Trolling motors use deep cycle batteries, and the car trolling motor battery 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.

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.

Even when stored for long periods of time in adverse weather conditions, the battery turns right over when charged. The AGM design keeps all the components safe and snug inside the case preventing any leaking or corrosion. Thanks to the AGM design of the battery, it is entirely maintenance-free and requires no checking of levels or time-consuming corrosion prevention.

Keep in mind the amp draw is just an estimation based on our research to give you a rough idea of what to expect. Lithium batteries usually come with a longer warranty, often up to five years full coverage and sometimes as much as 10. It was my most pleasant surprise in the group as a lesser known brand.

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.

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.

Also, as an AGM battery, the contents are completely sealed so there is no need to worry about leaks and you can mount it in various positions. In fact, as a more compact battery (9″x 5.5″ x 8″) it is a good choice for boats that lack space. The lifespan of the battery will vary depending on how you use it. Again, the weight of the vehicle and the speed of the motor will influence the amp draw, so bear this in mind when looking at ampere-hours.

A 12V trolling motor requires just one 12V battery; for 24V and 36V systems, you will need to connect 2 or 3 batteries in series. More batteries of the same size mean more capacity and more range available. Depending on the voltage of your trolling motor, you will need a different number of 12-volt batteries.

Reasons Trolling Motors Lose Power (explained)

This is the best choice if you don’t want to buy batteries every year. This battery is also user-friendly- it comes with a carrying handle for portability. With this compact but powerful battery, you can enjoy longer trolling motor usage at high speed. It also has a wide temperature range to use in hot or cold weather.

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.

Thrust is typically measured in pounds (lbs) and will give you an idea of how powerful a motor is, the more powerful the motor the more battery power it is going to require. To understand its reserve capacity as a matter of priority over time, it is always necessary to check the current battery. The Odyssey Trolling Thunder battery also has a higher capacity than most trolling batteries. This means the battery will require less frequent charging and last longer on a single charge. This Vmax battery is excellent for trolling under harsh conditions. Anglers won’t have to worry about its maintenance because it is manufactured to have a maintenance-free operation.

All 36v Trolling Motor Batteries

The most common ones are lead-acid batteries, AGM batteries, and Lithium-ion batteries. Lithium batteries, on the other hand, can be regularly discharged to 80% and still last hold the charge after 5 and more years. Remember to factor in any additional electrical equipment that may be using power from the battery while trolling.

If you’re looking for a deep-cycle battery to run your trolling motor all day, there’s no better battery than this. This Optima battery is completely sealed so that it can be mounted anywhere. When it comes to deep-cycle marine batteries and AGM batteries, the Optima 8016 is hard to beat. [newline]The best way to look at the amperage of a battery is to compare it to the fuel tank of a motor vehicle.

Lithium batteries are one of the latest trends for high power and low weight. The Tracker Lithium Super High Output Battery is ready for action. Compared to a lead-acid battery with an average of 270 recharges, the Tracker Lithium can be powered over 5,000 times. It’s also capable of deep cycle usage, adding a little versatility to this package. At $249 for the Group 27 model, this is one of the more affordable batteries for trolling motor use—great for anyone just starting out or anyone who doesn’t want to spend a ton of money.

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.
