Tycorun lithium battery

Our batteries work with all 12V, 24V, and 36V trolling Motors and offer the greatest flexibility as a dual purpose battery for deep cycle and starting. Our lithium batteries hold above 13 volts for your trolling motor giving it the power it needs to keep running at its highest thrust throughout the entire day. In contrast lead batteries, their initial voltage starts at 12.8V and quickly go down to 11V in in strong current or winds. This causes your motor to run slower when you need power the most. Our batteries use LiFePO4 Lithium Iron Phosphate chemistry, a strong electrolyte capable storing an extraordinary amount of power.

When you start your motor a heavy load is placed on your battery. Voltage in lead acid and AGM batteries starts out low and can drop below 10V during cranking causing your motor to spin over slowly. Our lithium batteries hold a steady voltage above 13V giving your starter all the power it needs to start your engine noticeably faster and stronger. At the same time, ourRV lithium batteryis also made using this technology.

Thus, lithium marine batteries are normally more costly than batteries used for automobiles, which can entice some boat proprietors to buy an auto battery rather than a marine battery. Try not to settle on that helpless choice. A?12v lithium deep cycle?marine battery?will last more and be more dependable than an auto battery in a boat.

This buying is covering the different features you need to know before making a buying decision. Let’s know more about this.?

1. What is Marine Battery?

What is Marine Battery?

Different kinds of boats use batteries to perform some specific tasks and these batteries are designed in such a way that they contain electric plates with high weight density & very solid robust development so, that they can perform better when installed within the boats.

These batteries are constructed in such a way that they can stand firmly against different kinds of vibrations, jerks when the boat moves on to the water and any type of materiel hits with the battery due to bad movement of a boat.Similarly, our?deep-cycle mobility scooter battery?is also made with this structure, which can make our scooter run smoothly on the road, and the power and battery life can also be guaranteed.

Lithium marine batteries are the most often used batteries for boats because they are designed with the latest battery management system having greater lifecycle and better power ratio as compared to other auto batteries.

2. What are the Types of Marine Battery?

Basically, there are many different types of batteries that can be used in a boat but when you talk about Lithium marine batteries these are some of the following battery types that are used in boats.

? Starting Batteries for Marine

As most of the power batteries that we often use in our cars and other vehicles these batteries provide the powerful electric burst to start the engine of the car and this starting marine battery does the same to give a powerful electric burst to the boat engine.

You can not use the startup battery for other appliances that are installed in the boat because they are only used to start the boat engine and then charged quickly with the power of boat engine to store energy for later use.

? Deep Cycle Batteries for Marine

Most of the?deep cycle Lithium marine batteries?are often used to work as a powerhouse to operate different kinds of appliances like oven system in boats, refrigerators, audio & video system, trolling motors and other fishing appliances like fishfinder/locater or ground depth finder.

These batteries take some time during charging as compared to startup marine battery but they can be used for a longer time to run multiple appliances.

? Dual-Stand Batteries for Marine

As you know by the name these Lithium marine batteries are developed with the combination of deep cycle and starting marine battery to work as a double standard marine battery.

This marine battery type can work as a starting battery for your boat engine as well as deep cycle to run different appliances. When there is less space on the boat to install 2 batteries than people who use this dual-standard marine battery but when you talk about performance rate and efficiency is better to use two single batteries.

3. Which Category of 12v Marine Battery one can use?

Which Category of 12v Marine Battery one can use?

If you want to use a 12v lithium marine battery then some of the categories fall into this type of requirement.

These 12v batteries will give you more lasting time, safe to use and it also has a long lifecycle as compared to AGM and lead-acid battery types.

4. How do you charge a marine battery?

If there is a starting marine battery present in your boat which is only used to start the engine or to provide an electrical spark then there is no special way to charge the battery as it will be charged automatically by the engine.

And if there is a deep cycle marine battery that operates the multiple appliances of your boat then you have to charge it with the help of a specific charger as it can not be charged with the engine power.

Any type of standard charger or a special charger can be used to charge the battery according to the charger and battery specifications.

5. How long Marine Battery Lasts when it is fully charged?

How long Marine Battery Lasts when it is fully charged?

The long-lasting of your battery depends upon its usage like what type of appliances you are operating with the help of this battery.

If there is a single application running with the battery power then it will remain more than 4 to 5 hours but if multiple appliances are operating through the battery then it may remain up to 3 hours or less.

Use the maintenance charger to charge the battery up to the maximum level and it will help your battery to remain in quality shape with better lifespan.

A normal marine battery total lifespan is about 3 years but if you keep your battery in good condition under good maintenance then it may remain longer than 3 years.

6. How to Choose a Marine Battery?

First and for most you must know the purpose of your battery like is it going to be a startup battery or a battery that can run your appliances that are present inside the boat.

In this way, it will be better for you to choose the battery for your marine system.?Deep cycle batteries?are normally used to operate multiple appliances within the boat system.

Make sure to understand the required power that your appliances want then choose the battery according to these specifications and always select the battery with a better performance rate, greater durability values, safe construction, and greater power density.

And 12v batteries are best if you want to take your marine system up to the next level because these batteries have all the specifications that a marine system requires.

7. When should you replace your Marine Battery?

When should you replace your Marine Battery?

As I explained earlier the lifespan of a normal marine battery is about 3 to 4 years and after that, you may have difficulty to work with them.

When you see your battery is not giving you the lasting time as it was giving you before or it is causing you trouble in terms of charging and discharging then try to replace it.

If your battery required more maintenance then its work rate then try to replace it with the newer one as the battery may have dead cells or connectivity problems.

Most of the Lithium marine batteries when charged up to a maximum level they discharge very quickly at that moment you must know that your battery is maybe at a dying level or its lifespan is about to be over.

The replacement of a battery is made according to its performance level and if it cause you trouble again and again.

8. What Size Battery can be used in the Marine Battery System?

Size of a battery to use in the marine system depends on the space or area that you have to install the battery the size of a battery depends on your area size.

If you have much space to easily adjust the large size battery then you can use a larger size battery for the marine system. There are many different sizes of Lithium marine batteries that are present in the market.

If you have less space to install or to mount the battery within the marine system then you can use a 24-meter marine battery as it is the smallest size battery that can be used in the marine system.

27 and 31 marine battery sizes often come in middle size batteries like these batteries have medium size and can be adjusted easily in a space or area of 30 to 32 meters.

Larger size batteries that we most often hear are came as 4D and 8D as these batteries are greater in size and they will require more space to get installed within your marine system.?

These are some of the batteries with different physical size appearance according to their shape, design, and construction. The current capacity of these batteries has no connection with their size as all of these different size batteries have their own specifications.

If you want to choose the best battery size for your marine system then try to know these points like cranking Amps that your applications or your system has required, what is the Amperage level that your system requires, what type of battery you want for your system, & parallel cells connection that what are the number of these cells connected in a parallel way.

In this way, you will have the best battery size for your marine system.
