Appeared in 1996, Lithium Ferro Phosphate technology (also called LFP or LiFePo4) is supplanting Other technologies because of its technical advantages. This technology is implanted in traction applications, but also in energy storage applications such as self-efficiency, Off-Grid or UPS systems.
Major advantages of Lithium Iron Phosphate:
Very safe and secure technology (No Thermal Runaway)
Very low toxicity for environment (use of iron, graphite and phosphate)
Calendar life > 10 ans
Cycle life : from 2000 to several thousand (see chart below)
Operational temperature range :up to 70°C
Very low internal resistance. Stability or even decline over the cycles.
Constant power throughout the discharge range
Ease of recycling
Estimated Lifecycle for Lithium Iron Phosphate technology (LiFePo4)
Lithium Iron Phosphate technology is that which allows the greatest number of charge/discharge cycles. That is why this technology is mainly adopted in stationary energy storage systems (self-consumption, Off-Grid, UPS, etc.) for applications requiring long life.
The actual number of cycles that can be performed depends on several factors:
Level of power in C-Rate
Depth of Discharge (DOD)
Operational environment: temperature, humidity, etc.
In the standard environments, and for 1C cycles, we can get from the chart the below life cycle estimation for LFP

Q: What is the life expectancy of a Lithium battery?
A: The typical estimated life of the Lithium Iron Phosphate (LiFePO4) battery is 5-15 years or 2000 to 8000 charge cycles. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
Q: If I want to charge LiFePO4/Lithium Ion battery, which already has PCB, would a normal SLA controller work fine?
A: For LiFePO4 / Lithium-Ion battery, we always recommend using LiFePO4/Lithium-Ion Solar Controller. Especially if you are using the battery as UPS (back up power supply). The Lead-Acid solar controller will constantly provide pulse current to the battery. In the long run, it might damage the PCB. So the PCB won't be able to protect the battery when it should be.
Q:I am a distributor. Can I cooperate with battery warehouse for a long time?
A: Yes, Individual pricing for large scale projects and wholesale demand is available
Q: Why hasn't my ups or FedEx transportation number been updated?
A: This is normal, in countries with tariffs, our packages need to pass the customs of your country before they can be delivered to the local UPS or FedEx. Once they pass the customs and update the transportation number, you can usually receive the goods within 3-5 days.
Q: Are the cells I bought balanced?
A:we know the importance of maintaining the consistency of each cell in the battery pack, so we will match and balance all cells to ensure that the internal resistance, voltage, and capacity of cells are completely matched and balanced before delivery. This process is very necessary.
