Discover the many advantages of LiFePO4 batteries or order the battery you need directly from our wide range!

What are LifePO4 batteries?

LiFePO4 batteries are composed of lithium, iron and phosphate. It is a battery with high energy density relative to its volume and weight, and great resistance to extreme temperatures. Compared to other well-known lithium battery technologies, such as LiCoO2 (lithium oxide cobalt), LiFePO4 is also a lot safer. Whereas other lithium batteries are prone to ignite when overcharged, LiFePO4 batteries do not have this problem. The battery has many advantages over other battery types.

Advantages of lithium iron phosphate batteries

As mentioned, lithium iron phosphate batteries have many advantages. We list them for you:

Utilize more than full capacity

A LiFePO4 battery can use more than 100% of its rated capacity. A 100 Amp-hour (Ah) LiFePO4 battery, for example, can deliver more than 100 Ah. For a 100 Ah lead-acid battery, the usable capacity is no more than 30 to 50 Ah.

Long lifespan

LiFePO4 batteries last more than 2000 cycles at an average discharge of 100%. This can even go up to 8500 cycles if the battery is discharged to 30%! LiFePO4 batteries are thus true cyclic powerhouses that continue where other batteries stop. By comparison, a traditional lead-acid battery will last at most 300-500 cycles. The long service life means that a LiFePO4 battery is also a smart choice economically!

Great ease of use

To achieve the lifespan given above, virtually no maintenance is required. Whereas with lead-acid batteries it is important to maintain and use them properly, this plays virtually no role with LiFePO4 batteries. They can be discharged to 100% and do not always need to be fully charged. This saves a lot of worry!

Fast and easy charging

LiFePO4 batteries charge at lightning speed to 100% of their capacity. With a normal charger, charging takes only an hour. With a powerful charger, the lithium iron phosphate battery is even charged to full capacity within half an hour. If the battery is not 100% charged, it is not a problem. This is a significant advantage over lead-acid batteries, where incomplete charging can lead to damage. Also, lithium iron phosphate batteries do not have an absorption phase to charge the last 20% of the battery. Thanks to the “Battery Management System,” the cells are charged evenly. After charging, the battery is immediately ready for use. This makes this type of battery very easy and flexible to use.

Temperature resistant

LiFePO4 batteries can withstand extreme temperatures. The loss of capacity is then minimal. At a temperature of -20 ˚C, the capacity of a LiFePO4 battery is still 80%, whereas with a lead battery it is only 30%. Even at high temperatures above zero, the lithium iron phosphate battery functions excellently.

Flat discharge curve

Batteries with this composition have an almost flat discharge curve. This means that they can always deliver the same output whether they are just charged or nearly empty. Even if they are already deeply discharged, LiFePO4 batteries can still deliver a very powerful peak charge.

Low weight, convenient size

LiFePO4 batteries are very light and small compared to lead-acid batteries: they weigh only a quarter of comparable lead-acid batteries. Due to their convenient size, they can easily be placed in many places. In addition, they can be placed in any position because there is no danger of leakage. Also, the room in which the LiFePO4 battery is placed does not need to be ventilated.

What applications are LiFePO4 batteries used for?

These versatile batteries are suitable for a wide range of applications thanks to their favorable properties. From marine applications to traffic systems and from energy storage systems to off-grid standalone systems. Wondering if LiFePO4 batteries are also the solution for your application?
