Advantage of LiFePO4 Battery
1

Longer Lifespan
LFPs have a longer lifespan than any other battery. A deep-cycle lead acid battery may go through 100-200 cycles before its performance declines and drops to 70–80% capacity. On average, lead-acid batteries have a cycle count of around 500, while lithium-ion batteries may last 1,000 cycles. In comparison, the LFP battery in Our Portable Power Station has a cycle life of 3,000+ before performance drops to 80% of its original capacity. They will still function well after this period but at a slightly lower capacity.

2

Improved Safety
LiFePO4 is a safer technology when compared to Li-ion and other battery types. Specifically, they don't have the issues of toxic fumes and off-gassing associated with Lithium-ion and lead-acid. LFPs have improved the technology to avoid these dangerous issues, using a non-flammable electrolyte as part of the battery's chemistry.
Li-ion batteries may experience thermal runaway, overheating, and combustion. Lead acid batteries may produce toxic fumes, such as hydrogen sulfide. These issues are hazardous to safety and health.
LiFePO4 batteries do not emit gas like lead-acid batteries do. You can safely store and operate LFPs in sheds, garages, or inside your home.
LiFePO4 batteries also don't use toxic chemicals or heavy metals in their chemistry, which allows for safer handling and disposal. Lead-acid batteries can leak harmful liquids without proper care.
In the past, solar and backup batteries had to be stored outdoors in well-ventilated spaces to prevent any safety issues from harming the users. Not so with off-grid power solutions that run on LFPs.

3

Fast Charging
You can charge LiFePO4 batteries much more quickly compared to other battery types, typically within 1-2 hours using AC power and 3-6 hours using solar panels. The actual charging time depends on several factors, including battery capacity, current, and charging method.

4

Wider Operating Temperature Range
LiFePO4 batteries have an operating temperature range between -4°F and 140°F (-20°C to 60°C). The temperature range allows them to perform well even in climates or conditions with extreme cold or heat.
Operating any battery outside its recommended temperature range can negatively impact its performance and lifespan. High temperatures can accelerate the battery's aging, reduce capacity, and increase the risk of thermal runaway. Low temperatures, on the other hand, can reduce the battery's efficiency and capacity.

5

High Energy Density
LFPs have a higher energy density compared to some other battery types. Energy density refers to the amount of energy a battery can store per unit of volume or weight. LiFePO4 batteries have an energy density of around 130-140 Wh/kg - 4 times higher than the typical lead-acid battery density of 30–40 Wh/kg.
Some Li-ion batteries have a slightly higher energy density than LiFePO4 but also have safety issues and shorter lifespans.

6

Low-Maintenance
LiFePO4 batteries are low-maintenance compared to other battery types. Lead-acid batteries require you to check the electrolyte levels and refill them with distilled water. They're also finicky when it comes to charging levels and storage conditions.
LFP batteries don't require any electrolyte or water level maintenance. You should certainly keep an eye on vitals like charge and discharge levels, voltage, and related stats, but you shouldn't have to spend too much time taking care of your battery.

7

Low Self-Discharge Rate
LFP batteries have a lower self-discharge rate than Li-ion and other battery chemistries. Self-discharge refers to the energy that a battery loses when it sits unused. The low self-discharge rate makes LiFePO4 a better choice in home backup power systems. The batteries can sit unused for months while still being ready for use when a blackout hits. However, it's important to remember that all battery types will discharge over time, even when not in use. Proper storage and maintenance of LiFePO4 batteries will ensure optimal performance and lifespan.

 

Application of LiFePO4 Battery

Boats/Kayaks

Electric Vehicles
Under the circumstances of growing environmental concern, most progressive countries are in the process to increase the usage of electric-powered bikes to reduce emissions. The most integral part of the electric vehicle is the battery that acts as an energy source to drive the electric motor. In recent days, lead-acid batteries are being replaced with LiFePO4 batteries for electric tricycle application, which is because of the tremendous advantages of LiFePO4 batteries such as fast charging and discharging rate, wider temperature range, and longer cycle life. It is obvious that to match up with the standard of internal combustion (IC) engine, the electric cars must have a higher acceleration at the beginning that can be perfectively delivered by the LiFePO4 battery as it has a high discharge rate and accordingly, a higher output current. On the other hand, a higher charging rate compared to lead-acid battery makes it easier for electric vehicle owners to charge the vehicle in a shorter time. Moreover, the performance of the LiFePO4 battery does not deteriorate much with the variation in temperature. For example, at 0°C, a lead-acid battery's capacity is reduced by up to 50%, while a LiFePO4 battery suffers only a 10% loss. Therefore, LiFePO4 batteries are the best choice in an extremely cold or hot region.
Electric Golf Caddy
Bioenno Power LiFePO4 batteries can be used to power electric golf caddies which are used to carry golf clubs across golf courses. LiFePO4 batteries are less than half the weight of traditional lead acid batteries making them ideal for electric golf caddies, with tremendously enhanced cycle life.
Energy Storage
LiFePO4 batteries when combined with converters and inverters can be used as an energy storage solution which can power many types of electrical loads in environments where there is no access to electricity. For example, many portable electronics can be charged using LiFePO4 batteries including laptops and smart phones. Many of our customers are using Bioenno Power LiFePO4 batteries in combination with inverters/converters for powering various electrical loads.
Solar Photovoltaic System
Solar photovoltaic is a renewable energy source that converts sunlight into electrical energy. The generated electric energy can be utilized to meet the load demand during the daytime, but, during the night time, there will be no generation of the solar system. Therefore, the excess energy during the day time can be stored in the battery storage system to further use at night time. In this regard, LiFePO4 batteries can be used with solar charge controllers as energy storage elements in the solar system. Compared to lead-acid batteries, LiFePO4 batteries are advantageous in solar application mainly due to outstanding cycle life. On average, LiFePO4 batteries can last for 1,000 to 3,000 charge and discharge cycles without deferring their performance. On the other hand, lead-acid batteries range only 200 to 1000 cycles. Basically, LiFePO4 batteries have a life span of approximately 5-10 years in comparison with lead-acid batteries that need to be changed every 1-3 years. Comparative analysis as conducted by the researchers established that LiFePO4 batteries have low loss and extended cycle life with a lower storage depletion rate as compared to lead-acid batteries. Moreover, LiFePO4 batteries do not require as much maintenance and replacements as compared to lead-acid batteries and these batteries are also more environmentally friendly.
Communication Equipment
In the context of communication technology, LiFePO4 batteries are gradually replacing other types of batteries to be used as radio communications equipment due to their longevity, lightweight, safety profile, and less maintenance. In comparison to lead-acid batteries, the weight and size of LiFePO4 batteries are significantly less, making this battery most preferable for a communication system that demands less space for installation. Moreover, LiFePO4 battery systems are generally made up of smaller, easy to handle modules of sizes from 2-4 kWh, which gives much more flexibility in designing a low voltage communication system. LiFePO4 batteries are also safe and chemically stable. Therefore, in case of hazardous events, such as collision or short-circuiting, they won't explode or catch fire, significantly reducing any chance of harm.

The general purpose equipment include audio amplifiers, cell phones, computers, portable projectors, etc. Instrumentation equipment includes various types of sensors used to monitor the environment.

 

Factors to Consider When Buying LiFePO4 Battery

Capacity
The capacity of a battery represents how many appliances it can power and for how long. It is measured in Watt hours (Wh). The capacity is the primary factor to consider and the main factor that drives up the LiFePO4 battery cost. Users often get confused when they cannot see a Wh rating mentioned on the battery. Instead, they find voltage and Amp hours (Ah) ratings.
Value For Money
Many users focus on 'price' as the deciding factor. However, a better factor to consider should be the value for money of the battery.
Lead acid batteries are the cheaper option in the market today. However, their lifespan is only one-tenth that of a LiFePO4 battery. While LiFePO4 batteries can last over 10 years, a lead acid battery will run out after a year or so. Additionally, there is always the risk of cheaper batteries running out while on the job.
Therefore, opt for value for money instead of the price as the deciding factor. It can save you countless trouble in the long run. This brings us to our next important criterion.
Battery Life
It is essential to consider how many years a battery will last. You can save money and buy lead-acid batteries if you want a short fix for a few months. However, most users do not want that. Instead, they require a long-term solution.
A LiFePO4 battery is the best option in terms of battery life. A good quality LiFePO4 battery will easily last upward of 10 years. AGM and conventional lithium-ion batteries can work well for three to four years.
Cycle Life
Cycle life means the number of charge and discharge cycle that your battery can undergo. A longer cycle life means a battery will last longer. Batteries do not come with a suggestive lifespan on the box. However, they do mention a cycle life. Choose an option with a longer cycle life for a better return on investment.
Warranty
Warranty is a good indicator of the build quality of the battery and its lifespan. Lead acid batteries come with a 6-month warranty. Therefore, they are workable for up to a year until they demand replacement. LiFePO4 battery is a whole different game.
You will find different kinds of warranty periods with different LiFePO4 manufacturers. Eco Tree Lithium is the leader in the game as it provides a warranty of an astonishing 6-year. You can expect the Eco Tree Lithium batteries to easily work for over 10 years with a warranty like that.
Depth of Discharge (DoD)
Depth of Discharge (DoD) is a significant factor that makes people switch from existing lead acid batteries to lithium iron phosphate batteries. Depth of discharge denotes the usable capacity of the battery.
For instance, the depth of discharge for lead acid batteries is 50%. Therefore, you can use these batteries to 50% of their capacity. After that, they will require charging. However, for Eco Tree Lithium's LiFePO4 battery, the DoD is a whopping 100%. You can use LiFePO4 through the full rated capacity.
Here is an example for putting things in perspective. Suppose your capacity requirement is 200 Ah. You can meet this requirement with a 200 Ah LiFePO4 battery. However, you will need a 400 Ah battery capacity if opting for a lead acid battery due to its half depth of discharge.
Maintenance Requirements
Every battery has a distinct maintenance requirement. Lead acid batteries have many requirements like electrolyte top-ups and venting the buildup gases. Fortunately, maintenance of LiFePO4 battery is much simpler and easy.
Dimensions
Battery dimensions are important for applications like motorhomes. The battery compartments can accommodate a particular size battery bank. LiFePO4 battery has prefixed size groups to denote the standard size of the battery. Match the lithium battery group with your requirement.
Weight
Weight is not always on the priority list of important parameters. However, some users find having a lighter battery preferable. If that is the case, any lithium battery is a better buy over a lead acid battery. For instance, a lead acid battery pack of 500 Ah can weigh around 850 kg. The same job can be done by a 250 Ah lithium-ion battery weighing 210 kg. This means a considerable difference in weight.
The main differences come from the eliminated weight of lead plates and electrolytes. Additionally, lithium iron phosphate batteries have lighter electrodes.
Safety
Safety becomes essential when you operate your battery near life and property. There have been instances where lead acid battery leak fluids that cause corrosion of the battery and nearby appliances. Conventional lithium batteries have fire and explosion hazards with them. However, lithium iron phosphate batteries are made using very stable compounds of iron and phosphate. These will never explode or cause fire injury.
Voltage Rating
The voltage of the battery pack is important because it determines its usability. For instance, you cannot replace a 24V battery with a 48V battery and vice versa. Every type of voltage rating has a distinct application, advantage, and disadvantage. If you are replacing your old batteries, you will need to find old voltage rating and match new batteries with the same rating for a constant voltage.
Cold Weather Usage
All batteries are known for performance stuttering in extreme temperatures. Freezing conditions can lead to battering running flat. These batteries often do not recover once the temperature toll takes place. Therefore, find the optimal temperature range of the battery. Better yet, choose Eco Tree Lithium batteries with an inbuilt heater for cold weather.
Features
Modern batteries come with many features that add to the convenient user experience. Take the case of this battery. It has a Bluetooth feature to check your battery stats remotely. You do not have to open the battery compartment. You don't have to use a multimeter to check the voltage and current parameters. You can manage the battery remotely from a Bluetooth device.
Other secondary features can include LED indicators for the charging system. Having a handle to transport the battery is also a handy feature to have.
Battery Management System (BMS)
Always choose a LiFePO4 battery that comes with a BMS. A battery management system has a lot of safety protocols against potential hazards. All batteries are prone to irreversible overcharge and over-discharge damage. BMS protection measures cut off the circuit to eliminate any possibility of damage.
Environmental Impact
Modern energy technologies are pushing towards greener initiatives. It is recommended to choose an environmentally friendly battery option. For instance, cobalt-based batteries (like lithium cobalt oxide) are not environmentally friendly. This is because cobalt is rare and toxic in nature. LiFePO4 battery is one of the greenest battery out there.
Toxic
Cobalt and lead come in toxic heavy metals category. These materials can cause health hazards if they come into human contact. Therefore, batteries that include these metals are considered unsafe. This includes all lead batteries. However, a lithium iron phosphate battery does not have any toxic substances in them.
Additionally, lead acid chemistry leads to the emission of toxic gases. You might be familiar with the pungent smell that often comes from lead batteries. Therefore, choose a battery that does not have any such risk. You will never need to vent lithium iron batteries because it releases no toxic gases.
