LiFePo4 Battery 100ah vs lead-acid batteries, which is the best boat battery

LiFePo4 Battery 100ah

In the Boat world, LiFePo4 Battery 100ah is becoming increasingly popular over lead-acid battery, and not just on larger sailboats and yachts. Many people are switching to lithium batteries to power their bass boats, houseboats and even kayaking fishers!

We found that LiFePo4 Battery 100ah has many advantages over lead-acid battery and more people choose them, such as the better performance and the longer service life. Their weight is a third as much as lead-acid batteries and their recharging is quick. We can see how this affects your choice of the best boat batteries for you and which choice is available.

Find the components you need

This may vary depending on the type of boat you use and how the battery is used. In some cases, you can replace your lead acid battery with a pluggable lithium battery, but in most cases, you’ll need to replace some other components as well.

Boat batteries are generally divided into three types and popular types: starter boat batteries, deep cycle boat batteries, and multi-purpose boat batteries.

Starter batteries vs Deep cycle boat batteries

The starter boat batteries are just like the normal starter batteries in the car. They provide transient power (start amplifiers) to start your Marine motor. Discharging them below 50% can damage them and shorten their life span.

Deep-cycle boat batteries can run out slowly over a long period. Its according to the kinds of deep cycle batteries you used, there will be no damage even if you repeatedly exhaust them to 70% or more of their capacity. Generally, this means a “deep cycle.” But the deep-cycle batteries have no starting current.

Starter batteries vs Deep cycle boat batteries

Generally, the multipurpose boat batteries are combined with most of the advantages of starter batteries and deep cycle batteries, and also their construction of the multipurpose batteries can start small boat motors, and also metering lights and power that does not use up an amount of electricity, etc.

The usage of the boat batteries

Usually, before you choose the best boat batteries, there are 3 types of boat power and battery systems needed to consider.

Single multipurpose boat battery pack

The simplest system is a single multi-purpose battery pack. Multipurpose battery systems are common in everyday vessels, such as speedboats or general recreation. Generally, the main goal of the batteries will be to start the motor, which might run lights and power your radio. The battery’s continuous power consumption is very low, and you usually don’t use up enough power to cause damage. However, accidentally leaving the lights on or the radio running for too long can damage the battery, leaving you stranded and unable to start the engine.

Separate start and house system boat battery pack

Generally, sailboats, houseboats, and catamarans also require different kinds of batteries. Such as the most boats or marines, usually need starter-up batteries to start their big motors.

The difference between fishing boats or the national boats, and the in boats require battery systems to power all the electronics and appliances you need for daily life. This need to include the fans, the lights, the possible inverters, and also the dc electrical power supplies. The special houseboat system battery pack will be no different from the battery system in an off-grid RV or house in a different way.

Separate starting and trawling motor batteries

Special fishing boats equipped with trawling motors require start-up batteries and deep cycle trawling boat batteries. Trying to power a trawler motor all day with starter batteries or multi-purpose batteries is not going to work. Not only will the battery drain quickly, but deep-cycle start or multi-purpose batteries can damage the battery. This can also get you bogged down, as your trawl motor may kill the starting battery.

What’s the important point while buying good boat batteries

Your application system can determine which boot battery you need, the starter batteries or the deep cycle battery systems, or you might need the multi-purpose batteries. Whatever your application, there are some points to remember when looking for any boat batteries.

Efficiency is crucial. The efficiency of the battery, thats you can discharge the batteries up to 70% or more of their capacity, and then charge it quickly but with no damaging it.

Reliability and service life are also essential considerations when choosing boat batteries. If you are not willing to be fishing miles offshore and unable to start the motor home because the battery is dead. Similarly, imagine taking your friends for a weekend on your sailboat and letting your battery system hiss on you. It’s not a wonderful vacation. Besides, batteries are costly. Have to do the replacement often due to they will short the service life or warranties will add up faster.

And last, but not least, the weight. Batteries will be heavier. This is starting to become an important consideration for boat and trawl battery systems, where you may need multiple batteries to provide the desired capacity.

Ultimately, if you want to look for the most efficient, less weight, or most reliable batteries you can afford. Let’s look at some of the options.

Type of deep cycle ship battery

Lead-acid deep cycle boat battery

There are two main types of Marine batteries for the deep lead-acid cycle: Flooded liquid lead-acid (FLA) and absorbent glass pad (AGM).

Generally, the flooded liquid lead-acid battery is the most basic kind of lead-acid battery and they need to include a solution of sulfuric acid in which lead plates are suspended. As well as you must constantly monitor them and regularly add water to the battery to keep them running.

Absorbent glass pad batteries are sometimes called sealed lead-acid batteries. As the name suggests, these batteries are sealed and do not require the maintenance of the FLA batteries. AGM batteries will have their lead plates, however, they will sit between electrolyte-saturated fiberglass plates.

Advantages

Generally, the 12V100Ah lead-acid battery is a very common and readily available item of deep cycle battery. They will have the cheapest upfront prices, which is attractive to people on a budget.

However, the lead-acid battery does not have any electronics in them, so it can provide several amperes. This is a reason to choose them for the starting batteries.

Disadvantages

Lead-acid batteries have several major disadvantages. The first is that they need additional maintenance than different deep-cycle batteries to confirm they continue to be in high operating condition. Whereas AGM batteries don’t need equivalent maintenance as FLA batteries, they value way more while not adding any extra capability.

Deep cycle lead-acid batteries must not discharge less than 50% of their capability. Doing therefore will harm them. In addition, because of the lead-acid batteries discharge, their voltage drops much. Combining these 2 factors implies that you sometimes only get around 0.5 of the rated capability from a 12V100AH lead-acid battery.

Whereas deep-cycle lead-acid batteries have a very cheap initial value, they even have the shortest generation, lasting only 2 to 5 years. owing to the lead plate, lead-acid batteries are significant, which isn’t ideal for yachting applications wherever weight is essential. Finally, FLA batteries are not sealed, therefore they must be installed upright to prevent acid leaks.

Lithium-ion deep cycle boat batteries

LiFePo4 Battery 100ah will use lithium salts instead of lead plates and sulfuric acid, to keep the energy. They are relatively fresh and still the high costly type of deep cycle batteries. Even if their high upfront costs will be usually justified by their numerous advantages, most of all for boating applications.

Advantages

You can drain lithium-ion deep-cycle boat batteries to 70% or additional of their capability while not damaging them. Also, with the right charging controller, they charge quicker than lead-acid batteries. This mixture can make LiFePo4 Battery 100ah more efficient than lead-acid batteries.

Lithium-ion batteries have a special integrated battery management system (BMS) that monitors battery health and eliminates the requirement for normal maintenance. BMS additionally optimizes the charge and discharge of the battery cells and is sure that the battery continuously operates among its safe vary. These properties will build lithium batteries 2 to 4 times longer than lead-acid batteries.

Lithium-ion deep-cycle batteries don’t contain the lead plates with high capacity and weigh regarding 0.5 the maximum amount of lead-acid batteries of the capability. As we tend to mentioned earlier, this can be an enormous advantage for boats wherever each pound counts. 

Disadvantages

The biggest disadvantage of lithium-ion boat batteries is their initial direct value. Even if you may typically find yourself saving cash within the long run they generally last a minimum of 5 times longer than typical lead-acid batteries. Another issue to think about is that the utmost electrical phenomenon output of lithium-ion batteries is way below that of lead-acid batteries. This suggests that lithium-ion batteries are not a perfect choice for starting batteries that need a high beginning current.

The best boat battery for your use

Which type of boat battery is best for you will be depended on your specific application. However, for any application that requires deep cycling, lithium-ion boat batteries will be your best bet. When you need the starter batteries, the lithium-ion boat batteries will not outperform the lead-acid batteries in matters of reliability, efficiency, weight, and whole costs.

Conclusions:

Whether you’re going for a fun day out at sea, cruising around the lake, trawling trophy fish, or staying on a houseboat, choosing the lifepo4 battery 100ah that’s best for your use is crucial. However, no battery can contact all of them. Even if knowing your application and the advantages of different choices, you can choose the suitable boat battery for you.
