What many folks don’t know is that 24V lifepo4 battery 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.
The upside is that flooded motors are designed to be used with trolling motors and prove to be an economical option. The Redodo 12V 140Ah Bluetooth Group 31 lithium battery is one of the best trolling motor battery choices available, designed for trolling motors with thrust ratings between lbs. It provides 40% more capacity than a standard 100Ah battery without taking up extra space, ensuring extended trolling motor runtime.
The amperage per hour rating determines how long your trolling motor battery will run before it needs recharging. In the main, a higher amp-hour rating is better as it means you’ll be able to go further per charge. Their blue top range is especially good for marine usage and trolling motors.
How Long Does A Battery Take To Recharge?
Some EFBs are used in start-stop cars because they have a similar power profile to AGM batteries. Often times you can find this on the battery or the manual if you still have it. A quick good search should also reveal a better way to find it on your specific battery. The only negative thing that is said about this battery is that it’s a little bigger and more difficult to install.
As one of the best 12V 100Ah lithium battery for trolling motor, the battery is perfect for trolling motors with thrust ratings between lbs. It provides up to double the runtime of traditional AGM batteries, while weighing 1/3 less (only 22.16 lbs total), improving boat speed and efficiency. The best marine battery for a trolling motor, according to our recommendation, is the 12volt deep cycle marine battery. It needs to have at least a 110 amp hour rating, and ideally, it should be of 27 sizes.
You can’t usually ship wet cell batteries, so you’ll have to pick these up in-store. This VMAX battery is rugged and capable of withstanding pretty extreme conditions. Reviewers note that the battery holds a good charge and lasts long enough to stay on the water all day.
With 120 amp-hours to call on, you won’t even need to charge this battery after every trip. This reliable battery is a big unit, but it’s a very reliable option if you’ve got the space. The one drawback of having all this power is the battery is on the bigger side. It weighs a whopping 68 lbs and measures 7” x 9” x 12”, so it’s not going to fit in some smaller boats and will add a good bit of weight to your overall capacity.
A single battery with a powerful current of 50A maximum can make a motor working for 2 hours in a row. In general, if you are not sure about a lithium battery choice, we can recommend two more things to do besides consulting a motor producer. The first thing you should know is that the majority of trolling motor producers suggest buying LiFePO4 batteries. It means that Ferrum (iron) stands as a supporting element in a battery.
If you need two, always ensure they are the same type, i.e. two AGM batteries, two wet cell batteries, or two lithium-ion batteries. The size and weight of a trolling motor battery may impact the overall performance of the battery so make sure that it isn’t too heavy for your boat. When the weight capacity is reached in your boat the battery will drain much quicker, so look for lighter-weight batteries if you’re reaching maximum capacity. This alone makes it one of the top trolling motor batteries for smaller boats and kayaks, where one needs to closely manage the weight capacity. Its relatively compact dimensions (12″ x 6.7″ x 8.2″) are also perfect for applications where space is at a premium.
Best Trolling Battery For Larger Vessels
The Power Series AGM is their top-of-the-line Group 27 deep cycle battery. With improved efficiency and storage, this battery is rated to fish all day and take a beating. The AGM has a higher cold cranking rating and longer reserve time than lower-priced models. Lithium batteries weigh 60% less than equivalent lead-acid models—a 100Ah lithium battery averages 26 lbs vs. 65 lbs for AGM. Reduced weight improves boat stability, fuel efficiency, and payload capacity.
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.
Goldenmate is offering our readers a discount on their batteries as well. Impulse Lithium also offers a full, 10-year (non-prorated) warranty on their batteries. Read our full review on Impulse Lithium 12.8V and 36.4V batteries. They are expensive, but when you consider their much longer lifespan, the cost is comparable to lead-acid batteries, which need to be replaced more often. A BMS will also look after individual battery cells to make sure they are balanced and have the same voltage. However, there are many types of lithium-ion batteries, and in this article, we discuss only LiFePo4 (LFP) batteries, which are the easiest and safest to use.
This probably isn’t important if you charge your trolling motor battery overnight. However, fast charging brings about the possibility of recharging your batteries during the day or using a powerful outboard alternator or generator to top up your lithium battery. On the other hand, dual-purpose marine batteries give you the best of both worlds. With this battery type, you’re receiving cold-cranking amps and deep cycle power. SLA wet cell batteries have been around longer, which makes it a cheaper option. However, AGM batteries have better qualities, making the extra couple of bucks worth it.
Today’s batteries are stronger, more bulletproof, and in some cases, costlier, so make sure that you buy the correct option or options for your boating choice. Across the board, the best trolling motor batteries are likely to last at least all day on a charge, and not leave you stranded or weakened after hundreds of charge cycles. There seems to be as much misinformation out there as correct information and too many people trying to make lithium power work like lead acid batteries work.
