Why our company use A Grade LifePO4 Battery?

A Grade Battery means good battery Consistency ,which is very important to Solar Lights. Battery Consistency includes:

1.Voltage consistency

2.capacity consistency

3.Internal resistance consistency.

1.Voltage consistency:

If there is a difference in the voltage of different cells in a battery pack, especially for a battery pack with a parallel circuit, the high-voltage cells will charge the low-voltage cells and conduct current in the battery pack circuit. This process will cause energy loss. Although the capacity of low-voltage battery cells has been slightly increased, the capacity of high-voltage battery cells will be greatly reduced.

2.Capacity consistency:

The inconsistent capacity of the battery cells will cause individual batteries with lower capacity to be over-discharged first, resulting in a decrease in the performance of the battery cells, thereby affecting the capacity performance of the battery pack.

3.Consistency of internal resistance:

It has been learned in middle school physics textbooks that batteries have internal resistance. The so-called internal resistance means that when the battery is discharged to form a current loop, the battery itself has resistance. Although this resistance is very small, the internal resistance of the battery will also lose part of the current energy in the long-term high-power continuous discharge configuration. of.　This is also the reason why the battery generates heat. Due to the existence of internal resistance, electrical energy such as current is converted into heat energy.

It will make the battery undercharged, the discharge time is short, and the solar lamp has a short working time. The battery lifespan is short.

We know that the Labor cost is very high in most countries ,especially in Developed countries. Therefore, a good battery not only guarantees the stable working performance of the solar street lamp, but also a long service life. And can greatly save maintenance costs
