Does the LiFePO4 Battery really worth it?

Does the LiFePO4 Battery really worth it? - Tewaycell

LiFePO4 battery is currently the most popular battery, its relatively good performance and long life fascinated many people. But there are also many people who are skeptical about it, and many people are still considering it.

What is LiFePO4 Battery?

LiFePO4 battery is a kind of lithium-ion battery with a voltage of 3.2V. It is a battery composed of lithium iron phosphate positive electrode and graphite negative electrode. Of course, it also contains a compound separator and electrolyte. At present, there are 3 types of LiFePO4 batteries, cylindrical, prismatic, and pouch. Among them, the prismatic LiFePO4 battery is the most popular one. Due to its efficient use of space and large single energy, it has been considered by battery DIY enthusiasts. It is the best kind of LiFePO4 battery.

Application Scenarios of LiFePO4 Battery

Application Scenarios of LiFePO4 Battery

LiFePO4 battery is one of the most widely used batteries at present, which is related to its own excellent and ultra-high safety.

Home energy storage: LiFePO4 battery is the most suitable battery whether it is a separate energy storage system or combined with a photovoltaic/wind system, and its excellent performance can ensure that a large amount of energy is stored for use.

RV: In the RV field, LiFePO4 batteries are the most popular. Higher performance allows you to do more activities on the RV, like cooking, making coffee, turning on the air conditioner all day, using the hair dryer… Plenty of power can meet the needs of almost any device. RV is well worth upgrading the battery to LiFePO4 battery.

Marine boats: Similarly, when sailing, the demand for electricity will be higher, and LiFePO4 batteries can be well qualified for this position with a waterproof casing.

Signal base station: In this case, the LiFePO4 battery will be used as an uninterruptible power supply (UPS) to ensure continuous power supply.

Golf carts: Golf carts are generally equipped with lead-acid batteries, but after upgrading them to LiFePO4 batteries, the golf carts will have longer battery life and faster speeds, which is the advantage of using LiFePO4 batteries.

Electric bicycles: In the same way, as long as the electric bicycles are replaced with LiFePO4 batteries, the battery life and speed will be significantly improved.

Electric vehicles: At present, LiFePO4 batteries are relatively rare in electric vehicles, but the good news is that some electric vehicles are preparing to use LiFePO4 batteries, such as Tesla as we know it. With the increasing energy density of LiFePO4 batteries, more electric vehicles will choose LiFePO4 batteries.

DIY projects: Since LiFePO4 batteries are very safe, they are very suitable for use in DIY projects. Of course, the reality is that many people have already chosen to do so.

LiFePO4 battery can be used in so many scenarios, which is inseparable from its own excellent performance and some unique properties.

Unforgettable Benefits of LiFePO4 Battery

The popularity of LiFePO4 batteries is never just talk, some of its own properties are enough to support its good reputation.

Has an extremely long life and cycle times. Under the premise of normal use, the LiFePO4 battery has a lifespan of more than 10 years and a cycle number of more than 4000 times. Some very high-quality LiFePO4 batteries can even reach a lifespan of more than 15 years and a cycle number of more than 7000 times.

Lighter weight and smaller size. Compared with the lead-acid battery, another old-fashioned battery, LiFePO4 battery has a smaller volume and lighter weight under the same capacity, which is useful in some places where space is required.

The overall cost is lower. Although LiFePO4 batteries have been criticized for their high up-front cost, considering the service life, they are indeed the most cost-effective batteries.

Support high-speed charging and discharging. This means that charging and discharging can be done in a very short time without waiting too long.

Allows deeper discharge. LiFePO4 batteries support more than 80% DOD discharge, and there are even deep cycle batteries that support 100% DOD discharge, which means more usable capacity.

There is no memory effect. Under the premise of normal use, there will be no memory effect, and efficient performance can be maintained to the greatest extent.

The self-discharge rate is low, and the storage is relatively simple. The monthly self-discharge rate of a normal LiFePO4 battery is about 3%, and it can keep 50% SOC for several months.

Very environmentally friendly and safe. The materials used in LiFePO4 batteries are clean and pollution-free, and are environmentally friendly. And the positive electrode adopts an olivine structure, and the chemical properties are very stable, which results in an exceptionally safe battery.

Basically no maintenance is required. It is only necessary to daily check whether the battery terminals are oxidized and whether the wiring is loose.

High temperature performance is guaranteed. Excellent safety allows LiFePO4 batteries to be used normally at higher temperatures.


LiFePO4 battery is a kind of battery worth considering. Its excellent performance and strong safety make more and more people start to use it. Although there are still many lead-acid battery advocates who have been resisting LiFePO4 batteries, it is undeniable that many former lead-acid battery loyal users have switched to LiFePO4 batteries and gained benefits that were not available in the past. All in all, people will finally find the flash of LiFePO4 batteries.
