You must have heard or read about stories of lithium-ion batteries catching fire or exploding, for example, a smartphone, tablet, or electric scooter. My preferred alternative is to connect two 12-volt batteries in series. Two lighter batteries are also easier to carry than a single large one.

Below, we’ll get into the specifics of each, making your decision easier. As mentioned earlier, I brought this motor out to sea for 8 hours straight. Then, once I got home and put the battery on charge, it was still well above 90% power.

Now, granted, a Garmin Force is very good at managing power consumption when on Anchor Lock. I was doing that a lot and used almost nothing out of my RELiON system. I’m somewhat amazed how little these RELiON batteries have to be charged. An hour on my charger most days, and the system is fully charged again.

It utilizes an absorbent glass mat which not only absorbs vibrations, but it also protects the battery from leaking. Another great design feature is that battery’s grid is made of tin alloy to keep the battery in excellent working condition and to give it a long life. VMAX 12v battery uses an electrolyte suspension system, which consists of an absorbed glass mat that absorbs vibrations. It has a lead plated silver terminal that helps reduce power loss and ensures that you get the power that you need to run your boat. The D34M has CCA ratings of 750 amps, which is more than adequate to start just about any outboard.

It charges the battery fast enough to be back on the water in about 4 hours. We’ve also tested the 24V 80Ah battery as a single battery for a 24-volt trolling motor, and it’s been super impressive as well. The batteries are extremely well made, manage power terrifically and charge fast. We are reassured that any issue that might come up will be handled swiftly. Now, if your motor draws 40 Amps at full speed, those 40Ah will power your motor for 1 hour. Some battery manufacturers insist on using dedicated lithium battery chargers.

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.

This also means the battery is mountable in various positions, which is good news for anglers who need to maximize space on their boat. It weighs just shy of 64lbs and measures 12.17” x 6.61” x 9.16”, so bear this in mind if you’re short on space on your boat. That kind of amp drain will kill most lead-acid batteries, particularly a starting battery.

Unlike starter batteries that deliver short bursts of energy, these 12V lead-acid batteries are perfect for applications like recreational boating where consistent energy is crucial. Whether you’re searching for reliable power boating accessories or need dependable marine equipment, deep-cycle batteries are essential. Regular car batteries can not deliver the maintained power supply that deep cycle batteries are built to provide. It will destroy the battery, and likely ruin the trolling motor to boot. Each trolling motor provides a certain amount of thrust power (rated as pounds of thrust). Most trolling motors are built in either 12, 12/24, 24, or 36-volt models.

Here, I will try to compare the 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.
