AI-Powered supplier vetting

SummaryHUNAN CTS TECHNOLOGY CO., LTD. is identified as a factory-type, combined company in Changsha, China, with business activities covering battery manufacturing, battery-part production, electronic products, photovoltaic equipment, and related technology services. It reports production capacity of 500,000 EV batteries and 100,000 ESS batteries annually, two quality inspectors, standardized finished-product inspection instructions, and design customization from samples and designs. The supplier provides ODM and OEM services, including for well-known brands, but reported no new products in the past year and no available SDK. Service procedures, complaint handling, and corrective-action records are documented. It has in-stock capability but no overseas warehouse or showroom, and no valid manufacturing-capacity contract with its factory and affiliated subcontractors. Trade evidence is limited to one recorded transaction, with the supplier registered in March 2025.

Supplier typeThe supplier is described as a factory and a combined company located in Changsha, with stated battery manufacturing and battery-part production activities. Its business scope also includes technology development, electronic products, photovoltaic equipment, and import/export agency, while trade records identify it as HUNAN CTS TECHNOLOGY CO., LTD., registered in March 2025.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints. However, it has no overseas warehouse or showroom, while its stated in-stock capability and lead times within 15 working days provide some fulfillment support.

R&D capabilityThe supplier reports no new products during the past year and no available SDK, which are explicit limitations. It does have stated technology research, software development, and resource-recycling technology activities, but these do not establish successful recent product innovation.

Production capacityThe supplier reports annual productivity of 500,000 EV batteries and 100,000 ESS batteries, two quality inspectors, standardized finished-product inspection instructions, and battery manufacturing in its business scope. Nevertheless, it reports no valid contract covering the factory and affiliated subcontractors, creating a documented production-governance weakness.

Customization capabilityThe supplier explicitly offers customization from samples and designs, as well as ODM services, and reports OEM service for well-known brands. These statements directly support both product-design customization and outsourced design/manufacturing capability.

Client casesThe supplier states that it provides OEM services for well-known brands, and the trade record names L CHARGE HOLDING INC as an associated buyer. However, only one trade transaction is recorded, so the available customer-case evidence is limited.
