How LiFePO4 Battery Save Money?

LiFePO4 battery is a very popular battery now, which is welcomed by many people due to its excellent properties. Whether it is solar energy storage, marine energy storage, uninterruptible power supply or DIY projects, LiFePO4 batteries are becoming the most talked-about type of batteries. But relatively, many people will also be discouraged by its relatively high price. Is the LiFePO4 battery worth it?

The answer is: well worth it, and choosing a LiFePO4 battery will not only give you a great performance experience, but it will also save you money over time.

How LiFePO4 Battery Save Money?

The key to saving money with LiFePO4 batteries is their extremely long lifespan and a high number of cycles. The most common LiFePO4 battery, after normal use and reasonable maintenance, can reach a lifespan of more than 10 years and a cycle life of more than 4000 times. And high-quality LiFePO4 batteries can reach a lifespan of more than 15 years and a cycle life of more than 6,000 times under normal use, and even batteries with more than 8,000 cycles exist. The long lifespan means that the battery does not need to be replaced frequently, which means that the usage time of one purchase is equal to the purchase of several other batteries, which is why the up-front cost of LiFePO4 batteries is higher.

But not only that, the LiFePO4 battery, as a kind of lithium battery, basically does not need maintenance, which is very different from some lead-acid batteries (such as FLA batteries). LiFePO4 batteries only need to pay attention to the oxidation of the battery terminals and whether the wiring is loose, and basically, no maintenance is required. FLA battery maintenance requires fluid injection, which costs a lot of money and time. More importantly, LiFePO4 batteries have no memory effect.

If installing the battery also requires hiring a professional to install it, there will also be some additional gaps. For up to 10 years, LiFePO4 batteries basically only need to be installed once. And some batteries may need to be installed multiple times in 10 years because each replacement means a disassembly and an installation, which will greatly increase labor costs.

The last point is that if you use LiFePO4 batteries in photovoltaic or wind systems, you will find even more savings. Since LiFePO4 batteries support more than 80% DOD discharge and allow high-speed charge and discharge, it means you can store more energy. In some areas, the surplus electricity produced by oneself is allowed to be fed back to the local power grid, so that electricity price reductions or incentives can be obtained, and more areas allow electricity to be exchanged for cash.

In this case, the money-saving ability of the LiFePO4 battery can be said to be very good, and it can even help you make money. Of course, if there is no photovoltaic or wind power system, it is simply used as energy storage, which can be charged when the electricity price is low and discharged when the electricity price is high, which can also effectively save costs.

Benefits of LiFePO4 Battery

LiFePO4 battery is a kind of battery that is very suitable for low-power scenarios, which makes the disadvantage of not very high energy density can be forgiven, making it one of the best lithium batteries. The benefits of LiFePO4 batteries are many:

  • Long lifespan, basically more than 10 years.
  • Many cycle times, which can reach 4000 to 8000 times.
  • Smaller size and weight.
  • Can be charged and discharged at high speed. And support more than 80% DOD discharge.
  • No maintenance required.
  • Extremely safe. It won’t explode even in bad conditions.
  • It has no memory effect and is basically not affected by the Peukert effect.
  • Has good temperature performance. It can operate normally in both high and low temperature, but it should be noted that low temperature (below 0°C) does not allow charging.
  • Very environmentally friendly. Not manufactured with hazardous materials.


There is no doubt that LiFePO4 battery is one of the best batteries available today, and their properties are indeed suitable for energy storage. Although the initial cost is relatively large, its excellent performance and very long life have made many people pay for it, and many people have benefited from it. LiFePO4 batteries are also really cost-effective compared to other batteries and are saving your wallet for a long time.
