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.

This blue top battery has a reserve capacity of two hours, ideal for longer periods of trolling. The absorbed glass design provides the battery with mounting flexibility and ease of use. The battery belongs to group 31, with a CCA of 900 and an MCA of 1125A.

Buying from the most competent brands ensures you spend less time recharging and more time fishing. [newline]If that’s what you’re looking for, always choose the right type of battery. Lithium deep-cycle marine batteries are designed for high-performance, ensuring reliable power for applications including boats, trolling motors and fish finders. These batteries integrate Battery Management Systems (BMS) to prevent overcharging and extending their lifespan. Offering prolonged battery life, they require less frequent charging, providing more uninterrupted time on the water. Optimizing your trolling motor setup requires lithium batteries that balance capacity, weight, and marine-grade durability.

Unlike other types of lithium batteries, LiFePO4 batteries will not catch fire or explode. The biggest downside of smaller lithium batteries is that their maximum current output may be too low in some cases. These small lithium batteries are great for kayaks, canoes, and inflatables. One important thing to know is that you shouldn’t charge lithium batteries in freezing temperatures. That is why it’s recommended to oversize your battery wires when you use lead-acid batteries. A lead-acid battery should only be discharged to roughly half of its rated capacity (Ah), which means you need to get a battery double the capacity you actually want to use.

Totally sealed for life means the unit is clean and safe to handle. Measuring 350 x 170 x 275 mm, the NP is the same size as UItamax’s 100, 110 and 120Ah batteries and therefore makes an ideal replacement for anyone looking for a power upgrade.

It also has cold-cranking capabilities, meaning the battery will function in even the most extreme colds. In addition to its long run times, long life, and high energy density/efficiency, the VMax Li-Iron Lithium battery boasts an advantage over other battery types when it comes to storage. That’s because lithium iron batteries can be stored for up to a year with minimal charge loss. It’s a standard 12V battery with 100Ah, offering lots of charge for both small and large motors alike. Most people tend to use batteries of this size for large boats and motors but it will also perform well on kayaks and smaller vessels too.

With so many options on the market, choosing the best trolling motor battery can be daunting. But don’t worry, we’ve put together this guide to help you navigate the world of marine batteries. After 15 hours of research, I’ve confidently sifted through numerous options and come up with this list.

Gel batteries last longer in hot weather applications and offer remarkable resistance to any kind of leakage and enhance stability with few maintenances. Customers report issues with the battery’s charging capabilities, mentioning problems with both the charger and its functionality. Customers have mixed experiences with the battery life, with some finding it good and working well, while others report that it went dead or didn’t charge completely. Customers like the battery’s size, with one mentioning it fits perfectly and another noting it accommodates in a larger ammo box.

This is to ensure the battery is protected from overvoltage and that it’s charged to its maximum capacity. Sulfation is a buildup of lead sulfate crystals on lead-acid battery plates. It occurs whenever a battery is left without a full charge, which is the main reason lead-acid batteries lose performance and fail. Sulfation is responsible for longer charging times, shorter run times, and battery life. On average, a high-quality deep-cycle battery with a trolling motor can last between 3 and 5 years. If the battery discharges frequently or incorrectly, its lifespan will be shorter.

I can monitor my battery’s status in real-time and manage its discharge with ease.
