Lithium batteries are small in size, light in weight, and easy to transport. Compared with the lithium energy storage system and the lead-acid gel battery used in the all in one solar street light with the same power, the weight is about one-third and the volume is about one-third. In this way, transportation is easier, and transportation costs are naturally reduced.
Guangdong Super Battery New Energy Co., LTD produces high performance lithium battery for solar street lights using.
