These batteries have a slick 24V lifepo4 battery display panel for the status of the battery and an app on Android. Dakota Lithium has been providing stable lithium power for longer than a lot of other brands, and their batteries are some of the most proven in a wide plethora of applications. They offer some of the most robust options as well as, considerably, the widest array of options to fit any scenario or need you could have in fishing. Even their smaller batteries are solid choices for kayak fishing and ice fishing applications as we’ve used them a bunch for both. Lead-acid batteries have significantly lower capacity when discharged fast, known as Peukert’s Law.
Finally, it has low self-discharge rate, which means it can sit for a year without being recharged. It’s not recommended to leave your trolling motor battery plugged in constantly. While lithium batteries have built-in BMS protections, overcharging or maintaining a full charge for extended periods may reduce battery life.
You’ll also need to invest in a charger that can equalize them regularly, essentially delivering a slight overcharge to clean the plates of sulfate crystals. Despite the design improvements and technical wizardry you’ll find in modern deep cycles batteries, they just won’t last forever. Lithium-Ion (Li-ion) – These batteries trade up from lead and acid to carbon and lithium salts to deliver power. The result is that they’re easily rechargeable and generally smaller and lighter than the SLA or AGM batteries of the same power.

Now imagine an athletic adult in the same position, they have a larger body with a more developed physique and therefore swim against the tide with ease. The thrust of your boat is equally as important and makes the difference between a sluggish and difficult journey and a smooth and enjoyable one. If your boat is heavier, it will also change the size of battery that you need. If either your motor or your battery falls short in any way, your boat will not be all that you wanted for it to be. It will be sluggish in the water and may cause you to waste most of your day out fishing; riding to a new spot. According to powerboat manufacturers, trolling boats 14 to 16 meters long should be equipped with a 12-volt battery.
Since this one is designed with AGM technology it requires very little maintenance, a strong powerful turnover, and a fast recharge. This is an excellent battery for serious anglers who care about their fishing. Whether you need one trolling motor battery or three of them, that’s the first guideline, but there’s more to it than that. And of course, if bargain basement batteries aren’t up to snuff in the first instance, you were penny wise and pound foolish. This is a pretty “vanilla” battery, but that’s meant in a really positive way. It’s proven technology, works with a variety of chargers, and will most definitely not break the bank.
Despite offering a lot more power than smaller 35Ah batteries, it is a surprisingly lightweight and compact model. It only weighs 38.5 lbs, which is not much heavier than smaller batteries and often lighter than other 55Ah batteries, highlighting its suitability for small/medium boats. These batteries are leak and spill-proof as well as maintenance-free, just like AGM batteries, and can also be mounted in any position. They are best suited for very deep cell applications such as batteries for electric wheelchairs, RVs, and trolling motors. A good battery will extend the use of your motor and also power other onboard electronics. The right battery will last for many years, so it’s certainly worth investing in a quality battery to get the most out of your trolling motor and time on the water.

With proper voltage matching, smart charging practices, and certified safety features, anglers can achieve 8-12 hours of continuous runtime. Invest in quality BMS-equipped models from reputable brands to ensure 10+ years of reliable service across thousands of charge cycles. Selecting the ideal lithium battery for a trolling motor requires evaluating voltage compatibility, amp-hour (Ah) capacity, weight, charging speed, and cycle life. Lithium batteries outperform lead-acid alternatives with 2-3x longer lifespans, 50% weight reduction, and consistent power output.
The 12.8V 160Ah Impulse Lithium battery will run 5 graphs, plus Humminbird 360 and Active Target 2 modules, all day for several days before needing to charge. It also has plenty of continuous cranking amps to fire a Mercury 250 PRO XS 4-stroke without fail. They charge quickly and hold a charge well with a good lithium charger. With a 12V battery you have 4 cells at roughly 3.2V or something like that to get you to 12.8V. So if one of those cells gets close to its shutoff level, the whole battery is dead.

Note that car battery needs to be inside an enclosed, protected environment, such as under the hood of a car. They’re not designed to be in the open, taking on extra vibrations. It’s important to note that the actual capacity of a battery may vary on various factors, such as temperature, discharge rate, and age. Consider these factors and follow the battery maintenance tips when making a selection.
These are a really good choice if you’re ready to make the leap. They were still going as strong that day as the day I bought the boat. They’re readily available at a variety of retailers and outlets, and even if you’re using “another brand,” you may actually be using Dekas just badged as something else.
By contrast, car batteries work in a pampered environment, and it’s important to keep that in mind. But they require proper ventilation, can leak and spill acid, don’t hold a charge as well in storage, and can be damaged by the vibrations typical in marine use. Unfortunately, battery tech is confusing, and unless you really do your homework, you’ll shortchange your motor and yourself.
With at least 20% of capacity remaining, it can stand from 3000 to 5000 charging/discharging cycles. Apply the test instruments between a battery and motor, measure the voltage and power flowing from a battery, and perform a long-term test to guess if a motor overheats or not. In your boat, a lithium battery works according to its purpose. The electricity inside a lithium battery is produced by the movement of ions (positively or negatively charged atoms and molecule particles).
It is a lightweight and small battery (12.75 x 6.875 x 9 inches and only 29 pounds). As for the disadvantages, these batteries are not that good incapacity. In a lithium battery, the cathode is formed from lithium metal oxide (cobalt in most cases). A good battery can ensure long terms of fishing, minimal maintenance efforts, and safety. This is a powerful product aimed at demanding users who want a battery that lasts for many years. There are cheaper batteries to choose from, but this one will probably outlast most of them by a considerable margin.
At the price, it would be perfect to double up on, and even out the weight on your craft. Although not listed in the title, this 12V battery does employ absorbed glass mat technology and is also completely sealed. Generally speaking, the larger trolling motor battery size (rated by Ah or amp hour), the better as you’ll be sure to get more runtime out of it.
