Currently the charging circuit of Harley is designed for AGM Battery, as lithium charging requires more stringent voltage and current, and the charging circuit is more sophisticated. Harley power usually supplies are charged with a constant current, but lithium is sensitive to overcharging. Lead acid is charged at a constant voltage. Lead-acid batteries are not afraid of open circuit, misconnection, short circuit, overload and so on. Lithium is different, although lithium is equipped with a protective plate, but the protection effect is not very good.
Compared with other motorcycle trams, Harley battery reliability and durability have a good guarantee. It can be used for more than three years under proper and reasonable use and maintenance. The Harley battery has the following advantages:
1, the battery electrode design is reasonable, the electrode screw fastening surface is flush with the battery side, can properly tighten the starting motor line, without adding gaskets. Avoid bad contact.
2, the battery is AGM type, that is, the battery using pure sulfuric acid solution as the electrolyte. The cyclic charging capacity is 3 times higher than the traditional storage battery. Also maintenance-free (refers to supplementary electrolyte type).
3. The charging circuit of the Harley motorcyclec is designed for AGM batteries, and the matching degree is higher than other types of batteries.

The technology-intensive metal stamping dies have gradually emerged as a high-end, large-scale, sophisticated and sophisticated development trend. It is one of the rapidly developing industries in the domestic mold production field in recent years, and has become an important force to promote China to become a mold manufacturing powerhouse.
At present, the development characteristics of the domestic metal stamping die industry are obvious. Large-scale, sophisticated and complex products have become the mainstream of the industry. The technical content will continue to increase, and the manufacturing cycle will continue to shorten. The production of stamping parts processing molds will continue to move towards informatization, digitization, refinement, and high speed. With the development of automation and automation, the comprehensive strength and core competitiveness of the industry have increased significantly.
It is reported that the hardware domestic stamping die industry is continuously catching up with the world advanced level and continuously narrowing the technological gap with developed countries. Many domestic precision stamping dies have been able to compare with imported products in terms of main performance, and the overall level of the industry has been significantly improved, not only importing Instead, there are a considerable number of exports to the United States, Japan and other industrialized countries and regions. At present, China's precision stamping dies are actively going to the international stage and participating in international competition. Although there is still a certain gap between the developed countries and the developed countries, according to the current development of the domestic industry, in the next few years, the domestic stamping die industry will surely catch up, become the backbone of the development of the domestic mold industry, improve the industry's overall level of technology, To promote the domestic mold industry toward high-end, precision, large-scale, complex development.
