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.

Customization capabilityThe supplier provides 3D software design services and reports customization from samples, designs, flexible customization, minor customization, and full customization. These statements directly support broad product and design customization capability.

Product Q&A

Q:How do I judge what material my battery is?

Please take a look at the battery body. If the normal voltage shows 3.2V, it is LiFePo4. If 3.6V or 3.7V, it is Li-ion or Li-polymer. You can also ask the manufacturer.

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

Check two questions: How many cells in series does your battery pack have? The board must match the series count. What material is your battery? LiFePo4 has different parameters, so inform us if buying for LiFePo4.

Q:Do we need cell balance or not?

Yes, balance is needed because cells in parallel and series cannot be identical. Without balance, cell voltages will become inconsistent after charging.

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

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

Q:What is your term of payment?

We accept PayPal, T/T, L/C, and Western Union.
