Choosing the best trolling motor battery ensures longer run times, smoother rides, and a more reliable experience on the water. At Redline Battery Supply, we’re here to help you navigate the sea of options and select the perfect battery for your needs. If you love fishing or boating in the serene waters around Melbourne, Florida, your trolling motor is your silent partner for success.
Why Your Trolling Motor Battery Matters
Your trolling motor is different from your outboard motor—it’s designed for quiet, steady propulsion, especially useful when fishing in shallow or calm waters. The trolling motor battery powers this device and needs to be optimized for deep cycling—providing consistent energy over a long period rather than a quick burst like a starting battery.
A poor-quality or mismatched battery can leave you stranded—or worse, compromise your day on the water.
Types of Trolling Motor Batteries
There are three primary types of batteries to consider:
1. Lead-Acid Wet Cell Batteries
Pros: Affordable, widely available.
Cons: Needs routine upkeep (such as monitoring water levels) and is susceptible to damage from vibrations.
Best for: Occasional boaters on a budget.
2. AGM (Absorbent Glass Mat) Batteries
Pros: No maintenance required, sealed against spills, built to withstand vibrations, and lasts longer than traditional wet cell batteries.
Cons: More expensive upfront.
Best for: Regular or semi-regular boaters who want reliability without maintenance hassle.
3. Lithium-Ion Batteries
Pros: Lightweight, fast charging, extremely long life cycles, consistent power delivery.
Cons: Highest cost upfront.
Best for: Serious anglers or boaters who demand top performance and efficiency.
Key Factors to Consider
Battery Capacity (Amp-Hours)
Measured in amp-hours (Ah), this tells you how long your trolling motor battery will last on a full charge. A battery with a higher amp-hour rating will keep your motor running for a longer period.
Voltage
Trolling motors typically operate on electrical systems rated at 12, 24, or 36 volts. Make sure your battery or battery bank matches the motor’s requirements.
Durability
Look for batteries designed for marine use. In the rough waters around Florida’s coastlines and inlets, you need something vibration-resistant and sealed.
Charging Time
If you’re frequently on the water, opt for a battery that recharges quickly or consider investing in a smart marine charger.
What Size Trolling Motor Battery Do You Need?
Here’s a rough guideline based on motor thrust:
30–55 lbs thrust: 12V battery
60–80 lbs thrust: 24V system (2x 12V batteries)
100+ lbs thrust: 36V system (3x 12V batteries)
