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 determine the material of my battery?

Check the battery body voltage. If it is 3.2V, it is LiFePo4. If it is 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?

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

Q:Do we need cell balance function?

Yes, because cells in parallel and series cannot be identical. Without balance, voltage inconsistency occurs after charging, affecting performance.

Q:What is the Minimum Order Quantity (MOQ)?

We do not have an MOQ. We provide various capacities and sizes per your requirements, and OEM/ODM is welcome.

Q:What are the payment terms?

We accept PayPal, T/T, L/C, and Western Union. These methods can meet your requirements for various battery pack types.
