What is a good Marine lithium battery?

Marine batteries are specially designed for use on ships. They are usually sturdy structures that can withstand any vibrations and shocks that may occur on a motorboat.

In addition, the power of different ships also varies. Moreover, the electronic devices used on the ship are also different, so batteries of different capacities are also required. When powering devices such as GPS or fish finders, choose a Marine battery of the right size so as not to damage your valuable equipment or run out of power.

Because the space in the battery compartments of different ships varies. Generally, the size of the battery must be designed based on the size of the ship's battery compartment. Having been engaged in the field of battery customization services (battery ODM and OEM) for many years. EverExceed can fully customize battery sizes according to customer requirements.

What is a lithium battery?

Lithium iron phosphate battery is a relatively new and rapidly developing battery technology that generates electricity through a process different from that of traditional lead-acid batteries. In those old-fashioned batteries, electricity was produced through the reaction of lead plates in sulfuric acid solution.

On the contrary, when lithium batteries generate energy, lithium ions move from the negatively charged anode to the positively charged cathode through the electrolyte solution. This may seem like a subtle distinction, but it is of great significance when it comes to the huge advantages of lithium batteries over traditional battery technologies.

Types of Marine batteries

There are three types of Marine batteries:

Marine starting batteries provide rapid and powerful energy bursts in a short period of time. We always use it to start the engine and quickly charge it through the engine alternator. Starting batteries should not be used for traction motors or to power equipment.

The design of Marine deep-cycle batteries is to discharge slowly over a long period of time and withstand hundreds of charge and discharge cycles. Deep cycle batteries are the right choice for powering electric drag cable motors and other battery-powered accessories such as audio systems, winches, depth sounders, fish locators and applications. Generally, we should not mix deep-cycle batteries and starting batteries.

Marine dual-purpose batteries combine the performance of starting batteries and deep-cycle batteries. They are a good choice for small batteries when there is no space to accommodate both. Although they can perform the tasks of starting batteries and deep-cycle batteries, their efficiency is not as good as that of individual batteries.

The advantages of LiFePO4 lithium ship batteries

Lightweight and compact

The electrodes (lithium and carbon) commonly used in lithium-ion batteries are themselves very light. Make them smaller and lighter than old-fashioned batteries such as lead-acid batteries. In contrast, a typical 100Ah (ampere-hours) lithium-ion battery weighs the same as a 40Ah lead-acid battery (approximately 10-12kg). But its capacity is more than twice that of it.

100% depth of discharge (DOD)

Maximize your energy potential and achieve 100% discharge depth. This means you can use 100% of the battery capacity to meet your specific needs. When the power is exhausted, lead-acid/AGM batteries will gradually reduce their power and performance.

High energy density

Lithium has the ability to release and store a large amount of energy. Enable lithium-ion batteries to package high energy capacity in a small size. This means that lithium-ion batteries of the same weight can last much longer between charges than other rechargeable batteries. At the same time, it still maintains its high-level performance.

Low maintenance cost

The old types of rechargeable batteries, such as nickel-cadmium batteries or nickel-metal-hydride batteries, have what is called the "memory effect" or "inert battery effect". If partial discharge is repeatedly carried out before charging, the battery will eventually only be partially powered until the voltage drops. The energy used during discharge. To avoid this situation, we need to fully discharge nickel-cadmium batteries and nickel-metal-hydride batteries and charge them regularly for maintenance.

Lithium-ion batteries have no memory effect, which means they always run out of the last bit of power. Whether you are using 100% or 25% capacity, you can charge it without the need for cumbersome maintenance!

How to choose the right Marine battery?

High-quality lithium iron phosphate chemical (also known as LiFePO4 or LFP batteries) is the best choice for Marine batteries. EverExceed always provides the safest and most reliable batteries for all Marine applications.
