Two Ways to teach you how to choose the best solar street light battery

In the production of lithium batteries, adding a protective plate to the lithium battery body can make the lithium battery have an overcharge and over discharge effect. The lithium battery itself has high power endurance.

 Lithium batteries do not contain toxic substances such as lead, mercury and cadmium.
There are 4 type of battery use in solar street light
1)smf battery : 1 year life bulk in size 12v
2)lead acid battery : 1year life large size and weight.12v
3) Lithium Ion Battery : 3-5years life and compact size 11.1v
4) lithium iron phosphate battery (LiFePo4) : 8-10 years life compact size, 12.8v

In summary, the above is the advantage of using lithium batteries for solar street lamps. Lithium batteries can be cyclically charged and discharged more than 1500 times, with long life, high safety performance, and strong resistance to low and high temperatures. On the basis of our selection of lithium batteries, the use of intelligent balancing technology and intelligent dual protection technology to make the battery life longer.

Nowadays,  All in One Integrated Solar Street Lights batteries using Lithium Iron Phosphate Battery (LiEePO4) and good quality battery compare to Lithium ion Battery.

With the problem of the service life of new energy vehicle batteries, many LifePo4 batteries have been eliminated.Under the conditions of non-standard national policies and regulations and the immature use of echelon utilization technology, many manufacturers have to deal with these batteries at a low price, even by tons. Sale, so the price is extremely low, and some costs may vary from 1/5-1/10 of the normal battery.

There are currently 4 grades of LiFePo4 batteries on the market, A-class LiFePo4 battery, B-class LiFePo4 battery, li-ion battery, and D-class LifePo4 battery(Already eliminated Or have been used LifePo4 battery).

So where did these eliminated LifePo4 batteries go? For what use? It is understood that many eliminated LifePo4 batteries have just flowed into the solar street light industry, Unfortunately, more than 90% of solar street light manufacturers on the market now use this LifePo4 battery that has been eliminated which cause another disadvantage to the solar street light market that already lacks standards. The industry is more uneven, and the gap between prices and quality is greater. 

So how we distinguish these 4 types of LifePo4 batteries.

The internal resistance and voltage of the battery cells are very different, so the consistency between the batteries will be much worse, such products will have a greater hidden danger after serial and parallel connection.

Therefore, the capacity, voltage drop, internal resistance, circulation and other performance of the eliminated cell are extremely low and unstable, which not only does not meet the assembly requirements, but even if it is used for a single use, its capacity attenuation and power-down rate are extremely low. Stable, the user experience must be extremely bad,
