AI-Powered supplier vetting

SummaryThe supplier presents itself as a Battery BMS manufacturer with documented quality, service, R&D, and production processes. It reports OEM and ODM services, SDK availability, 3D design, broad customization, recent new-product activity, and documented design and verification records. Production-related evidence includes SMT, screen printing, reflow soldering, AOI, coating, drying, packaging, and dedicated testing equipment, with standardized finished-product inspection instructions. It has participated in several offline trade shows and identifies Shenzhen and Hong Kong ports as nearby logistics points. However, the provided information does not establish certifications, named customer cases, or financial performance; it also reports no overseas warehouses, showrooms, agents, or branches.

Supplier typeThe supplier identifies itself as an active Battery BMS manufacturer and reports both OEM services for well-known brands and ODM services. This supports classification as a BMS manufacturer with contract design and manufacturing capabilities.

After-Sales capabilityThe supplier reports clear procedures and followed records for corrective and preventive actions and customer complaint handling. Its technology engineers also provide technical support for production and after-sales service, indicating documented and technically supported after-sales processes.

R&D capabilityR&D engineers handle customer-request confirmation, technical support, and new-product development; design input, output, review, verification, and validation documents are reportedly available for audit. The supplier also reports new products within the past year, ODM capability, and SDK availability, providing explicit evidence of active R&D capability.

Production capacityThe supplier reports multiple manufacturing and testing facilities, including SMT, screen printing, reflow soldering, AOI, coating, drying, packaging, and dedicated power-protection-board testing equipment. It also states that finished-product inspection instructions are available and uniformly followed, while quality assurance and written supplier-service assessment procedures are reported.

Product Q&A

Q:How many Ampere protection circuit boards should I choose?

It depends on your load power such as electric motor power. Please contact the sales or technical support before buying.

Q:What is the distinction between same port wiring and different port wiring?

For different port wiring, the cathode of charger and load is different. For same port wiring, the cathode of charger and load is the same, and the charging current equals the discharge current.

Q:What is the distinction between balance and unbalance function?

The equilibrium function discharges high voltage cells with a resistor to wait for low voltage cells, achieving consistent cell voltage to improve the battery performance for the whole group.

Q:Do you have a Minimum Order Requirement (MOQ)?

No, we do not have MOQ. Different customers have different requirements. We can provide various capacities and sizes per your requirements, and ODM/OEM is welcome.

Q:What is your term of payment?

We accept PayPal, T/T, and L/C. For any further questions, please contact our sales person by sending an inquiry.
