Advantages of Lithium Iron Phosphate Battery for Marine Use

Lithium iron phosphate battery (LiFePO4), a lithium-ion battery technology, is a safe battery that is superior to that of lead-acid battery in terms of storage capacity, consistent high power, longer shelf life, weight and quick charging. All of these properties have made the LiFePO4 battery an ideal choice for marine use. They are the safest type of lithium-based batteries that does not overheat and does not pose any environmental hazard. Lithium iron phosphate battery manufacturers can help you to understand the functioning and capability of battery banks, thus, connect with them before making a final decision.

Listed below are the advantages of using lithium iron phosphate battery pack in marine vehicles:

• The lifecycle of a LiFePO4 battery is 2000 – 4000 cycles and can be discharged to 90%. This feature is extremely significant in the case of water transport.

• LiFePO4 battery has a constant discharge of voltage. These batteries stay at a voltage of 13 - 13.4V until the discharge up to 95% and then voltage falls down quickly. Whereas, a Lead-acid battery decreases its voltage from 13V to below 11.5 V. Hence, a LiFePO4 battery operated appliance operates efficiently until the full energy is discharged.

• Since LiFePO4 battery can safely, draws down up to 95% compared to 50% of a lead-acid battery, which means fewer LiFePO4 batteries achieve the same power. The battery weight of the LiFePO4 battery combined with capacity means significant reduction in the lithium iron phosphate battery pack weight. The LiFePO4 battery occupies only 40% space as that of a lead acid. Lighter and compact batteries will help in the easy mobility.

• LiFePO4 batteries are generally safe when compared to other lithium-based batteries. The Battery Management system takes care of the overcharging and discharging rates. LiFePO4 battery does not have the risk of emitting noxious fumes as compared to that of lead-acid batteries.

• LiFePO4 batteries can be stored in temperatures between -25oC to 40oC. The charging of a LiFePO4 battery below -20oC can degrade the battery. It is advisable to remove the negative terminals during winter or when the battery is kept in long storage.

• The lithium iron phosphate battery manufacturers, owing to its long lifecycles, recommends it as a best investment that can be made for a speed boat.

To buy LiFePO4 battery is indeed an expensive choice, but its advantages over the lead-acid batteries or other lithium-based batteries can overlook this additional cost. So, invest smartly and effectively.

Top 5 Applications of a Lithium Iron Phosphate Battery

Lithium iron phosphate batteries (LiFePO4) are increasingly becoming popular among customers due to various advantages over lead –acid batteries. The LiFePO4 batteries are a superior choice due to their qualities like higher specific energy capacity, long life cycles, compact size, high thermal and chemical stability, improved cost performance, and enhanced charge – discharge rate and safety. Before you buy LiFePO4 battery, read the following sections to know more about its applications in various industries and sectors:

1. Electric vehicles

Lithium iron phosphate battery has a higher discharge rate that is required for acceleration making it suitable choice for all electrical vehicles. The electric bicycles and cars are utilizing LiFePO4 batteries extensively owing to its lower weight and long life. It is also used in recreational vehicles, like caravan or motor home, as well as in boats.

2. Energy storage applications

Lithium iron phosphate batteries when used in combination with converters and inverters can provide power to electrical loads when the power supply is disrupted. The lower discharge rate of a LiFePO4 battery makes it ideal for storing energy without much loss. Many electrical loads, which may include your laptops or mobile phones and most of the household electric appliances can be powered using a Lithium Iron Phosphate Battery in combination with an inverter or a converter.

3. Motor boats

The LiFePO4 battery, owing to its lightweight and enhanced lifecycle, is increasingly preferred for powering small boats and kayak motors. The low self-discharge property gives the LiFePO4 batteries long shelf life as well as good winter storage. In addition, these batteries are generally plug compatible with lead-acid chargers making it a drop-in replacement.

4. Solar energy system applications 

LiFePO4 batteries can be combined with solar panel and solar controllers to develop a perfect solar energy storage solution. The solar panels charge the LiFePO4 battery and also provide power to the electrical loads. The outstanding shelf-life of LiFePO4 battery is a significant feature for the solar application.


5. Communication Equipment

The radio communication equipment like ham radio have been traditionally using lead-acid and Nimh batteries that are being fast replaced by LiFePO4 batteries. The longevity and number of charge cycles are the qualities that encourages you to buy LiFePO4 battery for this equipment.

Many other items like solar powered lights, flashlights, portable motor-driven equipment, industrial sensor systems and emergency lightings are working on lithium iron phosphate batteries.
