What Size Battery For Trolling Motor On Kayak?

Choosing the right battery size for your kayak trolling motor is crucial for optimal performance. A good rule of thumb for starters is a 12V battery rated with a capacity of 30 to 55 pounds of thrust. Most 30- to 55-pound-thrust trolling motors call for a 12-volt battery, while to run the motor all day, use at least a 50-Ah battery.

Lithium-ion batteries are the new kids on the block, offering a significant advantage in terms of weight and size. They are typically sufficient for standard trolling motor setups but may be more suitable for extended trips, heavier kayaks, or long distances upriver. Most kayakers will be looking for a trolling motor with 30 to 55 lbs of thrust, so they should likely use a 12v 30Ah battery or 12v 50Ah. If you have a lot to power, you can also run batteries in parallel (parallel adds battery capacity, run time).

The most popular battery at only 14lbs is the 60Ah LiFePO4 battery, which is similar to the capacity of a group size 27 AGM or better than most group size 31 batteries. Kayak trolling motors typically run on a standard 12V marine battery, and they are easy to control, self-install, and cost-effective. However, lithium-ion batteries are the best type of battery out there, as they are lightweight, compact, charge quickly, and last a long time.

When buying a kayak trolling motor battery, consider factors such as amp hour, battery type, and compatibility with other motor sizes. Lithium-ion batteries are the best type of battery out there, as they are known for their durability and affordability.

How long will a 12V 35ah battery last with a trolling motor?

If the 35 Ah battery is a lithium battery you should get almost all of it’s stated capacity, so you could run about an hour or more on speed “5”. Speed 1 uses 8 Amps/h so>4h, 2-10A/h so 3.5h, 3-14A/h so >2h, 4-20A/h, and 5-30A/h so >1h.

How long will a 50 amp hour battery last on a trolling motor?

Field Tests. Many of our customers can comfortably run their trolling motor and other accessories for a full day fishing trip with our 50Ah models. With our 100Ah models, many customers report 2 or more full days of fishing before needing a recharge.

Conclusion. Determining the running time of a lithium trolling motor battery before needing a recharge requires taking into consideration the capacity of the battery, the power draw of the trolling motor, and other electrical demands on the battery. By doing some calculations, you can get a good estimate of the running time of your battery and plan accordingly for your boating or fishing trips.

It is important to note that the actual running time may vary depending on conditions such as temperature, battery chemistry, and other factors. To ensure the best performance from your battery, it is recommended to follow the manufacturer’s guidelines for charging and maintenance.

How long will a 100Ah battery run a trolling motor?

Calculating Running Time. To calculate the run-time of yourlithium trolling motor battery, you can use a simple formula:Run-Time (hours) = Battery Capacity (Ah) / Total Power Draw (A). For example, if your battery has a capacity of 100Ah and the power draw of your trolling motor is 20 amps, the run-time would be calculated as 100Ah / 20A = 5 hours. However, it is important to note that this calculation does not account for other electrical demands on the battery. To obtain a more accurate estimate, you need to factor in the power draw of all additional components and add it to the trolling motor’s power draw. For instance, if a light draws 5 amps and a fish finder draws 2 amps, the total power draw would be 20 amps + 5 amps + 2 amps = 27 amps. Dividing the battery capacity by the total power draw, the run-time would be calculated as 100Ah / 27A = 3.703 hours, or approximately 3 hours and 42 minutes.

Field Tests. Field tests and customer experiences have provided valuable insights into the practical run-time of trolling motor lithium batteries. Many customers report being able to comfortably run their trolling motors and other accessories for a full day of fishing with50Ah lithium battery models. With 100Ah models, customers have reported running their setups for two or more full days before needing to recharge. However, it is important to keep in mind that actual run-time may vary depending on factors such as temperature, battery chemistry, water conditions, and individual usage patterns. Adhering to the manufacturer’s guidelines for charging, maintenance, and storage will ensure optimal performance and longevity from your battery.

Maximizing Battery Performance. To maximize the performance and run-time of your trolling motor lithium battery, consider the following tips:

How long will a trolling motor battery last on a kayak?

So, with a 100Ah lithium battery and a trolling motor drawing 25 amps at maximum speed, you can expect around 4 hours of runtime. Keep in mind that this is just an estimated duration, and actual runtime could vary depending on the conditions and how the motor is operated. It’s also important to consider that constantly operating a trolling motor at maximum speed may not provide the maximum runtime, as lower speeds tend to draw less current and could potentially prolong the battery life.

How Many Years Do Trolling Motor Batteries Last?. As you may know, there are several types of trolling motor batteries available. The most commonly used type is the Lead Acid Wet Cell battery. This battery is known for its affordability and consists of compartments filled with a mixture of water and sulfuric acid. With proper maintenance, a Lead Acid Wet Cell battery can last around 3 years or even longer depending on usage and other factors.

On the other hand, Lithium Iron Phosphate (LiFePO4) batteries have gained popularity due to their impressive lifespan. These batteries can handle anywhere from 3000 to 5000 charge cycles. Some high-quality LiFePO4 batteries like LiTime have the life cycles around 4000-15000. To put it into perspective, if you were to go fishing all day for around 300 days each year, you would only need to charge it once a day. This means that a LiFePO4 battery could potentially last you 10 to 15 years or even more.

How long will a 50Ah battery run a trolling motor?

4. How long will a 50Ah battery last on a trolling motor?. A 50Ah battery’s duration on a trolling motor depends on the motor’s power consumption. However, for a motor drawing 10 amps, the 50Ah battery will approximately last 5 hours. Always account for efficiency and never drain completely.

How many Ah for a kayak trolling motor?

For your kayak’s trolling motor, you’re going to want a battery that has more capacity. Most kayakers will be looking for a trolling motor with 30 to 55 lbs of thrust, so you’re probably going to need the 12v 30Ah battery or 12v 50Ah.

If you have a lot to power, it’s good to remember that you also have the option to run batteries in parallel (parallel adds battery capacity, run time). In fact, you can go up to four in series with any of our 12v batteries to run 12V, 24V, 36V or 48V systems. So if you need more than one, that’s no problem either.

Now that we’ve covered how to choose your kayak battery, let’s talk about how to use it.

How long will a 60ah battery run a trolling motor?

Full single day of run time. A single Dakota Lithium 36V 60 Amp Hour (Ah) battery will power a trolling motor for a full day of runtime in river current. On a lake, or low power setting, some anglers report 2+ days of run time.

What type of battery do I need to run my trolling motor?. Most electric trolling motor will operate with any deep cycle 12-volt marine battery. But for the longest run time and lifespan we recommend lithium iron phosphate (LiFePO4) batteries. Here’s 5 reasons why:

• Dakota Lithium LiFePO4 batteries will provide double to triple the run time. More run time means more fishing time.
• Dakota Lithium batteries last 5X longer and will need to be replaced less often. Providing peace of mind and greater lifetime value.
• Dakota Lithium weighs 60% less than deep cycle lead acid batteries. Less weight means more maneuverability and speed. And the batteries are easier to carry when you need to charge them.
• Dakota’s lithium iron phosphate works down to negative 20 degrees Fahrenheit (-29 Celsius) meaning you can power your boat in the summer and your ice fishing rig in the winter.
• You need less batteries when you use a Dakota Lithium. Lithium iron phosphate has a flat voltage curve. That means that the voltage does not drop as you use the battery. You get all the juice down to the last drop. Historically if you power a trolling motor with a deep cycle lead acid battery you would only be able to use half of the capacity of the battery before the voltage is too low to run the motor. With Dakota Lithium you can use all of the power of the battery, meaning that a 100 Ah battery from Dakota Lithium is equal to 200 Ah in lead acid batteries.

What size battery do I need for my kayak?

• Voltage: The battery voltage should match the voltage requirement of the motor. Most kayak motors use 12V systems, so a 12V battery is usually the best option.
• Current (Amperage) rating: The battery’s current rating should be equal to or greater than the maximum current draw of the motor. This information can be found in the specifications of both the battery and the motor. (If you are still unsure, please give us a call or a message on our chat function)

Technically the answer to this question is yes, but we don’t recommend it. You may experience interference on your fish finder if you run both your motor and your fish finder off of the same battery. However, fish finders and smaller electronics require much less of a power draw, so you can purchase a much smaller Ah battery to power your additional electronics.

At Eco Fishing Shop, we carefully choose batteries that work best with kayak fishing accessories and motors. In the end, it comes down to finding the best match for your needs. If you plan onparticipating in longweekends or tournaments, opting for the bigger 100Ah batteries will allow you to fish a weekend tournament without the need to recharge your battery. If you are more of a casual angler looking to get out once a weekend and won’t be pushing your motor to its max, a smaller 54Ah or 60Ah would provide more than enough power.

How many amps does a 12V trolling motor draw?

At 12V the Amp draw would be (1Hp / . 75% x 746W = 994.66Whr / 12V = 82.8A). If you wanted to operate a 1HP 12V trolling motor for 1 hour, you would need an 82.8AH 12 V energy (battery) source.

Electric trolling motors are most often rated in horsepower (HP). One electrical HP is equal to 745.7 watts (W).

A 1 HP motor “cannot” use less than 746W (rounded). If the motor draws 1000 W, the motor would be 75% efficient (accounting for the prop drive shaft and balance of system losses). You should always account for the efficiency of the motor and system when calculating your battery energy storage (capacity) needs.

Horsepower is a unit of power, while kilowatt-hours is a unit of energy. To go from horsepower to kilowatt-hours, you need to know how long the power is needed.

What size battery do you need for a trolling motor?

Selecting Battery Quantity. The number of batteries needed is determined by the trolling motor. If the motor is 55 lbs. of thrust or less, you will need 12 volt battery. If you have a motor with more than 55 lbs of thrust up to 80 lbs. of thrust, you will need 12 volt batteries for a total of 24 volts. If you have a motor with more than 80 lbs of thrust you will need 12 volt batteries for a total of 36 volts. If you have an E-Drive motor, you will need 12 volt batteries for a total of 48 volts. If you have a 24 volt, 36 volt, or 48 volt motor you will need to connect the batteries in series. This link will walk you through a series connection. The chart below will show how many batteries and the voltage needed by thrust.

Selecting Battery Group Size. The type of battery you choose will be affected by the features you want and available space in your boat. Larger group size batteries are larger in physical size and usually have a higher Ah rating. The chart below shows average runtime based on the Amp hour rating of the battery and generally associated group size.

Battery Types. Trolling motors can be used with Flooded Lead Acid batteries, AGM batteries, Gel batteries, and Lithium batteries. The different types of batteries have different features that may affect your battery choice.
