3. What are the disadvantages of 2 v solar street light?

- -

the recent China Daily website published a paper & other; Solar street light industry to ray, hidden secrets behind the battery & throughout; Referred to in articles, this article actually is. V solar street light. Though. V cheaper solar street lamps, but to let the poor service life. Boasts some manufacturers warranty years or five years, in fact, there is no basis and exaggerated, the actual service life in general only a year. All in all. V solar street light there are many disadvantages in practical application. Then by the solar street lamps factory money manager with you to understand what is its disadvantage.

. V solar street light is used commonly as a battery of lithium iron phosphate batteries, lithium iron phosphate batteries is a lot of domestic auto eliminated or used, these batteries exist the following problems:

a, the actual number of loop even lower than the battery cycles of

a new factory of lithium iron phosphate batteries cycles can reach several times, with the increase of cycling times, its internal chemical change, the whole life cycle are likely to have uncertainty. And solar street light industry using lithium iron phosphate batteries is the product of electric cars to use three years out, many cycles are already more than once, so from the chemical perspective, can be used to the life of the already can't guarantee.

2, performance is extremely unstable

because. V solar street light is used out of lithium iron phosphate batteries, so the capacity of batteries, such as voltage, internal resistance, cycle performance in very low and unstable state, not only can not meet the assembly requirements, and even for single use only, the attenuation of capacity and power rate is extremely unstable, the user experience will be very poor, and, similar to go to the wall, the lack of liquid lithium, analyse the internal defects, on behalf of the unstable security hidden trouble, the performance is very unstable.

3, high security hidden danger

to be eliminated under the lithium iron phosphate batteries are larger safe hidden trouble, the province because of its province after long time of charging and discharging circulation, age and chemical properties have no security, the security risks of high. And solar street light is the foundation engineering of the product, it is beneficial to the project, don't allow such a high risk and risk.

in general lighting. V solar street light attitude has always been: it is not recommended! Not recommended! 。 This violates the principle of market, as a good manufacturer of solar street lamps, lighting has been want to output high quality solar street light, so has been recommends using conventional V ternary batteries, solar street lamp, although a complete set of solar street light prices higher, but the service life is more guaranteed!
