Each battery type has its own pros and cons, so it is trolling motor battery not a one size fits all type of choice. For those on a budget, an AGM battery will prove to be best as it provides power, longevity and functionality at a fraction of the cost of a lithium-ion battery. For those who have a generous budget, a lithium-ion battery will prove to be better due to its extended lifespan, lack of maintenance and fuel saving benefits from a reduce weight load. Again, the price of a trolling battery will depend on its size, model and manufacturer. Cheap marine batteries start from around $50 and can go up to more than $2000 for a high-end model.

A single battery with a powerful current of 50A maximum can make a motor working for 2 hours in a row. In general, if you are not sure about a lithium battery choice, we can recommend two more things to do besides consulting a motor producer. The first thing you should know is that the majority of trolling motor producers suggest buying LiFePO4 batteries. It means that Ferrum (iron) stands as a supporting element in a battery.

I still use an Everstart Marine battery for my cranking battery because all it does is start the boat and run my livewells. I keep mine in the YakAttack BackPak Pro Krate along with my Livescope module. I can take the whole crate out and charge and travel with ease. Then I can fasten the crate to my Kayak to keep my battery secure on the water. The ZPRO Lithium 12V 50Ah has been a perfect kayak solution for me.

The water levels are only necessary for non-sealed lead-acid wet cell batteries. When searching for a battery the bigger the AH (amp hours), the more run time you’ll have. Whether you’re a bass boat fisherman or a kayak fisherman, the size of the battery is essential.

Customers find the battery easy to use, with one mentioning it’s convenient to handle in the boat and another noting it’s particularly suitable for older fishermen. Customers appreciate that the battery is relatively light, with one customer noting it weighs less than 40 lbs including the case. Customers are satisfied with the battery’s charge rate, noting that it comes almost fully charged and charges well, with one customer mentioning it charges quickly. It has been tin-plated and has great deep cycling capabilities, around 400 Cycles at a depth of discharge of 80%.

The higher the number, the longer your trolling motor battery will last. Absorbed glass mat (AGM) batteries – this is the most common type of trolling motor battery. Save money, space, and weight with this small, light, well-priced trolling battery.

The Department of Transportation also approves the Odyssey battery for being completely spill-proof. Since 1898, OL has been a leading authority in testing and reviewing hunting gear, fishing tackle, guns and shooting equipment, and much more. We have more than a century-long history of evaluating products, and we’re now bringing that expertise to online reviews. Our editors are experienced outdoorsmen and women, and most importantly, we’re trained journalists.

Customers find the battery performs well with 30lb Minn Kota trolling motors and lasts all summer, with one customer reporting it runs for 8 miles on a single charge. They appreciate its compact size, particularly for small boats and kayaks, and its lightweight design that makes it easy to carry. Customers consider it good value for money and praise its power, with one noting it provides plenty of power for the trolling motor. They find it easy to use, with one mentioning it’s particularly convenient for their Scadden Predator. Deep-cycle batteries are designed to provide continuous power over extended periods, making them ideal for powering trolling motors and supporting marine equipment.

Best Trolling Motor Batteries Compared

Because lithium batteries have a lifespan of 3000 cycles and more, you won’t have to worry about replacing them anytime soon. The recommended charging current for lead-acid batteries is 10-30% of the rated capacity. For example, you shouldn’t fast charge a 100Ah lead-acid battery with more than 30 Amps. A lower voltage means the motor will draw more amps to provide the needed power. On the other hand, lithium batteries will only have around a 3% voltage drop as they are discharged.

Just as the name implies, the starting batteries (aka cranking or starter battery) are designed to start a motor smoothly with short and strong bursts of energy. They are not designed for multiple discharge/recharge and draining it can cause damage. If you are in a hurry, here we’ve compared all popular trolling motor battery options and hand-picked the top 5 that can easily fit in Minn Kota and other trolling motors on the market.

This feature makes this battery incredibly popular among serious anglers on larger fishing boats. This battery has the power to turn over a larger motor among rough waters. They are under warranty for twelve months from the date of purchase. The company recommends checking your charger and panels to ensure they meet the required wattage. If that does not fix your problem, try charging the battery for fifteen hours and reading the voltage meter.

The sealed trolling motor battery can further break down into AGM and Gel types, which often shows in the title tags of the electric trolling motor battery. The flooded electric trolling motor battery (aka wet-cell battery), contain a liquid combination of water and sulfuric acid. They last longer and cost less but needs you to add distilled water regularly to maintain the correct level of liquid.

For instance, if your motor draws 25Ah then the battery will still offer enough charge for around four hours – perfect for most fishing trips on the water. The performance is even better when the motor and boat are smaller, so it’s a fine choice for many types of fishing scenarios. You may want to pick a deep-cycle trolling motor battery with more than twice the amp-hours. Batteries with that kind of power often weigh a lot more, which can wind up taxing your motor more than a lighter battery that offers half the power. Another battery spec you may find on a trolling motor battery is called reserve capacity.

Are Agm Batteries Better Than Wet Cell Batteries?

A lead-acid wet cell battery typically lasts between 2 and 4 years with proper maintenance. AGM and lithium batteries may last longer, with some lithium batteries boasting a lifespan of up to 10 years or more. Whether you’re a seasoned angler or a first-time boat owner, this guide will provide you with all the information you need to select the right trolling motor battery for your needs.

Ideal as a dedicated trolling motor power source, with anything like reasonable throttle settings, you’ll have juice to spare at the end of the day! In fact, many anglers find that they barely make a dent in this battery’s power reserves. It is able to give short bursts of energy if it is a starting battery and discharge slowly, giving a stable power flow if it is a deep cycle battery.

Some EFBs are used in start-stop cars because they have a similar power profile to AGM batteries. Often times you can find this on the battery or the manual if you still have it. A quick good search should also reveal a better way to find it on your specific battery. The only negative thing that is said about this battery is that it’s a little bigger and more difficult to install.

The overall productivity makes lithium batteries better than other battery types, though. It makes it a perfect choice for kayak trolling (minimal weight and dimensions can fit into the smallest boats), but if you need more power – choose something else. With all the advantages, some lithium batteries are quite specific. Some of them cannot be members of the battery series for more powerful motors.

As one of the best 12V 100Ah lithium battery for trolling motor, the battery is perfect for trolling motors with thrust ratings between lbs. It provides up to double the runtime of traditional AGM batteries, while weighing 1/3 less (only 22.16 lbs total), improving boat speed and efficiency. The best marine battery for a trolling motor, according to our recommendation, is the 12volt deep cycle marine battery. It needs to have at least a 110 amp hour rating, and ideally, it should be of 27 sizes.
