Lithium iron phosphate battery is a very versatile lithium battery. If we choose an inferior lithium iron phosphate battery, which will lead to poor charging and discharging effects, and its service life will be less than expected. Through the following understanding of the necessary characteristics of high-quality lithium iron phosphate batteries, we can avoid some misunderstandings when choosing.

1. Good consistency

If a lithium iron phosphate battery with poor consistency has a protective plate, the battery capacity will be very low. In this way, it will cause the entire battery pack to neither fully release electrical energy nor fully absorb electrical energy due to a single cell. Over time, the life of the battery pack will be shortened. If the battery pack is not equipped with a protective plate, not only will there be a loss of capacity, but there may also be safety issues.

The method of testing consistency is to connect the cells to be tested in series, a group of 4 or a group of 6, do 1C charging and 3C discharge, and observe the difference in the rise and fall of the cells and voltage during the charging and discharging process.

2. The self-discharge rate should be small

Since lithium iron phosphate batteries are often used to power lithium-ion batteries, they consume a lot of power. This requires that the self-discharge rate of the battery pack should be less than 2% per month. To achieve this, the above-mentioned consistency requirements are indispensable. After passing the consistency test, the test method for the self-discharge rate is to fully charge the battery with the same capacity and let it stand for one month, and then measure its capacitance value.

3. Withstand high rate charge and discharge

A lithium iron phosphate battery pack that can withstand high-rate charge and discharge has a strong ability to charge and discharge quickly. For lithium iron phosphate batteries, they must be able to charge and discharge quickly to meet their requirements for power lithium-ion batteries. The test method is to use the highest rate to test the lithium-ion battery. If there is an obvious serious heating problem during the charging and discharging process, the battery quality is not good.

4. Long service life

As a general requirement, lithium iron phosphate batteries need to have 85% capacity after 2000 discharges at 1C, and 80% capacity after 3000 discharges. Of course, each manufacturer has different standards due to different technology levels and materials.

The test method is based on the data supplied by the manufacturer. As for how to judge whether the data supplied by the manufacturer is true, it also depends on whether the manufacturer has some certifications and specific services.
