LF280K 3.2V 280Ah lithium iron phosphate LiFePO4 battery is a new model with an aluminum case, this battery cell has a super long cycle life of more than 12000times, have a stable performance used for ESS(energy storage system). All the cells we provide are brand new grade A with test reports and certifications.
Product Feature:
The LFP280K is a type of Lithium Iron Phosphate (LiFePO4) battery cell. LiFePO4 is a type of Lithium-ion battery that has gained popularity in recent years for its high energy density and long cycle life compared to traditional lead-acid batteries. Here’s a detailed guide to the LFP280K LiFePO4 battery cells.
Construction and specifications:
The LFP280K is a cylindrical cell that measures 28mm in diameter and 70mm in length. It has a nominal voltage of 3.2V and a capacity of 3Ah. The cell’s weight is approximately 72g.
Characteristics:
LiFePO4 cells are known for their high thermal stability and low risk of thermal runaway. They have a higher voltage and lower internal resistance compared to other types of lithium-ion batteries, which makes them a popular choice for high-power applications. The LFP280K has a relatively low capacity compared to other LiFePO4 cells, but it makes up for it with its high discharge rate, which is rated up to 15C.
Charging:
LiFePO4 cells should be charged using a dedicated LiFePO4 battery charger. The charging voltage for the LFP280K is 3.65V, and the maximum charging current is 1C (3A). It is recommended to charge the cell at a slow rate (0.5C or 1.5A) to extend its life cycle. The charging process should be monitored to prevent overcharging, which can cause permanent damage to the cell.
Discharging:
The LFP280K has a maximum continuous discharge rate of 15C (45A), which means that it can deliver its full capacity in just a few minutes. The cell’s discharge voltage should not fall below 2.5V. If it does, the cell may become irreversibly damaged and its capacity may be reduced.
Storage:
LiFePO4 cells should be stored in a cool, dry place with a charge level between 40-60%. It is important to avoid over-discharging the cells during storage, as this can cause capacity loss and reduce the overall life cycle of the cells.
Safety:
LiFePO4 cells are considered one of the safest types of lithium-ion batteries due to their high thermal stability and low risk of thermal runaway. However, it is important to handle the cells with care to avoid damage and to ensure their safe usage. Overcharging, over-discharging, and puncturing the cells can cause a fire or explosion.
The LFP280K LiFePO4 battery cells are a popular choice for high-power applications due to their high discharge rate and relatively low internal resistance. Proper handling and maintenance of the cells is crucial to ensure their safe usage and to extend their life cycle.
