Its a good idea to use the maximum draw used for higher speeds.

Electric trolling motor amp draw. 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. 16062020 To estimate the run time of a trolling motor you do the following equation. POER Electric Trolling Motor amp draw figures represent actual on-the-water conditions at different speed level settings with all of the motor.

A 100 amp-hour trolling motor battery would last about 150 minutes of trolling. 25032009 That said the general rule of thumb for a 12V trolling motor without choppermaximieretc is roughtly 09-1A draw for every thrust produced. That equates to a max of 50 amps or so for your motor.

04022021 An average 55-pound thrust trolling motor draws a max current of around 40 amps. Check out our full line of transom mounted saltwater trolling motors. A trolling motors exact amp draw can be required from POER.

Using the formula youll get 33 hours. So lets assume you want to only use 85 leaving 15 left. We can estimate amp draw based off the pounds of thrust a trolling motor is rated for by rounding down to the nearest ten.

Here is a graph to about trolling motor battery run time. Most manufacturers state amperage draw in max amps to get the average you divide the rating by 2. In this way you have around 15 remaining hours as per the following calculation.

A starter of even a small motor starting device is able to give away about 100 amp. When calculating trolling motor run time there are two things you need to know. Disconnect the motor leads at the battery.

Using the complete battery is detrimental to its health so you can try to use 50 of it. However this is only true for 12V powered trolling motors. Set the motor at the full power setting.

Marine batteries are rated by Amperage Hours. However if it is drawing 40 amps then the battery would last for 25 hours. To measure the amp draw of a motor properly you need a special instrument called amp clams.

Simple multimeters will burn. 50 Amp Circuit Breaker 36 VDC This circuit breaker can be used for a 101 lb. We can calculate the run time if given the 1224v trolling motor amp.

23082012 POER Electric Trolling Motor amp draw figures represent actual on-the-water conditions at different speed level settings with all of the motors wiring LED display and switches in the electrical system while the test measurement is taken The amp draw reduced when the speed level reduced. It happened because simple multimeters are not able to count the amp draw more than 10-20 amp. 06042020 Also question is how many amps does a 55lb trolling motor use.

625 050 20 156 hours. The maximum ampere draw for this motor is 42 amperes. You dont want to draw the battery all the way down to 0 since that will damage it.

24V and 36V motors have a high amp draw and needs multiple batteries in series to meet the power required. 100 amp hour rated battery divided by a 25 average amp draw 4 hours of run. 23082012 A electric trolling motors amp draw refers to how much amp max input electric current a motor draws at a given speed while being operated.

This assumes of course that you have wire gauge and battery reserve to provide that kind of amperage. 05032018 Lets assume my motor is the Endura 30 mentioned above and I troll at speed 2 which is 10 amps draw. 08102020 The maximum ampere draw for these motors is 30 amperes and 42 amperes.

If you use the trolling motor for 6 hours at average 50 load of 20 amps the trolling motor will then require a battery load of 120 Ah. Now you can find out how long your trolling motor will work. 01062020 To use an example a 55 lb thrust motor unit has a peak power draw of 40 ampsIf you use the trolling motor for 6 hours at average 50 load of 20 amps the trolling motor will then require a battery load of 120 Ah6 hours X 20 amps120 amp hours.

This means that a 40 amp-hour battery will last about one full hour of full-throttle trolling. 46lbs of thrust roughly draws 40 amps. Wiring two smaller 23Ah batteries in series may work but you would only be able to use your motor for a short amount of time.

Below is a chart showing the max amp draw Newport Vessels trolling motors for your reference. 05072021 Besides that even at the same thrust a 24v trolling motor is more efficient with a lower amp draw than 12v which also makes it lasts longer. To use an example a 55 lb thrust motor unit has a peak power draw of 40 amps.

23082020 Suppose you are using an electric trolling motor by Minn Kota 50 pound thrust at a speed setting of 2 and its drawing out 20 amps. A batterys amp hour rating divided by the average amperage draw of the motor. 6 hours X 20 amps120 amp hours.

If a trolling motor runs at low speed and pulls solely four amps the battery will last up to 100Amp hour rating4 Amps 25 Hours. 19062019 This is why most 24V or 36V trolling motors use 50 Ah batteries or larger. 50 Amp Circuit Breaker 24 VDC This circuit breaker can be used for a 70 lb.

Amp Rating Amp Draw. This includes the leads leading from the battery to the motor which have to be taken into account. Battery amperage hour rating and a motors amperage or watt draw.

Divide that number into your battery voltage 12V Thats how many Amps it will draw. 25032021 So lets say you already know your battery amperage draw. Measure the resistance between the leads.

An electric battery with a 115 Amp Hour Rating can beat a 100 Amp-hour rated battery in terms of endurance. Battery capacity say 115 amp-hour. 29032021 The motor started but no one knew the amp draw.

In order to approximate how long a certain motor will run on the water you simply take the batterys amp hour rating and divide it by the amperage draw.
