We have several engineers with more than ten years of professional experience in lithium battery R&D and design and protection board development. They have their own technical ideas in the development and design of power batteries, high-voltage batteries, wide temperature range batteries, and 18650 battery pack assembly design. We help many customers at home and abroad to solve the needs of batteries for multiple purposes.We use domestic and foreign quality-guaranteed lithium battery material suppliers as suppliers, and have cooperated with them in a number of new materials fields, and have made significant progress in the development and commercial application of silicon carbon anode and graphene materials. We strictly control the quality of the battery cells, adopt a scientific and reasonable assembly method that pays attention to details, and exerts the battery performance on the basis of fully ensuring the battery quality
