How To Check Amp Draw On Trolling Motor

If y'all are wondering how long your electric trolling motor will last, so you need to know about your motor amps .i.e.

• How many amp hours does your battery support?
• What is your amperage depict?
• How many hours will your motor operate?

These questions are similar to how y'all discuss your car issues, such equally what gas mileage does information technology get or what is the chapters of its gas tank. Let'southward kickoff with a motorcar battery'southward example to solidify your understanding of the trolling motor'south battery.

How The Battery Works

The function of a battery is clear to anyone who is a boat hobbyist, but not everyone knows how it operates when it comes to unlike types. The motor bombardment is used to store and concord energy for use.

The batteries used in cars are known as lead-acid batteries – comprising pb plates submerged in acid. Usually, these batteries fall in the category of flooded batteries, where the acrid acts as a liquid that can flow easily within the bombardment casing.

Oft, people don't recognize that there are multiple types of car batteries. Yet, this fact is overlooked due to their similarity in looks.

Next, let's larn almost the battery measurements, including cranking amps and amps hours. Cranking amps (CAs) are the number of amps delivered by a battery in 30 seconds at 32 degrees Fahrenheit.

Cranking common cold amps (CCA) are similar, but they are recorded at 0 degrees Fahrenheit. CAs work best when it comes to short bursts of intense usage like starter motors.

Amp-hours refer to the number of amps delivered for a stock-still number of hours. For example, a 100 amp hr battery consumes 1 amp to deliver 100 hours, or 20 amps to evangelize five hours. The formula is simple:

Amp x Hours = Amp Hours

Yous'll as well notice RC or Reserve Capacity in place of amp-hours in some batteries. RC represents the number of minutes a fully-charged battery delivers in around 10.v volts at 80 degrees Fahrenheit while drawing twenty amps.

You can convert RC to amp hours by using the following formula.

Amp Hours = RC/2.4

Automobile batteries have lead plates that comprise multiple drilled holes. This design aims to increase surface contact with the acid to generate maximum energy in a brusk period of time.

All the same, this also depletes the battery speedily. Cranking amps are used to measure the ability of car batteries. They are ideal for applications that need brusque bursts of power.

Deep cycle batteries contain solid plates. This is why they last longer and are more stable. Amp-hours or RC ratings are used to measure these batteries.

They are mostly used for applications that crave a steady power draw – motors in wheelchairs, golf game carts, and electric trolling motors.

Marine batteries are by and large a hybrid betwixt both types of batteries. These plates contain a few holes, only not equally much equally car batteries. They are used to start your motor with CA and offer support for a steady current draw for uses like electric downriggers.

Commonly, these batteries are not used with trolling motors, particularly for extended periods. In most cases, they are measured in terms of CA or CC, whereas Amp Hours and RC are also used once in a while.

Keep in mind, bombardment labeling isn't e'er representative of a strict standard. Hence, read the numbers carefully while y'all are choosing a battery. Keep in mind that batteries come in dissimilar sizes. Therefore, information technology should fit where you lot place it.

In the case of trolling motors, it's better to get alee with a deep wheel bombardment due to the college number of amp-hours or RC, thus ensuring that your motor will run longer.

Subsequently some fourth dimension, your bombardment starts to wear out. It can happen due to over-discharge, poor maintenance, or simply age, and your battery fails to deliver the expected amp hours.

What is your amperage draw?

What you actually need to know is how many amps does an electric trolling motor draw or your trolling motor. A Minnkota 80 pound thrust motor has a maximum amp draw rating of 56 amps, according to Minnkota. Below we have put together a chart of some common trolling motor amp draws.

Information technology's not like shooting fish in a barrel to discover the verbal amp draw rating of a motor, but you tin can go in affect with the manufacturer past sending them a message if you can't find your amp draw.

Manufacturers usually list your trolling motor'south max amperage draw at startup and on top speed. Therefore, you need to use it as a baseline to gauge draws at other speeds.

This information is very important when building your trolling motor electric system. Because your trolling motor power is supplied via wiring it is essential to use the proper estimate.

What is a Bombardment Banking concern?

A battery banking concern is 1 or more batteries that are connected together. When 2 12 volt batteries are continued together in parallel it will double the amp hour rating.

Connecting two batteries in serial will double the voltage. Most systems with a voltage of 24 or more volts take multiple batteries connected in series.

How Long Will an Electric Trolling Motor Run on a Bombardment?

To determine how long your motor will run at maximum speed take the battery's amp hour rating divide information technology in half, and so split up the result past the maximum amp depict. Your result is the number of hours your battery will terminal at full speed, however, most people shouldn't utilise their motor in a higher place 50% power (thrust).

Permit's consider that you have a deep bike bombardment banking concern with an amp hour rating of 100. As specified above, separate it by 2. This means that your battery has 50 amp-hours at fifty pct depth of discharge.

Suppose you are using a 50-pound thrust electric trolling motor by Minn Kota at the maximum speed setting and it'due south cartoon out 50 amps. In this mode, yous have around 1 remaining hour every bit per the post-obit calculation.

100 x .5 / l = ane hour -OR- (battery amp hours) x .v / (motor amp depict) = hours

Exercise note that we used maximum thrust in this example. If you are running your motor constantly above fifty percent thrust you demand a larger motor.

At l percent thrust, nigh motors perform at peak efficiency and will draw way less than half the maximum amp draw. The motor in our instance has been tested to describe under 40 percent or 20 amps, but that also depends on the model'southward speed control.

We recommend a divide battery for electronic, such as electric downriggers or fish finders, just if you don't it will also cut the ability bachelor for your electric motor.

Conditions Impact

Keep in mind that weather and h2o tin can have a substantial impact on your battery's performance. A motor that requires 10 amps to motility your boat at medium speed in stable weather may require 20 amps for moving the same boat in stronger winds. Therefore, if y'all are going to use your motor ofttimes in stormy or windy conditions, you need to go along these factors in mind.

Larger Motors

Larger trolling motors offering the same thrust as smaller motors while drawing fewer amps. It helps to increase your run fourth dimension. If you desire your boat to run for extended periods, it's a good idea to purchase a 24v motor, such as the 24v Minn Kota.

Final Thoughts

Hopefully, this article helped you to gain an understanding of how many amps a trolling motor uses. A bones understanding of amp describe and battery amp hours can go a long way in helping you calculate your time on the water.
