranty indicates the brand trusts the quality of their product.

Total Cost of Ownership

Lithium costs more upfront but may save money over time due to longer life. AGM costs less now but may need replacement sooner.

Think about how long you plan to use the boat before deciding on a budget.

How to Use and Care for Your Battery to Run a Trolling Motor

Always charge your battery with the correct charger for the battery type. Using the wrong charger can damage lithium batteries or cause safety issues.

Store your battery in a cool dry place when not in use. Extreme heat or cold can reduce battery life and performance over time.

Regularly check your terminals for corrosion and clean them if needed. A clean connection ensures efficient power delivery to your trolling motor.
