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 of your battery shows as 3.2V, the battery will be LiFePo4. If the normal voltage of your battery shows as 3.6V or 3.7V, the battery will be Li-ion or Li-polymer battery. You can also ask the battery manufacturer the material of the battery.

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

There are 2 questions: How many cells in series is your battery pack? The protection circuit board you need to buy must have the same number of cells in series as your battery pack.

Q:What material is your battery?

Only the LiFePo4 battery has different electric parameters from other batteries. So if you need to buy the protection circuit board for LiFePo4 battery, please let us know first.

Q:Do we need cell balance or not?

The function of balance is necessary because batteries are made of many cells in parallel and in series. Since no two cells are exactly the same, they must be grouped with similar performance, which requires a balance function.

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

No, we don't have MOQ. Different customers have different requirements. We can provide various capacities and sizes as per your requirements. Also, ODM/OEM is welcome. Just tell us the relative voltage, cells, current, or equipment, and we will help recommend the most suitable products.
