How do you match cells for a battery pack before assembling?

We select same capacity cells, measure voltage (difference under 0.02v per cell), and measure inner resistance (difference under 1m Ohm) to ensure perfect pack performance.

What is your advantage compared with other suppliers?

We offer high quality batteries with enough capacity and lower RI, strict inspection before shipment, and better service including timely replies and best project solutions.

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.
