What to Look For in a Trolling Motor Battery: (Buying Guide)
We suggest selecting a 12-volt deep cycle marine battery with at least a 110 amp hour rating, usually a group 27 size battery. The higher the amp-hour rating, the longer run time you can expect.
If you don’t find any amp hour rating, select a deep cycle battery with a minimum of 180 minutes reserve capacity.
Volt System of Trolling Motor When you want to operate small and medium trolling motors, you need to use a single 12v marine battery.
On the other side, if you desire to conduct a larger trolling motor, you have to use larger 24v and 36v systems, and you may need to use 2 or 3 marine batteries according to your requirement.
Usually, vibration resistance means lessening vibration from the upper range to the lower range. We can define vibration resistance as follows: “Vibration resistance specifies the acceleration or amplitude in a defined frequency range where no malfunction or damage occurs.”
Vibration resistance provides information about the robustness of the mechanical design of a device.
The shock resistance is important for the devices in operating and transporting conditions. We find the definition of vibration resistance and method of evaluating vibration in IEC 60068-2-6 and IEC 60068- 2-64. we can perform a vibration test on operating devices.
You can find more information about vibration resistance in the PULS data sheets or in the individual vibration test reports.
Amp Hours (Ah)
Usually, manufacturers design Deep cycle batteries with the rate of amp-hours (or ampere-hours) — a unit that measures the total amount of charge inside the battery. It naturally allows a single amp of current to discharge for a period of one hour.
In short, the number of amp-hours raged in deep cycle batteries indicates how much electricity it can store. Since this determines the time that the battery can provide energy for a trolling motor, it’s one of the most important metrics to look for in a deep cycle battery.
This unit isn’t always available for dual-purpose batteries. So, it is rather difficult to calculate the total amount of time for which they can power a trolling motor.
Naturally, the measurements of small batteries are 25 to 50 Ah, while larger deep cycle batteries can reach up to 100 Ah.
Nowadays, there are many types of batteries in the market. Most of the time, the buyers don’t pay attention to the type of battery they need. Even sometimes, they don’t think about the effectiveness and quality of the batteries.
It ultimately can result in low quality, reduced performance and higher maintenance costs.
If you want to get maximum power from your motor, we suggest you pay special attention to the type of battery that you will buy. You must research beforehand what type of battery is suitable for your boat. The main three types of trolling motor batteries are:
- Wet Cell Batteries
- AGM Batteries
- Li-ion Batteries
The size of the battery is an important factor for the trolling motor. The power necessary for a trolling motor depends on the size of the battery. Battery size determines how much power they can hold and deliver.
Standardly, in metric units following the law of thumbs, a trolling motor of 75 pounds thrust (Comparable to 746W or 1hp), every 200 pounds of your boat’s total weight would require 5 pounds of thrust.
Typically, trolling motor batteries come up with 12volts, 24 volts, and 36 volts. A 12 volts battery consuming almost 720w of power is suitable for the boats that are less than sixteen feet.
The weight of the battery is another important aspect. If you have a small trolling motor, comparing it to a heavy battery will immensely weigh it. Typically, too heavy battery can slow down the speed of your kayak or boat. Besides, it is difficult to carry a more substantial battery.
However, if your kayak has a large weight capacity, say 500 lbs, you can use a 40-50 lbs battery, and that would not be a concern.
Most of the batteries weigh between 20-50 lbs. We recommend that you should choose the cells below 30 lbs if it can provide sufficient power for your boat. It would be an unwise decision to buy a lightweight battery if it does not supply the amperage you need.
Cold Cranking Amps
Cold Cranking Amps determines the amps what the battery provides in the first half-minute while it powers up at 0 deg F. It is quite an important feature as your battery might consume a lot of power to start up.
This might hamper its reserve capacity afterward, as it will lose an extensive amount of power in the starting.
Battery Cycle Life
Cycle life is another important option for trolling motor. Cycle life may vary depending on the brand. We find that a traditional deep cycle battery might last approximately two years, but an AGM deep cycle battery will last between three to four years.
The cost of AGM’s battery is more than standard deep cycle batteries—almost twice as much. So, it may be a difficult option for those to buy AGM deep cycle batteries, which are on a tight budget.
The Lifespan of the battery indicates how long it will last or work properly. We have already mentioned, Lithium trolling motor batteries can last for a decade if you keep it under proper conditions while the wet cell batteries last around 2 years.
On the other side, an AGM battery will last for about 4-5 years if you operate precisely.
The Lifespan of the battery depends on storage conditions. If you follow the above tips, you can surely retain the Lifespan of your battery. Excessive heat may quickly lessen the lastingness of your battery.
Afloat cycle demands less charging, so using your batteries for a floating cycle can extend the battery life.
Because of overheating, a deep cycle can often result in damage. In a deep cycle, you will need to use the battery to start the motor which can often waste an extensive amount of power. So, it may require frequent charging and discharging.
Brand or off Brand
The products of a good brand have a great demand in the market. Most of the buyers want to buy the products of renowned brands, and for this, they have to pay extra money.
Moreover, it is a factor of mental satisfaction to purchase the products of eminent brands. Typically, the batteries of good brands serve longer and smoothly if you use them properly.
But keep in mind that purchasing the cell of a renowned brand does not mean that it will last longer. You have to remember some important factors in this case. Most importantly, you have to keep the battery fully charged for a long-lasting trolling motor.
An angler should have a conception about all these issues before purchasing a trolling motor battery.
Names of some renowned Trolling Motors brands are as follows:
- Minn Kota Endura C2.
- Newport Vessels NV-Series.
- Minn Kota Power Drive.
- Newport Vessels Electric....
- Minn Kota Endura Max.
- MotorGuide X3.
- Watersnake Tracer.
- Watersnake ASP.
Warranty is another crucial factor before buying any product. Most of the eminent manufacturers offer a warranty on their products on different tenure.
Depending on the warranty of the producer, many buyers purchase their expected products, and most of the cases, the users of the products or devices are satisfied with the warranty provided by the manufacturers.
But in some cases, the products of lower brands cannot satisfy the warranty offered by the manufacturers. So, before buying any product or a device like a battery, the purchasers should gain full knowledge about the quality and the warranty of the products.
What kind of battery is best for a trolling motor?
Usually, deep cycle batteries are the best for trolling motors. But the capacity of the deep cell battery is as important as the battery itself. Capacity means how long it can provide power to the trolling motor on the water.
We can calculate this by dividing the Ampere hour of the deep cell battery by drawing the trolling motor’s power.
The higher the Ampere hour (Ah) of the battery, the longer it will serve. We can measure the trolling motor’s draw power as the amount of power consumed at maximum speed. Take, for example- a trolling motor that has a drawing power of 15amps at maximum speed, and your battery is 100Ah. Now divide them through equal 6.7 hours on the water.
You should also consider the volt of your battery and the size of your boat before purchasing. A bigger boat needs a bigger voltage battery to work effectively.
Although there are different battery categories available in the market, lithium batteries are better than those of other batteries. So, I am going to provide you with the advantages and disadvantages of these batteries below.
Advantages of Trolling Motor Batteries
Lithium batteries have greater benefits than conventional wet lead-acid, absorbed glass mat (AGM), and sealed Gel marine deep cycle batteries.
Longer lasting power is the most remarkable advantage among these. In order to get 36-volt trolling motor power, you have to use three 12-volt marine batteries in a series.
Three 100 Amp Hour (AH) lithium batteries in a series can increase the running speed of trolling motor at the same speed roughly twice as long as a series of three conventional 100 AH marine batteries.
Also, Lithium batteries do not lose voltage as it draws them down. They can provide power two times more than conventional marine batteries and keep your trolling motor running at full strength throughout survival.
Moreover, a discharged lithium battery doesn’t create any harm if you recharge repeatedly, and you can recharge it to its full strength. Furthermore, you can discharge and charge a lithium battery five or more times than conventional marine deep cycle batteries.
Disadvantages of trolling motor batteries
If you need not upload the batteries in your boat, you must remove them for charging and for safety reasons; even if you leave your boat chained or bertha tree.
It is quite a disturbance to load batteries in the car after each trip, especially if you use two or three at the same time. But if you use a 12-volt battery, it is not a major hassle for you.
If you require enough power to remove children in the momentum behind the boat on a tube or skiing, do not forget to get one because you will go nowhere.
If you need higher power engines, you must carry extra weight in two or three heavy marine batteries. Make sure you have enough room to place the batteries, and if your boat is small, the pressure will not affect its performance.
Although good batteries are expensive in most of the cases, they last at least four to five years. Sometimes, it is difficult for someone to spend extra money to buy expensive batteries.
Mighty Max is one of the well-reputed brands for trolling motor batteries. They produce batteries with high Their ML 18-12 battery weighs just 12 lbs, which is by far the lightest trolling motor battery on our list.
You can easily operate a Minn Kota trolling motor with any lead-acid, deep cycle marine 12-volt battery/batteries. If you want to get excellent results, you can use a deep cycle marine battery with at least a 110-ampere hour rating.
Typically, a 55 lb thrust motor unit requires a peak power draw of 40 amps. If you run the trolling motor for 6 hours at an average 50% load of 20 amps, the trolling motor will need a battery load of 120 Ah.
No, manufacturers do not recommend car batteries for running trolling motors. It can ruin or damage your motor.
As a general rule, you can use three 12-volt marine batteries in a series to gain 36 volts to run a 36-volt trolling motor. Three 100 Amp Hour (AH) lithium batteries in a series will provide you with the same speed around twice as long as a series of three conventional 100 AH marine batteries for running a trolling motor.
