The runtime of a 24-volt lithium battery on a trolling motor depends on several factors, including the battery’s capacity (amp-hours), the power draw of the trolling motor, and any additional electrical demands from other devices. Generally, a well-maintained 24V lithium battery can provide significant run time, often lasting anywhere from 3 to 8 hours or more, depending on usage conditions.
Key Factors Influencing Runtime
- Battery Capacity:
- The capacity of the battery is measured in amp-hours (Ah). A higher capacity means longer run times. For example, a 100Ah battery can theoretically run longer than a 50Ah battery at the same power draw.
- Power Draw of the Trolling Motor:
- The power draw, measured in amps, varies based on the motor’s speed setting and load conditions (e.g., wind and current). Typical trolling motors may draw anywhere from 20 to 40 amps at full throttle.
- Additional Electrical Loads:
- If you are using other devices (like lights or fish finders), their power consumption will affect the overall runtime. For instance, if your trolling motor draws 20 amps and your other devices draw an additional 5 amps, your total draw would be 25 amps.
Calculating Runtime
To estimate how long a 24V lithium battery will last on a trolling motor, you can use the following formula:Runtime hours =Battery Capacity Ah Total Current Draw A Runtime hours =Total Current Draw A Battery Capacity Ah
Example Calculation:
- Suppose you have a 100Ah lithium battery, and your trolling motor draws 25 amps (20 amps for the motor + 5 amps for other devices):
Runtime=100Ah25A=4 hoursRuntime=25A100Ah=4 hoursThis means under these conditions, you could expect approximately 4 hours of runtime before needing to recharge.
Typical Scenarios
- Low Power Setting: If using a lower power setting (e.g., 10-15 amps), you could potentially extend the runtime to 6-10 hours, depending on the battery capacity.
- High Power Setting: At higher settings (e.g., 30-40 amps), expect runtimes closer to 2-3 hours for a 100Ah battery.
Latest News
