The runtime of a 50Ah battery on a trolling motor depends on several factors, including the power draw of the motor and any additional electrical demands. Generally, if a trolling motor draws around 10 amps, a 50Ah battery can last approximately 5 hours under ideal conditions. However, if the motor draws more power or if other devices are being used, this time will decrease.
Calculating Runtime for a 50Ah Battery
To estimate how long a 50Ah battery will last, you can use the following formula:
Example Calculation
- Power Draw of Trolling Motor: Suppose your trolling motor draws 10 amps.
- Battery Capacity: The battery capacity is 50Ah.
Using the formula:
This means that under these conditions, the battery would last approximately 5 hours.
Adjusting for Additional Loads
If you have other devices connected, such as lights or fish finders, you need to add their power draw to the trolling motor’s draw. For example:
- Trolling motor: 10 amps
- Lights: 2 amps
- Fish finder: 1 amp
Total Power Draw:
Now recalculate the runtime:
This means the battery would last about 3 hours and 51 minutes under these conditions.
Factors Affecting Battery Life
- Depth of Discharge: Regularly discharging a battery below its recommended level can shorten its lifespan. For lead-acid batteries, it’s advisable to avoid discharging below 50%, while lithium batteries can be discharged more deeply without damage.
- Temperature: Extreme temperatures can affect battery performance. Batteries perform best in moderate temperatures.
- Battery Age and Condition: Older batteries may not hold their charge as well as new ones, affecting runtime.
- Efficiency of the Trolling Motor: Different motors have varying efficiencies, which can impact how much power they draw during operation.
