Are lithium batteries suitable for your trolling motors? How can you get the best lithium trolling motor battery for your money?This guide will answer all of the above and related questions to help you choose the most suitable trolling motor battery.
1.What are the types of trolling motor batteries?Trolling motor batteries are like your standard battery. However, they are for trolling motors. Generally, your boat starting batteries function to start the ignition of your boat engine. And marine battery provide power to run the boat and every other thing connected to your boat. Trolling motor batteries provide power to keep the boat going for hours, especially when slow trolling around fishing areas.The three most widely used battery options for trolling motors include lithium-ion batteries, sealed AGM batteries, and Flooded lead acid.
2.What type of battery do I need for my trolling motor?When it’s time for you to go on that fishing adventure, the last thing you’ll want to deal with is your battery dying on you. Although your trolling motor battery is specially built to provide continuous power to keep your boat motor going, it may not deliver steady power as long as you wish. For a long time, boating and fishing enthusiasts have relied on different trolling motor batteries, including AGM and lead-acid batteries. However, none of these options is yet to fully meet the reliability and efficiency that many fishing enthusiasts need. For these requirements, only the stronger lithium trolling motor battery provides the best functionality.
3.What is a lithium trolling motor battery?Boats generally need batteries for starting the engine and keeping it running. While some batteries work to start the boat, others are specifically designed to perform other functions, such as running the trolling motor. A lithium trolling motor battery is a trolling motor battery made of lithium iron phosphate (LiFePO4). This deep-cycle battery (mostly 12 volts) provides relatively low but constant power to trolling motors.
4.Are lithium batteries recommended for trolling motors?
As an angler or fisherman, your time on the water means a lot to you. You would do something to ensure that you utilize your moments. Your boat will always ask you for reliable and efficient trolling motor batteries. A reliable and efficient trolling motor battery means that you can recharge the battery in a much shorter period and still get to use your trolling machine for a long time. If you’re looking to make the best out of your boating or fishing exploit, you don’t necessarily need to buy a new trolling motor. A simple switch of your trolling motor batteries will be a better choice. We recommend switching to lithium-ion batteries if you want a longer-lasting battery with a quick recharge capacity.In the next paragraph of the article, we will explain why people recommend lithium trolling motor batteries more than other lithium ion battery types.
5.What are the advantages of lithium trolling motor batteries compared to other batteries?Lithium trolling motor batteries carries heavy advantages over their alternatives, including Sealed AGM batteries, Gel batteries, and Wet lead-acid batteries. Although lithium battery’s longer cycle life plays a huge role in making it the number one battery option for trolling motors, other advantages such as its high energy density, maintenance free, short charging time, and lesser weight make it stand out.
① Longer run timeThe longer run time of lithium batteries is one of the reasons why it remains thebest trolling motor battery choice for anglers. A lithium battery can offer you more run time on a single charge than any other batteries of the same capacity. While other batteries allow you to use a certain percentage of their amp-hour capacity before the discharge ends, lithium batteries allow you use up the amp-hour capacity before it stops providing power to your trolling motors. When you’re on a fishing tournament that requires staying long hours on the water, the last thing you’ll wish to happen is to run out of battery power early. The lithium trolling motor battery’s constant voltage at discharge makes its run time twice than that of other alternatives.
② Long cycle lifeThe long-life span of lithium trolling motor batteries is another point worth considering. Traditional trolling motor battery options usually have only a few hundred cycle times. During all these charge and discharge cycles, it becomes hard to get them fully charged to their optimum capacity. That is, their DOD dropped very quickly. As time proceeds, they start getting weak, and the voltage drops. In no time, the battery will fail to power your trolling motor. All batteries are not evergreen, they can power your trolling motors for more years than other trolling motor batteries. This true deep-cycle battery hardly drops its voltage at discharge. This gives it more years in your trolling motor than other alternatives.
③ Short charging timeWhile other trolling motor batteries like the lead-acid battery require up to 10 hours (8 to 10 hours) to reach a full charge, lithium batteries require about half of that time (2 to 5 hours) to get to full charge. With a lithium trolling motor battery, you don’t have to worry about trying to charge all night ahead of a boating adventure.
④ Less weightThe total weight on a boat is always of great importance to boaters. It affects the boat’s handling and performance. Typically, lithium batteries weigh about half or third of other conventional deep-cycle batteries. While a traditional marine battery like a lead-acid battery weighs about 70 pounds, lithium batteries weigh 20 pounds. As your trolling motor voltage may cause you to get up to three to four batteries, opting for lithium trolling motor batteries will save you over 150 pounds of weight.
⑤ Increased efficiencyWith the lesser weight of the battery, longer run time, and long shelf life on the side of lithium batteries, you’d be getting a more efficient system with lithium batteries. Lithium batteries are a more efficient option for your trolling motor.
⑥ Easy maintenanceLithium trolling motor batteries are easy to maintain, thanks to their built-in battery management system. This internal management technology controls the battery’s performance, charge rate, and temperature. It works round the clock to ensure safety and smooth power generation. In a traditional lead-acid battery, improper charging and temperature fluctuation can prove fatal to the battery system as they lack the battery management system to control this situation.
⑦ Long warrantyFinally, lithium trolling motor batteries come with a more extended warranty than other traditional deep-cycle marine battery. Even with the battery’s long-life span, lithium battery manufacturers also offer up to a 10-year warranty on their products. Other remarkable advantages of lithium trolling batteries over other existing trolling batteries include; 1.Low self discharge 2.Eco-friendly
6.How long does a lithium trolling motor battery last?Compared to other trolling battery options, run time testing has confirmed that lithium batteries can last longer. If you’re looking for a trolling motor battery that charges to full in the shortest possible time and still delivers power for a long time, the answer is never with the lead-acid or AGM batteries. Lithium trolling motor batteries last longer than others and still offer a decent amp hour rating. Your lithium battery will keep your trolling motor running until the battery is entirely empty. In contrast, your traditional batteries will stop the trolling motor from running as soon as it gets to 60 to 70% depletion. If you want to get the most out of your boating adventure, lithium batteries are sure to fire you up.
7.How to calculate the run time for a lithium trolling motor battery?The total run time of your lithium trolling motor depends on the entire power settings, which include the voltage of your motor and the max amp draw. To calculate the run time of your trolling motor battery, you have to determine,
- Yor motor voltage (volts)
- The max amp draw (amps)
- Capacities of your lithium battery in amp-hours (Ah)
