What Size Battery Do I Need for a Trolling Motor?
Choosing the correct battery size for a trolling motor depends on motor voltage, amp-hour capacity, and desired runtime. Using the right battery ensures consistent power, optimal efficiency, and longer battery life, allowing safe and enjoyable boating experiences without unexpected power loss.
How Do You Determine Trolling Motor Voltage?
Trolling motors typically operate at 12V, 24V, or 36V. Check the motor specifications to select a compatible battery. Using the correct voltage prevents damage and ensures the motor delivers its rated performance.

What Amp-Hour (Ah) Rating Is Required?
Amp-hours indicate how long a battery can supply a certain current. For example, a 12V 100Ah battery can theoretically deliver 10 amps for 10 hours. Higher Ah ratings allow longer operation without recharging.
Battery Voltage vs Amp-Hour Example
| Motor Voltage | Battery Ah | Approximate Runtime (Hours) |
|---|---|---|
| 12V | 100 Ah | 10 |
| 24V | 100 Ah | 5 |
| 36V | 100 Ah | 3.3 |
How Does Motor Power Affect Battery Size?
Motor power, measured in amps or watts, determines the required battery capacity. Higher-powered motors consume more energy, necessitating larger batteries to maintain runtime.
Why Is Runtime Important in Battery Selection?
Runtime determines how long you can use the trolling motor before recharging. Calculating runtime ensures you have sufficient energy for fishing trips, navigation, and emergencies.
