What are the important indicators for measuring the performance of lifepo4 battery 12v 200ah?

Users are most concerned about the quality of the battery, then measure the performance of lifepo4 battery 12v 200ah, there are those important indicators?

First, charge and discharge rate:

the higher, the better "C" is a special symbol that describes the charge and discharge current of a lifepo4 battery 12v 200ah. The 1C discharge represents the amount of current that can be placed from full charge to empty within 1 hour. The iPhone 6 battery capacity is 1810mAH, then the 1C discharge current of this battery is 1.81 amps.The battery capacity of each battery used in the BYD e6 electric car is 200AH, then the battery 1C discharge current is 200 amps. If a battery is discharged at a high rate, it usually emits less energy than a low rate.

Second, the number of charge and discharge cycles: the more, the better

2000 times is a common value of lifepo4 battery 12v 200ah, and the number of charge and discharge of lifepo4 battery 12v 200ah made according to different materials ranges from 1500 to 3000 times. The specific meaning of this value may be slightly different for each factory, which can be roughly understood as: the charge and discharge rate specified by the manufacturer (such as 1C discharge, 0.3C charge; each time from 0% charge to 100%, according to this cycle) After 500 cycles, the battery capacity is still 80%. The relationship between the number of charge and discharge cycles and the habit of use is very strong.

Third, internal resistance: the smaller, the better

This parameter changes with the load and weight, temperature and other factors. As the lifepo4 battery 12v 200ah life decreases, the internal resistance also increases. The battery with the lower internal resistance can be charged and discharged at a high rate. The internal resistance of the 18650 battery is about 50mΩ, and the power type 18650 battery is about 15mΩ. I want to know how much internal resistance needs to be measured with special equipment, and ordinary multimeters can't use .

  Fourth, battery consistency

The higher the consistency of the capacity, internal resistance, charge and discharge curves of the lifepo4 battery 12v 200ah produced by the same material and the same process, the better. It is critical that the battery can form a battery pack on a large scale. The larger the battery pack, the higher the consistency requirement.
