As a new product of solar street lamps, lithium battery solar street lamps have been popular in recent two years and need to be installed in place. Inner Mongolia is installed in the northeast, and Anhui is also installed in Hunan and Hubei. Prices are different. Some street lamps cost 1500 yuan. Some street lamps cost 2000 yuan. The customer didn't know what to choose.

In particular, customers in Inner Mongolia or Northeast China asked why Guangya's lithium battery solar street lamps are much more expensive than those in the south. This place can still use the automatic heating function. The customer didn't believe it. As a result, a number of low-cost products were installed. As a result, some problems arose in winter. At that time, it was early winter. In the late winter, the whole army was basically destroyed. They are all broken, and there is no way to repair them. This is much more expensive than buying a qualified product, and it is my own responsibility.

This involves a question, whether the lithium battery of solar street lamp can withstand low temperature and how much temperature below zero can be used. Guangya tells you that in general, lithium batteries can be used at minus 30 degrees, but should not exceed minus 35 degrees. The problem is that the batteries can't be discharged even when they are good. The batteries manufactured in the south can only resist the problem of zero to minus 10 degrees. It is obviously not suitable for use in cold places.

Of course, the price difference between minus 30 degrees and minus 10 degrees is too big. A negative 10 battery can be used for 1 ah within 10 yuan, and a negative 30 battery can be used for at least 14 to 15 yuan. This is the third difference. If a street lamp is also 40ah, the low temperature resistance is 400 yuan, and the low temperature resistance is 600 yuan. This kind of battery is 200 yuan different, so the price is stuck.

Finally, I want to say that lithium battery solar street lamps can also be used in most areas at low temperatures, but the price is on the high side. Some people will ask this question in the future. It can be said that it can be used. It can also be used at minus 30 degrees, but the price is high.
