Frequently Asked Questions

What type of battery is best for a 24 volt trolling motor?

Lithium LiFePO4 batteries offer the best performance and longest lifespan, but they cost more. AGM batteries are a reliable mid-range option with good cycle life and no maintenance. Flooded lead-acid is the cheapest but requires regular maintenance and has shorter life. The best choice depends on your budget and how often you fish.

How many amp hours do I need for a 24 volt trolling motor?

For a typical day of fishing, 80-100Ah total (using two 12V batteries in series) is a common recommendation. If you fish all day at high speeds, consider 120Ah or more. Lithium batteries provide more usable capacity than AGM of the same Ah rating due to deeper discharge capability.

Can I use two 12V batteries in series for a 24V system?

Yes, that is the standard method. Connect the positive of one battery to the negative of the other to create 24V. Ensure both batteries are identical in type, age, and capacity for optimal performance and longevity.

Do I need a special charger for AGM or lithium batteries?

AGM batteries require a charger with an AGM profile to prevent overcharging. Lithium batteries need a charger specifically designed for LiFePO4 chemistry; using a lead-acid charger can damage them. Always match the charger to the battery type.

How long will a 24 volt trolling motor battery last on a single charge?

Runtime depends on battery capacity, motor thrust, speed setting, and boat size. As a rough estimate, a 100Ah AGM system at medium speed may last 4-6 hours. Lithium can often deliver 20-30% more runtime due to higher usable capacity. Always check manufacturer guidelines for your motor.
