Choosing a battery for boats, Acoucou Battery Buying Guide

Choosing a battery for boats, Acoucou Battery Buying Guide

Marine batteries are an indispensable component of the boat's power system. Its selection and performance of marine batteries have a significant impact on the operation and safety of the boat's power system.

 

The selection of marine batteries needs to consider the following factors: electrical load, reliability, safety, weight, size, service life, etc. The power system and special requirements of the boats should be taken into account.

 

The selection of marine batteries needs to be determined based on the use and electrical load of the boat. Different types of boats have different power requirements. For example, large boats such as passenger boats, cargo boats, and oil tankers that require larger capacity batteries, and small boats can choose batteries with smaller capacities.

 

We also needs to consider reliability and safety. The power system of boats needs to ensure continuous operation, so the reliability of marine batteries is crucial. At the same time, the safety of batteries is also a factor that cannot be ignored. Marine batteries need to prevent problems such as short circuits, overcharging, and over-discharge to ensure safety. Besides, for extreme weather and harsh environments during navigation, batteries also need to have waterproof and explosion-proof characteristics.

In addition, the weight and size of marine batteries also need to be considered. The space of the boat is limited, so it is necessary to choose lightweight and small-sized batteries. Meanwhile, the service life of the battery also needs to be considered to ensure that the replacement cycle is not frequent. Acoucou LiFePO4 battery is only 1/3 of the weight of a lead-acid battery.

The batteries need to have a longer service life to reduce costs of maintenance and replacement frequency. Proper charging and discharging control, scientific battery management system, and reasonable usage environment can all extend the battery life.

Lead-acid battery vs. Acoucou LiFePO4 battery

 

Lead-acid battery

Lead-acid battery mainly has two types used for boats: flooded lead-acid battery and AGM battery.

 

  • Flooded lead-acid battery

The sulfuric acid in the electrolyte directly participates in the battery charging and discharging reaction process. In traditional lead-acid batteries, the remaining space in the battery compartment, excluding the plates, partitions, and other solid assembly components, is completely filled with the sulfuric acid electrolyte. The electrolyte is in an excess state, so it is called a flooded lead-acid battery. The battery plates are immersed in the sulfuric acid electrolyte.

Features:

It can handle high current consumption and provide stable power for a long time. Additionally, it has a wide operating temperature range, allowing it to work well in various weather conditions. It is cheaper and has a long lifespan.

However, it requires regular maintenance including checking and topping up electrolyte levels, cleaning terminals, and ensuring proper ventilation when charging.

 

AGM battery

AGM batteries differ from flooded lead-acid batteries in that the electrolyte is pure sulfuric acid aqueous solution and held in the glass mats, as opposed to freely flooding the plates. Thin glass fibers are woven into a mat to increase the surface area enough to hold a sufficient amount of electrolyte on the cells for their lifetime.

Features:

Pros: 

① Maintenance-free operation: AGM batteries are sealed, which means they do not require regular maintenance

② Longer service life: it has he stronger cycling charging capacity than regular lead-acid batteries and a longer service life.

③ Better vibration resistance: AGM batteries are more resistant to vibrations, making them suitable for use in vehicles or equipment that experience frequent movement.

Safety: AGM batteries are generally safer to use because they do not emit fumes or require ventilation.

Cons:

Higher cost: AGM batteries are generally more expensive than traditional lead-acid batteries.

Heavier than lithium batteries: AGM batteries are lighter than normal lead-acid batteries, but they are still heavier than lithium batteries.

 

 

Acoucou LiFePO4 battery

Now, LiFePO4 battery is becoming more and more popular and many people use it in their boats.

Features:

Pros:

① Safety: LiFePO4 batteries are known for their exceptional safety because the electrochemical properties of its positive electrode material are stable. Therefore, Acoucou LiFePO4 batteries adopt the most advanced BMS to protect the batteries and your safety, and they can be monitored anytime through Bluetooth.

Long Cycle Life: They often exceed 2,000 cycles, which means a longer lifespan. But Acoucou LiFePO4 batteries can be recycled up to 6000~15000 deep cycles in recommended conditions.

Stability: These batteries maintain a stable voltage during discharge, ensuring consistent performance throughout their lifespan.

Wide Operating Temperature Range: They can operate effectively in a broad range of temperatures and can be used for various scenarios. Acoucou LiFePO4 batteries can work between -20 ℃ and 45 ℃.

 

Acoucou LiFePO4 batteries Wide Operating Temperature Range

 

Cons:

① Cost: LiFePO4 batteries are generally more expensive to manufacture than some other lithium-ion batteries due to the materials involved.

② Not resistant to low temperatures: when the temperature is below -10 ℃, they decay very quickly, and can only maintain about 50% to 60% of normal battery capacity under -20 ℃.

Choosing the best battery for boats depends on your specific needs and application. But in terms of lifespan, space occupied, and environmental protection, LiFePO4 battery is better. According to the specific situation of the ship and the characteristics of different batteries, I believe you will ultimately make the right decision and choose the suitable battery.
