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 do I judge what material my battery is?

Check the battery body voltage: 3.2V indicates LiFePo4, while 3.6V or 3.7V indicates Li-ion or Li-polymer. You can also ask the battery manufacturer.

Q:Can I use this protection circuit board for my battery?

Ensure the number of series cells matches your battery pack. Also, specify if you need it for LiFePo4, as it has different electric parameters than other batteries.

Q:Do we need cell balance or not?

Yes, balance is necessary because cells in parallel and series cannot be identical. Grouping cells with similar performance without balance may lead to issues.

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

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

Q:What are the charging and discharging current limits?

The maximum continuous charging current is 200A, and the maximum continuous discharging current is also 200A.
