Trolling Motor Battery Amp Hours

You have a 100-hour battery in a motor that gives 30 amps at a standard speed. The amp hour rating on a battery measures the amount of charge a battery can hold the larger the number the longer it can power a motor.

Therefore you need to use it as a baseline to estimate draws at other speeds.

Trolling motor battery amp hours. Marine batteries are rated on a metric called amperage hours which is an indication of how long a battery can supply a consistent amperage. This unit measures how long a battery can maintain a consistent amperage output. This will give you an estimated battery life for your trolling motor.

In theory if your battery has 100Ah capacity and your motor draws 20 amps of current then you can calculate its run time by dividing 10020 5 hours. However as we said before if you want to keep your AGM in good condition you should only use 50 of its rated capacity. 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.

01012021 Amperage hour rating or amp-hours for short is how long your battery will last on a single charge. Manufacturers usually list your trolling motors max amperage draw at startup and on top speed. 09122015 In more technical terms a 100 amp hour rated battery can deliver 100 amp hours of current to a trolling motor.

Motors draw different amounts of current from the battery depending on the motor size and speed it is turning. Click to see full answer Hereof how many amps does a Minn Kota trolling motor draw. Ideal for deep cycle applications in marine or boating environments where you need lots of power for a long time.

Now you can find out how long your trolling motor will work. Trolling motor batteries are typically between 35 and 125 amp-hours. Using the formula youll get 33 hours.

Marine batteries are rated by Amperage Hours. 100 amp hours AH of capacity is optimal for larger 12V trolling motors. 25032021 So lets say you already know your battery amperage draw.

What is a Battery Bank. 06042020 But small trolling motors usually draw about 20 amps per hour at 12 volts. Here is a graph to about trolling motor battery run time.

04022021 A good trolling motor battery is durable and can store a large amount of charge. 09122015 Keep in mind that trolling motor run-time is not an exact science but the following parameters will help you approximate your potential run time. The larger the rating the more power the battery can hold and the longer it will be able to power a motor.

Its a good idea to use the maximum draw used for higher speeds. 10012018 Most trolling motor batteries fail due to lack of proper charging. 6 hours X 20 amps120 amp hours.

01062020 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. How much energy a battery can store is measured in amp-hours. A more important number to look at when selecting a trolling motor is the reserve capacity.

Amp Rating Amp Draw. We suggest selecting a 12 volt deep cycle marine battery with at least a 110 amp hour rating usually a group 27 size battery. Are lithium batteries good for trolling motors.

The Group 24 - 12V 75AH Lithium Battery is ideal for most trolling motors and is widely used by anglers who want enough power to last throughout an entire day of fishing. 23082020 For instance if a motor delivers 30 amps at medium speed with a 100-hour battery your run time is most probably around 33 hours. The higher the amp hour rating the more run time you will receive.

So if a motor was running at low speed and pulling 4 amps the battery should last around 25 hours. The LBP100 features a built-in battery management system BMS that keeps the battery running at peak performance while preventing overheating overcharging and maximizing cell cycle life. That is 100 of the battery capacity drawing that amount will significantly reduce the life of your battery so you should only draw a maximum of 50 amps from a 100 amp hour battery.

The larger the amperage hours AH rating the longer it will last and more power it will be able to hold. With this information just divide the amp hour rating on your battery by the amp draw of your motor. 100 amp hour rating 4 amps 25 hours.

Things that affect amp-hours include the type of battery speed of travel the weight being carried the water conditions temperature and style of trolling motor being powered.
