    How To Charge A Lithium Marine Battery

    When Marine lithium batteries are compared with lead-acid batteries, lithium batteries can be charged at a higher current and more efficiently. That means they can charge more quickly. Lithium-ion batteries have other advantages: they do not need to be recharged if they are partially discharged. Unlike lead-acid batteries, lead-acid batteries sulphate when partially charged, which greatly reduces performance and life.

    We recommend using multiple chargers so that each 12V battery can be charged separately to ensure they are balanced and fully charged. Ideally, use a charger with a lithium charging profile, but most AGM charging profiles will work fine.

    LiFePO4 Marine batteries can also be charged using most alternators. Depending on the quality of the alternator, it should be used with LiFePO4 batteries. A low-quality AC generator with poor voltage regulation will cause the BMS to disconnect the LiFePO4 battery. If the BMS disconnects the battery, the alternator may be damaged. To protect your LiFePO4 battery and alternator, be sure to use a compatible high quality alternator or install a voltage regulator.

    How To Choose The Correct Battery For A 24v Or 36v Trolling Motor

    Tournament Lithium 36V 100Ah Batteries

    LiFePO4 batteries have many advantages over traditional Lead Acid batteries. Longer operating times, weight savings and many more years of operation are just to name a few. All Amped Outdoors LiFePO4 batteries listed below have a built in BMS which will protect your battery from overcharging, discharging too low, high temp cutoff, short circuit, and has built in cell balancing technology. Make sure to check out the bottom on this page to see the graphed out power draw of a 36V system when we put it to the test!

    Sealed Lead Acid “Flooded” batteries can be up to 50% efficient and AGM can be up to 80%. This means you can expect to get 50-80% of the rated capacity. Our LiFePO4 batteries will give you 100%+ the rated capacity when new out of box.

    Today we are finding new motors with brushless technology drawing less power. Garmin and Lowrance will typically draw less than traditional brushed motors.

    Here is a helpful comparison for choosing the right battery for your setup!

    The Best Way To Store A Trolling Motor Battery

    Lithium Pros 40AMP/HR 36 volt Trolling Motor Batteries

    Proper storage of a trolling motor battery can extend its lifecycle. So here are some helpful tips on how to properly store one:

    • Before you store a trolling motor battery, always make sure you have charged it. If you store it without charging it, there is going to be a sulphate build-up which can cause corrosion. As a result, your battery is not going to hold much charge. Also if the battery is corroded, its life reduces significantly.
    • When a battery is stored in a hot environment, it is going to expand pushing out energy more quickly. So its discharge rate is going to be high and it may also lose its electrolyte. If you store in a cold environment, this is going to result in a low discharge rate. So the battery is forced to work harder straining the battery and as a result, reducing its lifespan. So store your battery in an environment where temperatures are not too low or high to keep in good condition and to extend its lifecycle.
    • When you store your battery, dont neglect it. Just because you are not using it doesnt mean that you should not clean it. Make sure to remove it occasionally for a good clean and ensure that it is fully charged.

    Advantages And Disadvantages Of Lithium Boat Batteries

    The key advantages of lithium batteries are as follows:

    • Longer run time
    • Longer battery lifespan
    • Shorter charging time

    The first two of these benefits are the most important ones, and are the reason why many professional anglers have switched from using lead acid batteries to lithium boat batteries. When youre fishing at a whole day tournament, its critical not to run out of battery power prematurely.

    The shorter charging time is also worth mentioning. While a lead acid battery often requires 8 to 10 hours for complete charging, this time is reduced to 2 to 6 hours for a lithium battery. That means you dont need to leave it on a charger overnight, but can get it ready for use again in very little time.

    The main disadvantage of lithium boat batteries is their relatively steep price: they cost about 3 times as much as standard lead acid boat batteries. However, when you factor in their long lifespan, you actually end up saving money on lithium batteries in the long run.

    How To Choose A Lithium Battery For A Trolling Motor

    If youre ready to get a lithium boat battery for your trolling motor, its best to choose one that is specifically designed for use with trolling motors, to make sure youre getting a compatible voltage. Also, choose a lithium battery with sufficient capacity to keep your trolling motor running the whole day.

    For a 12 volt trolling motor, the amp hour capacity of the battery should be equal to or greater than the pounds of thrust of the trolling motor, as shown below:

    • 20 to 55 lb motor thrust: 50Ah battery capacity
    • 70 to 112 lb motor thrust: 100Ah battery capacity

    When in doubt, get a battery with at least 100Ah, since that is usually enough to last a whole day with a 12 volt motor, unless youre mostly planning to spend only a few hours on the water at any one time.

    For 24 or 36 volt trolling motors, its best to get a single 24 or 36 volt lithium battery, since that reduces total battery weight, and also costs less than getting several 12 volt batteries to set them up in a series.

    The main exception to this is if you have a dual voltage trolling motor, such as the Garmin Force or Lowrance Ghost, which can operate with either 24 or 36 volts.

    The nice thing about these trolling motors is that you can change their thrust by changing the voltage of the battery system, in which case its great to have three 12 volt batteries that you can set up as either a 24 or 36 volt system.

    V 50ah Lightweight Lithium Batteries

    These small lithium batteries are great for kayaks, canoes, and inflatables.

    Although there are smaller and lighter batteries available with less than 50Ah capacity, they are not always suitable for a trolling motor because of the maximum current a BMS can deliver. Make sure to check the amp draw of your trolling motor.

    Do Lithium Marine Batteries Need A Special Charger

    Yes, you do need a special charger for lithium marine batteries. In general, you tend to need a special charger for any type of marine battery due to its unique design. But, lithium marine batteries need a special charger because they require charging in series with a multi-bank charger.

    A multi-bank charger is a type of charger that allows all the batteries in the chain to charge simultaneously. While these batteries charge at the same time, they are completely independent of one another, so the batteries charge on their own.

    You can use a regular battery charger to charge your lithium batteries, but this isnt ideal. If you have to do this, it is very important that you set the voltage on the charger to the absolute max. This allows your lithium batteries to charge to the best of their ability.

    What Do You Have To Do

    How Long Do Lithium Trolling Motor Batteries Last

    Run time testing has shown that lithium batteries tend to last 30% to 100% longer than lead acid batteries with comparable amp hour rating. For example, tests by Flux Power showed that their lithium battery has a run time that is 45% longer than a similarly rated lead acid battery.

    The reason why lithium batteries last longer with the same amount of charge is because their voltage output remains constant until they are completely discharged, while the output voltage of lead acid batteries rapidly declines during discharge, and falls below the required threshold long before they are empty.

    In other words, a lithium battery can keep on running your trolling motor until it is 100% depleted, while a lead acid battery stops being able to do so before it reaches even 70% depletion.

    Its also worth noting that because of this, the amount of runtime that you get for your trolling motor per pound of battery weight is much higher for lithium marine batteries, compared to that of lead acid marine batteries.

    Finally, lithium batteries also have a longer battery lifespan, as they degrade less during the charge/discharge cycles. This usually translates into a 2 to 3 years longer lifespan, which is important to keep in mind when deciding whether their higher price is justified.
