How to choose the appropriate lithium marine battery?
With a lithium marine battery, you can spend more time on the water. There are numerous reasons why more and more sailors are switching to lithium marine batteries.
Prepare yourself for a long, wonderful day on the lake by getting packed. then discover the battery is dead. Someone failed to check the battery the previous evening. A dead battery means nothing if you have leisure or athletic activities scheduled for the day.
The good news is that lithium marine battery not only keep their charge for a longer period of time, but if you select Maxworld, they also come with Bluetooth capabilities. You can quickly check the status of your batteries with a few touches on your smartphone. It is that simple. Additionally, each of our batteries includes a built-in BMS that prevents overcharging.

Cold weather protection built-in
The built-in cold weather protection of Maxworld lithium marine battery prevents them from taking a charge when the outside temperature is below -4C or 24F in our instance. Some differences in part tolerances
Our Maxworld lithium marine battery enables a charger once the battery has warmed up by warming it up. Deep-cycle marine battery sometimes plays an important role.
Types of Lithium Marine Battery and Their Purpose
Most bass boats need one of two standard 12-volt battery types. One form of battery is a cranking or starting battery. It kicks off the main engine. The deep-cycle marine battery is the alternative type. The trolling motor and other accessories are powered by it. Some batteries do both functions (to some extent anyway).
Cranking Lithium Marine Battery
Most bass boats need one of two standard 12-volt battery types. The primary engine is started using a cranking or starting battery. The trolling motor and various devices are powered by deep-cycle marine batteries. Some batteries, at least to some extent, perform both.
Deep cycle Lithium Marine Battery
In contrast to cranking batteries, deep-cycle batteries are made to release power gradually. Over the course of their lives, they can be repeatedly discharged and recharged. While both are crucial, deep-cycle batteries are what you rely on the most for power and navigation. The trolling motor and other battery-operated devices on your boat are powered by these batteries. (Like your GPS, fish finder, and music system.)Lithium marine batteries can make the ship’s endurance longer.
Dual Purpose Lithium Marine Battery
Some boats need a dual-purpose lithium marine battery since they don’t have enough space for more than one battery. Despite the fact that dual-purpose batteries are commercially available, many boaters avoid using them. because a cranking battery has greater power. Additionally, they don’t possess a deep-cycle battery’s longevity. The majority of pros instead choose two different batteries. So you can add a lithium marine battery to your ship.
The 4 Boat Battery Technology Types
You can select from four distinct technologies. There are several types of batteries: lead-acid, gel, AGM (Absorbed Glass Mat), and lithium. Here are each’s benefits and drawbacks:
LEAD-ACID BATTERY
These batteries may be recharged numerous times and are inexpensive in the short run. They must be continually maintained to prevent issues because they also break easily. Every few weeks, you should check the water level and top it off to avoid harming your batteries. Additionally, leaking raises several safety concerns and has the potential to be disastrous to maritime environments.
GEL BATTERY
Because they don’t need to be recharged very frequently and can be stored for a long time without losing power, gel batteries are quite popular. Their disadvantage is that they are more expensive than other batteries with the same RC and MCA. A gel battery’s charging process can be a pain. You must be there to turn off the battery charger after the charging cycle is finished because it can take a while to complete. Failure to do so may result in permanent damage, necessitating the purchase of a new battery and throwing a lot of money away. Some ships also use diehard marine batteries.
Something you should know about EV LiFePo4 Battery
AGM BATTERY
These batteries seldom ever leak and don’t need a lot of maintenance. However, the initial investment is high, and if they do require repair due to excessive use, it’s challenging to access the inside parts. Most likely, you’ll merely need to get a brand-new battery. They also need more battery charges because their maximum capacity of discharge is only 50%, compared to 100% for a Maxworld lithium battery.
LITHIUM BATTERY
Like comparing an iPhone to a flip phone, comparing lithium batteries to other types is unfair. Both solutions are functional, but one plainly has a better design, function, and reliability. Although lithium batteries are more expensive, they are also more durable, weigh less, require no maintenance, and are not harmful to the environment. Moreover, what about Maxworld batteries? Currently, these are the only group24 lithium deep cycle battery on the market that support Bluetooth. This eliminates all uncertainty and concern. Unlike other batteries, our lithium batteries will let you know exactly how much charge is remaining.
The Maxworld Lithium Marine Battery Advantage
Professional anglers and boaters have begun adopting these batteries in greater numbers. because of their lengthy lifespan, reliable output, and capacity to hold a charge. Lithium is a fantastic choice whether you’re a professional or a weekend warrior. This is why.
Consistent Output
Once the battery has used about half of its capacity, the majority of commercial batteries will no longer provide as much amperage. As a result, even though you could still have 50% of your battery left, some of your accessories can cease working because the amperage isn’t as strong.
Lithium marine batteries, in contrast, continue to produce the same amount of amperage even when their battery life has dropped below 50%. In addition, lithium batteries can run completely down before needing to be recharged.
Maintain Charge
If you recall from the previous part, gel batteries are frequently purchased due to their capacity to hold a charge even while not in use. And Maxworld lithium marine batteries are capable of doing the same.
Lithium marine batteries may hold their charge for years, in contrast to many other types of batteries. Even if they are not used or kept charged and are placed in a storage shed.
Lightweight
When they need maintenance, most batteries add weight to your boat and are challenging to transfer. Since the 8d lithium marine battery is small and light, it can fit on practically any boat and perform its function without adding weight to them. Gas costs will be lower, and your navigational skills will improve.
Status Monitoring
In addition to charging significantly more quickly than lead-acid batteries, marine lithium batteries also provide Bluetooth functionality. You can see exactly how much charge is left in the battery and how long the charging cycle will take, eliminating the need to guess whether or not the battery needs to be recharged. All with just a few phone touches using the Maxworld iOS or Android app.
Long Lasting
There is usually a lot of truth to the adage “you get what you pay for,” which we have all heard. You will pay more upfront for a Maxworld lithium marine battery, but you will end up saving a lot of money over time. How? Read on.
Typically, a lithium marine battery lasts 2-4 times longer than a lead-acid battery (and up to 10x longer). Typically, a lead-acid battery can be recharged 300–400 times. It will likely last you around a year if you use it every day.
Our Maxworld lithium marine battery, in contrast, has a 5000-cycle life rating, which means it can be recharged 5000 times. If you use it every day, that’s almost 14 years. Therefore, even though the lithium marine battery is more expensive initially, you will end up spending significantly less money overall.
Environmentally Friendly
Leakage from lead-acid batteries is a well-known problem. If you don’t take care of them properly, they could spill battery acid onto your boat and into the sea. Our lithium batteries have no harmful leaks. They can even be recycled.
Additionally, since our Maxworld lithium marine batteries don’t contain any harmful chemicals, they don’t need any kind of ventilation. As a result, you can keep them wherever including inside.

TYPICAL LITHIUM MARINE BATTERY SETUPS
Three 12V 50Ah batteries for the trolling motor and one 12V 125Ah battery for your engine starter and other devices like a fish finder make up the most typical battery configuration for bass boats with a 36V trolling motor.
Then why not replace your three 12V trolling motor batteries with a single 36V 50Ah battery if simplicity is what you’re after? There will be fewer cables to connect and connecting points to be concerned about.
Both options include advantages and disadvantages, thus neither is superior to the other. Finding what works best for you is what matters most in the end! Here is a detailed comparison of one 36V battery and three 12V batteries.
Fewer batteries are sufficient for smaller bass boats: You could use two 12V 100Ah batteries for the trolling motor and one 12V 125Ah battery for the engine starter and other onboard devices if you were using a 24-volt trolling motor.

Let’s examine the advantages of marine lithium batteries and respond to some often asked questions.
Why Boaters Are Choosing Lithium Marine Battery?
In comparison to lead-acid batteries, lithium-ion marine batteries are more effective, lighter, and can last up to ten times longer. A great option for boating applications, lithium batteries have all of these advantages.
Size & Weight Reduction
There is a weight restriction on every boat, therefore it goes without saying that you should try to keep your load as light as possible. Lithium batteries often weigh half as much as lead-acid batteries of the same capacity.
A Maxworld 100 Ah lithium battery, for instance, weighs roughly 31 pounds. Depending on the battery type, a 100 Ah lead-acid battery typically weighs between 60 and 80 pounds.
Increased Number of Charge-Discharge Cycles
Marine deep-cycle lead-acid batteries typically have a lifespan of 500 to 1,000 charge-discharge cycles. As an alternative, a lithium marine battery’s lifecycle typically ranges from 3,000 to 5,000 cycles.
A lead-acid battery’s longevity is also influenced by how well you take care of it. To maximize their performance and durability, lithium-ion batteries require essentially minimal maintenance.
Increased Power Storage
A lead-acid battery’s life is shortened and damaged when it is discharged below 50% of its capacity. On the other hand, the majority of lithium battery producers rate their batteries to permit a depth of discharge of 80%. The batteries we produce can be fully discharged without suffering any harm.
One of the major advantages of lithium batteries is their improved capacity for power storage. You typically get roughly twice as many batteries, so you could only need half of them. As there are half as many batteries, the weight is reduced by a factor of approximately four when compared to lead-acid batteries.
Cheaper Long-Term
A lithium marine battery is substantially more expensive upfront than a lead-acid battery. But lithium batteries frequently have a lifespan that is at least five times longer than that of lead-acid batteries.
In the long run, lithium-ion marine batteries are less expensive due to their higher efficiency and longer lifespan. Additionally, keep in mind that you could only require half as many lithium batteries as lead-acid batteries.
Is It Easy to Make the Switch to a Lithium Marine Battery?
Many lithium batteries are drop-in replacements, which means they are made to fit in your battery bank just like a regular lead-acid battery would. It’s not always plug-and-play, though. To finish your installation, you might require more parts.
You might need to upgrade your inverter and battery charger to get the best performance, depending on your use and application. Furthermore, lithium batteries don’t exhibit any telltale indicators that they’re ready to fail, so you might also need to include a battery monitor.
The majority of these adjustments are rather simple, but electrical system mistakes can be risky. Please contact a specialist if you are unsure if switching to lithium marine batteries on your own will be successful.
How Long Do Lithium-Ion Marine Batteries Last?
3,000–5,000 charge cycles is the normal lifespan of lithium marine batteries. Lithium batteries typically last 10 years or more as a result.
In fact, our lithium batteries come with 5-year guarantees from Maxworld Energy. In contrast, the majority of lead-acid battery manufacturers provide one to five-year guarantees.
Are Lithium Batteries Safe on Boats?
Lithium batteries are secure for use in boats and maritime applications. Since lithium batteries are sealed, even a small amount of water splashing on them won’t hurt them.
In addition, inbuilt battery management systems are present in the majority of lithium batteries (BMS). To avoid damage or thermal runaway, the BMS will shut down the battery when it detects harmful conditions.
How Expensive Are Lithium Marine Batteries?
A lithium marine battery with a 100 Ah capacity typically costs around $1,000. Compared to existing lead-acid alternatives, the upfront cost is much higher, but the overall long-term cost is cheaper.
Is Upgrading Your Marine Battery to Lithium Worth It?
Lithium-ion batteries are far more expensive than lead-acid batteries, as we have already stated. However, you gain the advantages of a large weight reduction, improved efficiency, better safety, and a significantly longer lifespan in exchange for the additional cost.
Lithium marine batteries are not only ultimately more cost-effective when all is said and done, but they are also totally worth the investment.
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 sulfate 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.
