Buying from the most competent 24V lifepo4 battery 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.

An excellent writer, when he isn’t fishing Joe is sharing his recommendations, hints & tips with the readers at OutdoorWorld Reviews. Cover the terminals in a thin layer of dielectric tune-up grease to prevent corrosion, but only once you’ve removed all traces of water. All review specifications include battery dimensions and its weight.

So your choice of battery is going to depend on what you can afford. If you want a battery that is durable and delivers excellent performance, AGM batteries would be the best choice. Lithium-ion batteries are lighter than both lead-acid and AGM batteries. They also charge more quickly and have a longer life than the two batteries.

Batteries are pretty heavy, ranging from pounds, and on a fishing vessel, chances are you’ll have at least two. On top of that, the size is smaller and more portable, allowing for use in almost any boat. The weight is 43.5 pounds, and the dimensions are 10×6.75×7.8 inches. Flooded wet-cell batteries are less expensive, but they don’t perform as well as the other choices. Wet cell batteries can spill acid, so they don’t stand up to vibration well and have to be mounted in a level position.

And the lead acid trolling motor battery costs much less but it weighs more with less energy density. Some large-capacity trolling motor batteries are so large that they are too big for use on kayaks. This lithium-ion battery from Battle Born weighs just 31lbs, making it much more suitable for kayak use, and yet, it still has 100 amp-hours capacity. Also, never mix two different types of trolling motor batteries.

And given that its price is reasonable, if you’re prepared to maintain this battery, it’s a very, very good choice for trolling motors. Chalk that up to 200 minutes of reserve capacity, a number that’s definitely at the high-end of battery performance. Rest assured, whether you run a 12-, 24-, or 36-volt trolling motor, the VMAX MR127 will provide the power you need, season after season. As mentioned above, the larger trolling motor battery group size usually has more capacity.

Boat Trolling Motor Battery Everything Explained

What many folks don’t know is that 36V controllers are made to work in 36V environments and give you way more leeway in one battery degrading your whole system. First, you have to understand in parallel or series systems, when one battery goes down, the whole thing is down. If, on the other hand, you want a light and high-performing battery that will last you many years, lithium is the way to go. I recommend you also read reviews and learn about other users’ experiences with customer support. It’s great if you know you can pick up your phone and get any advice you may need. In this case, your motor shouldn’t draw more than 60 Amps, preferably closer to 50 Amps.

You’re limited in how much power you get, taking away some potential of your boating accessories. A deep-cycle battery can run for an extended time and consume only a small amount of energy. The higher the amp hours (capacity of your battery), the longer your battery will perform. These include a longer lifespan, higher cycle life, and better resistance to vibration and shock. AGM batteries are also maintenance-free, meaning you won’t have to refill them like a Lead-Acid wet cell.

Best Electronics Dedicated Battery

The water levels are only necessary for non-sealed lead-acid wet cell batteries. When searching for a battery the bigger the AH (amp hours), the more run time you’ll have. Whether you’re a bass boat fisherman or a kayak fisherman, the size of the battery is essential.

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.

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.

Especially when compared to a more expensive battery, which has endless possibilities. When making your final buy, think about where you’ll be placing the battery and whether you’ll have to add or remove weight to your boat. With that said, you must be conscious about battery placement and weight. If you have two 50-pound batteries on a Jon Boat, plus you in the stern, the boat will run with the bow in the air. You’ll need to find a proper place for the batteries to act as a counter balance.

If you want to avoid disappointment, you want your lithium battery to come from a reputable source, with a warranty and support. 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.

Equipped with a 150A BMS, it delivers a 1920W high power output for larger appliances on your boat. Its fast-charging capability allows it to fully recharge in about 2 hours, making it perfect for long days on the water. Customers appreciate the battery’s compact size, noting it’s great for small boats and kayaks, with one customer mentioning it works well with their Minn Kota Endura C2 trolling motor.

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.

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.
