Here, I will try to compare the Marine Battery batteries and highlight the main advantages of lithium batteries. A proper choice of a battery for your trolling motor is essential. The battery type means choosing between an FLA, AGM, or li-ion battery. FLAs are becoming increasingly rare, while li-ion batteries tend to be very expensive, although they are small, light, and charge quickly. Li-ion batteries are often just plugged directly into an AC outlet and charge in a matter of 2-3 hours.
Why Is Thrust Important?
Lastly, the lithium battery is supreme due to its quick charge, lengthy runtime, and lightweight. The VMAX MR127 12V 100 Amp Hour Deep Cycle battery is our best overall pick. This is an AGM (absorbed glass mat) deep-cycle lead acid battery. These are often used when a reliable and maintenance-free power source is needed, and the VMAX is precisely that. With 100 Amp Hours, you can motor all day and be equipped with your favorite accessories. Balancing performance, construction, and cost, the Optima OPT 8016 takes the prize for the best trolling motor battery.
Trolling Motor Batteries
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.
A 24-volt trolling motor needs two 12-volt batteries, and a 36-volt trolling motor needs three 12-volt batteries. Before you buy a trolling motor battery, you first need to know your trolling motor’s voltage and max amp draw. Think about how a phone battery can drain and recharge a dozen times without dying.
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.
Here’s a great 24v battery by Ampere Time, which has exceptional quality with higher energy density. The Ionic Deep Cycle Marine Batteries is the best lithium-ion battery of 12 volts and 50Ah, which powers the boat well without worrying about running out of charge. Apart from being recyclable and maintenance-free, this battery’s life cycle is great with the speed of charge. You may select any brand that offers warranties up to 3 to 5 years and has a sturdy, good build quality, and excellent service life of 8 to 10 years. The wet cell batteries are affordable, and if they are adequately maintained, they last for a long time.
The larger the fuel tank is, the more fuel it is able to store and the more energy it can provide to the engine. A larger trolling motor will require more power; therefore you will need a larger battery. You might think that you’ll save some money by going with a cheaper battery, but you’re using it as your transportation over water. Most anglers won’t like carrying trolling motor batteries by hand.

With an expected lifespan of 8-10 years, this big, high-capacity battery may well outlive your trolling motor. Yes, AGM batteries are widely considered to be better than wet cell batteries. This is because it has double the lifespan of a wet cell battery, and charges faster and fuller, while also requiring no maintenance due to having an enclosed body.
The electrolyte suspension system absorbs electrolytes without contaminants for pure power transfer. Heavy-duty, tin-alloy cells improve performance in floating or cyclical charging. Before putting on charge, always check the level of the electrolytes and that they are below the level of the splash barrel of the split ring. If the water levels in the battery are low, top them up using either distilled or deionized water only.
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.
When compared to the competition, the battery has never failed and outlasts and outperforms in every metric. You will pay a premium for that, but boaters say if you want to find peace of mind and know that you are not going to get stranded far from the boat ramp, the Odyssey battery is for you. So make sure that you buy the right charger for your batteries even if they are expensive.
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.
If you need a compact battery that won’t let you down, this is the trolling motor battery you want. One of the best 100Ah deep cycle batteries on the market, it may cost more than most other 100Ah batteries but it shines in its performance. This an exceptional quality battery that is highly recommended for anglers that want to spend many hours trolling at various speeds without worrying about the battery dying. While the 35Ah battery can handle up to 40lb trolling motors, it tends to perform best with motors ranging from lbs. When paired with these motors you can expect as much as 5 hours of run-time depending on the speed settings. A trolling motor battery can be either a dual-purpose or deep cycle, both of which gradually discharge electricity over long periods to ensure the motor has enough power. [newline]Also, keep in mind that all the batteries you connect to your trolling motor battery need to be healthy or else the whole set is going to behave like the weakest battery in the bunch.
Prioritize batteries with built-in Battery Management Systems (BMS) for safety and marine certifications like IP67 for water resistance. The AGM is placed between the specially formulated plates inside the battery and absorbs the electrolytes creating a safe and spill free battery. This battery is designed to provide up to 4 hours power for a 40 lb motor and up to 9 hours power for an 18 lb motor. It is built with heavy duty lead tin alloys to ensure high performance and extended service life, even after repeated discharges.
