Transport of this battery is made easy by integrated carry handles. Lastly, the VMax Lithium Iron battery comes with a 5-year pro-rated warranty. Being an AGM battery means it requires virtually no maintenance and it will handle vibrations without lowering the charge. That’s why we recommend replacing or recharging your whole set of batteries at the same time instead of one at a time.

Its deep cycle design allows for repeated deep discharge and recharge, making it a long-lasting option for all your marine needs.Don’t let a dead battery ruin your day on the water. Invest in the Newport deep cycle battery and enjoy uninterrupted power for all your marine activities. Order now and experience the convenience and reliability of this high-quality marine battery. Built tough, this 24-volt lithium trolling motor battery package gives you the power to fish from morning to night. 50 Amp hours (Ah) of capacity is optimal for larger 24V trolling motors.

These are the abbreviations that matter when you’re looking for battery specs. Any others you see will be related to the product model, and don’t have a bearing on the battery performance (except perhaps for taking manufacturing quality into account). Ampere hours will typically range from 35 – 100 in deep cycle batteries, but can be found in lower and higher hours as well. The higher number meaning the battery can provide more energy (and will be bigger too).

It is then recommended that you install a DC-DC charger between your engine’s starter and lithium batteries to ensure it’s correctly charged. If you have a 24V trolling motor, it makes sense to get a single 24-volt battery rather than connecting two 12V batteries in series. The extra capacity of 200Ah gives you a longer runtime and peace of mind. It also reduces the chance of discharging your lithium battery below 20%, which helps to make it last longer.

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).

For instance, if you pair it with a 60lb thrust motor it should provide around 8 hours on low, 4 hours of power on medium, and just under 2 at high. This battery is one of the best you can get for a 30-35lb trolling motor. While many opt for 35AH batteries for these motors, investing a little more in a battery such as this will significantly increase your trolling time no matter your speed.

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.

Best Trolling Motor Battery: Dedicated Batteries To Keep You Moving In 2025

The warranty provided for your trolling battery will be determined by how and where you purchased it, and whether it was new or second hand. As a general rule of thumb, the majority of providers issue a 5-year warranty with most trolling batteries. This can, of course, be longer or shorter and can be found on the website of the manufacturer. The length of time a battery will produce power for depends on its size. There are 2 things to look at to work out how long a battery will last, these are the ‘Amperage Hour Rating’ and the ‘Motor Amperage Draw’. In technical terms, thrust is the force of flight that pushes things forwards and can be created by both engines and propellers.

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.

When it comes to battery group sizes, there are quite a number of options available. Think of the amperage hour rating when deciding on which size to buy. Lead-acid batteries also heavier than AGM batteries because the lead plates inside are flooded with water. They also need maintenance because you need to check for corrosion as well as the fluid levels. The battery is leak-proof, thanks to the absorbent glass mat inside the battery which also protects the lead plates from grinding on each other. It has a 70% longer life cycle, compared to other similar batteries, and it has 400 cycles at a depth of discharge of 80%.

They’re just using the deep cycle battery to power their trolling motor instead. Other instruments (such as fish finders) can also be powered by your deep cycle battery if desired. Getting your trolling motor supplied with plenty of power doesn’t require you to become an expert in batteries. However, some basic knowledge about deep cycle batteries, and how they differ from car (or cranking) batteries can go a long way.
