Trolling motor battery run time. If your battery is rated at 200 amperage hours and the draw of the motor is 25 amps you may have 8 hours of consistent useYou simply divide the total amperage hours by the draw of the motor. Its a good idea to use the maximum draw used for higher speeds. 100 amp hour rated battery 20 amp draw 5 hour run time.
Most manufacturers will only list a motors maximum amperage draw at top speed so you may need to estimate other amperage draws at various speeds using the max speed amperage draw as a baseline. 46lbs of thrust roughly draws 40 amps. However this is only true for 12V powered trolling motors.
Using a motor on lower speeds will increase battery life. A better estimate of this runtime can be achieved by dividing the max amp draw in half and using that answer in the equation. How to Calculate Your Battery Run Time.
This is calculated by dividing the Ampere hour rating of your battery by the average draw of the trolling motor. The ampere-hour rating of a battery is how much power it can dispense over time. For example you buy a 35Ah power battery and the average draw power of your trolling motor is 7 Amp.
Trolling motor battery run time. By hewesfisher Sat May 15 2010 1245 am. A 12v trolling motor will consume 11 - 12 amps per pound of thrust so a 55lb thrust trolling motor at full power will consume between 605 amps to 66 amps.
Most deep cycle batteries are rated in amp hours or with reserve capacity. For example one pro staff tested a 24v 54ah battery package for their 24v 80 lb thrust trolling motor during tournament fishing conditions lake fishing low wind and got a 14 hour run time. For an example of amp draw per power setting check out below for specifications for the Garmin Force Trolling Motor amp draw.
For trolling motors youll want to get a deep cycle battery. The higher the amp hours or Reserve Capacity the longer it will run your trolling motor. Your battery will wear out over time.
Age poor maintenance and over discharge will contribute to it no longer being able to deliver the rated amp hours. The ampere-hour rating of a battery is how much power it can dispense over time. For example you buy a 35Ah power battery and the average draw power of your trolling motor is 7 Amp.

If your batteries are having issues it can cut your fishing day short so here are a few tips for testing your batteries.

However this is only a theoretical number because depending on the type of battery you use you will never want to deplete it to 0 of capacity.
So if a motor is running at low speed and pulling 4 amps the battery should last around 25 hours. 100 amp hour rating 4 amps 25 hours. Similarly if the motor was running at top speed and pulling 40 amps the battery would last for 25 hours 100 amp hour rating 40 amps 25 hours.
If your battery has 100Ah capacity and your motor draws 20 amps of current you can calculate its run time by dividing 10020 5 hours. Your motors current draw depends on the speed you set it to and how heavy your boat is. If you use your trolling motor at lower speeds you will have a significantly lower current draw and much longer run time.

Based on how much and how long the trolling motor battery will be used will determine how big and how many batteries are needed. It is not uncommon to have three trolling motor batteries on a boat that frequently uses the trolling motor.
