Can you explain in detail how you match cells for a battery pack before you assembling the pack?

We will do the following things before assembling the pack: a. Select capacity, same capacities cells for one pack b. Measure the voltage, same voltage cells for one pack(difference is under 0.02v per cell) c. Measure the inner resistance,same IR cells for one pack (difference is under 1m Ohm) All above steps are very strict to make sure the pack performance is perfect.

What&rsquos your advantage compared with other suppliers?

a. High quality batteries: Our batteries are in enough capacity, and lower in RI, Before shipment, we will inspect the products and ensure the quality which are well approved by our clients. b. Better service: We always offer what our clients need. Reply client&rsquos questions timely. Supply best projects solution for clients. We ship out the products on time&hellip

AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing-sector trading company in Longhua District, with OEM support for well-known brands, SDK availability, and documented R&D processes. It reports substantial LiFePO4 and lipo battery output, exports to East Asia, Europe, Australia, North America, and domestic markets, and typically fulfills orders within 15 working days during peak season. Customization is offered across several levels, while after-sales handling has documented complaint procedures and corrective-action records. The supplier reports CE, UL, IEC62133, and RoHS certifications, but the provided information does not independently verify them. Innovation evidence is mixed: the supplier has two R&D engineers, two patents, and R&D documentation, but no new products were launched last year. Overseas service infrastructure is limited, with no overseas warehouses, showrooms, agents, or branches. No specific customer names or case studies are provided.

CertificationsThe company description states that its products obtained CE, UL, IEC62133, and RoHS certification. These certifications are explicitly claimed, although no certificate numbers, issuing bodies, or validity details are provided in the slices.

After-Sales capabilityThe supplier has documented procedures and records for complaint handling, service-capability assessment, and corrective/preventive actions, and it offers training as an overseas service. However, it has no overseas warehouses, showrooms, agents, or branches, and the overseas-service country count is stated as zero.

R&D capabilityThe supplier reports SDK availability, two R&D engineers, two patents, R&D design and customization responsibilities, and auditable design input/output, review, verification, and validation documents. Against this, it launched no new products in the past year, so the evidence supports established R&D capability but not recent product-launch activity.

Production capacityReported output is 16.5 million LiFePO4 battery pieces and 26.4 million lipo battery pieces, with peak-season fulfillment within 15 working days and off-season lead time stated as within 15 working days to one month. The supplier also serves multiple international markets, but its quality-control testing equipment count is stated as zero and the quality-assurance and traceability statuses are unknown.

Customization capabilityThe supplier provides OEM services for well-known brands and supports customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D engineers are specifically responsible for designing and customizing products according to customer needs, with supporting R&D documentation available for audit.
