If you want to avoid disappointment, you Marine Battery want your lithium battery to come from a reputable source, with a warranty and support. You can also charge your lithium battery using your boat’s outboard or inboard engine. Weather and water conditions will also affect how long your motor will run. It is harder to push a boat against the current, choppy waters, or into the wind, which means a higher current draw and shorter run time. We recommend to connect three 12-volt lithium batteries in series to create a 36V battery. Amper Time is a decent quality lithium battery that comes with a significantly lower price than Battle Born.

Trolling Motor Battery Setup

Batteries are pretty heavy, ranging from pounds, and on a fishing vessel, chances are you’ll have at least two. On top of that, the size is smaller and more portable, allowing for use in almost any boat. The weight is 43.5 pounds, and the dimensions are 10×6.75×7.8 inches. Flooded wet-cell batteries are less expensive, but they don’t perform as well as the other choices. Wet cell batteries can spill acid, so they don’t stand up to vibration well and have to be mounted in a level position.

The Power Series AGM is their top-of-the-line Group 27 deep cycle battery. With improved efficiency and storage, this battery is rated to fish all day and take a beating. The AGM has a higher cold cranking rating and longer reserve time than lower-priced models. Lithium batteries weigh 60% less than equivalent lead-acid models—a 100Ah lithium battery averages 26 lbs vs. 65 lbs for AGM. Reduced weight improves boat stability, fuel efficiency, and payload capacity.

How Many Years Do Deep-cycle Batteries Last With Trolling Motors?

Trolling motors use deep cycle batteries, and the car battery (usually the cranking type of battery) isn’t ideal for a trolling motor. For example, if you have a 100 amp hour trolling motor battery, and the motor pulls 40 amps at top speed. The trolling motor battery life should be around 2.5 hours (100 Ah / 40 amps) at top speed.

It provides an Amperage of 100Ah, and this is a 4000+ Cycles Rechargeable Battery, which is a great option for marine activities. It is slightly heavy but other than that, the amperage is 120 Ah, along with a voltage of 12 volts. This trolling motor battery uses the Absorbent Glass Mat (AGM) technology and a valve fixed design. This can be utilized to enclose and indoor conditions without leakage or heavy maintenance. Dual-purpose batteries deliver powerful cranking amperage for smooth and easy starting of the motor and have a low amp draw service.

You can’t usually ship wet cell batteries, so you’ll have to pick these up in-store. This VMAX battery is rugged and capable of withstanding pretty extreme conditions. Reviewers note that the battery holds a good charge and lasts long enough to stay on the water all day.

Especially when compared to a more expensive battery, which has endless possibilities. When making your final buy, think about where you’ll be placing the battery and whether you’ll have to add or remove weight to your boat. With that said, you must be conscious about battery placement and weight. If you have two 50-pound batteries on a Jon Boat, plus you in the stern, the boat will run with the bow in the air. You’ll need to find a proper place for the batteries to act as a counter balance.

It’s large enough to power trolling motors all day, delivering the thrust you need to fish hard. Trolling motors with 30 pounds of thrust are often found on smaller boats like kayaks and canoes. The following chart shows the run times at various speeds with different battery sizes. They will degrade over time and not put out as much power in the latter years.

For 24V/36V systems, connect multiple 12V batteries in series using marine-grade wiring. Each trolling motor will be fitted with a 12v AGM deep cycle battery, with low hours of power supply over a long time. CCA rated batteries are cheaper than deep cycle units and they will power your trolling motor but not for long. They are designed to provide large amounts of power over a short period (to start an engine).

Corrosion on your battery terminals can cause total power loss. So be sure to do a preventive maintenance check each time before using. If your battery isn’t running at full strength, you’re losing out on power.

For optimum power efficiency, Pureflow employs the highest-quality lead cells. Installing a battery to the trolling motor can seem like a daunting prospect, however, it is actually a straightforward process that requires just a little knowledge and skill. This means if the battery dies, you’re in a dangerous situation. Spend a couple more dollars upfront or risk the anguish of calling for a tow boat or spending hours paddling into shore. Group size types are not battery types, but they’re considered battery families – the larger and stronger the battery, the higher the number. Customers are satisfied with the battery’s performance, noting it supplies ample power and works flawlessly all day without any issues.

Combined with the dual connection terminals and battery life indicator, this is a very easy battery to use. This Sealed Lead Acid (SLA) battery, which is another name for AGM, is much cheaper but still powerful enough to power your trolling motor over reasonable distances. But, if it fits your craft, this battery will provide years of reliable use. For this guide, we’ve tried and tested the 12 best trolling motor batteries so you can buy with absolute confidence. Trolling motor batteries need to fit the intended watercraft and hold enough charge to get you to where you want to go.

I can monitor my battery’s status in real-time and manage its discharge with ease. The low-temp cut-off protection is another standout, ensuring the battery performs safely in temperatures as low as -20℃. Whether I’m running a trolling motor in the middle of a lake or using it for off-grid power, it’s reassuring to know the battery is protected in extreme conditions.
