What are the cycle times and real life of the lifepo4 battery pack?



What is the real life of a lifepo4 pack? The life of lithium battery packs is almost the same. Whether a lithium iron phosphate battery or a ternary lithium battery, the actual service life is related to the user's use and protection.



lead-acid and lifepo4 batteries


What is a lifepo4 battery?


Lithium iron phosphate battery is a kind of lithium-ion battery, which refers to the lithium-ion battery with lithium iron phosphate as the cathode material. It features high safety, high temperature, and good cycle performance.



What is the real life of a lifepo4 pack?

A long-life lead-acid battery has around 300 cycles, up to 500 cycles; the lifepo4 power battery has a cycle life of more than 2000 times. The lead-acid battery has the longest service time of around 1 to 1.5 years, but the lifepo4 battery has 7 to 8 years in the same operating conditions.

Advantages of the lifepo4 pack compared with the lead-acid battery:


Higher capacity

A single lithium battery cell has a capacity of 5ah to 1000ah (1ah=1000mah), and a 2v lead-acid battery cell has a small capacity range of 100ah~150ah.

Lighter weight

A lifepo4 battery pack of the same capacity is 2/3 the volume and 1/3 the weight of a lead-acid battery.

Fast Charging

The starting current of a lifepo4 pack can reach 2C, realizing a high rate of charging; The charging current of lead-acid batteries is generally required to be between 0.1C and 0.2C, so fast charging performance cannot be achieved.

Environment friendly

The lead-acid battery contains a large amount of heavy metal -- lead, resulting in the waste liquid. In contrast, the lifepo4 pack does not contain any heavy metal, which is pollution-free in production and use.

Highly cost-effective

Although the purchase cost of a lead-acid battery is lower than that of a lithium iron phosphate battery due to its cheap material, it is less economical than a lithium iron phosphate battery in service life and daily maintenance. The practical application results show that the cost performance of lithium iron phosphate batteries is more than four times that of lead-acid batteries.
