Amass connector — LC series of products with the European Union environmental protection standard lead content <1000PPM, temperature rise <40℃, eliminate instantaneous break and other eight product characteristics, give UAV, electric vehicle, garden tools and other lithium electric equipment a new product experience. In order to meet the needs of intelligent devices for high-current connectors, LC series adopts copper conductor, compared with XT series brass conductor, current carrying performance is greatly improved; 360° crown spring contact structure, not only the insertion and extraction life is long, but also effectively prevent the insertion and extraction of instant break.
