Supplier typeThe supplier is identified as a trading company in its basic information, while its business-entity classification also states "Trading Company,Manufacturer/Factory." It reports a factory in Guangdong/Shenzhen, production lines, quality-control staff, and product output, supporting a hybrid trading-and-manufacturing profile.

CertificationsThe company states that its products have passed CE, FCC, and PSE certifications, and reports BSCI and ISO 9001 supplier-management-system certifications. These are explicit certification claims, although the provided information does not include certificate numbers, validity dates, or issuing bodies.

R&D capabilityThe supplier reports a strong R&D team, engineers with more than 10 years of lithium-ion vehicle-battery R&D experience, and an Industry 4.0 intelligent manufacturing system.
