Incoming Battery Cell Inspection and Sorting

Reliable battery PACK manufacturing starts before assembly—with incoming cell inspection and matching.
Filmed in our production workshop, this video features 3.2V 100Ah LiFePO4 cells and the preparation stage before battery PACK assembly.
Beyond nominal voltage and capacity, cell quality management also requires attention to:
• Complete records of cell specifications and batch information.
• Testing and matching criteria for capacity, voltage, and internal resistance.
• Links between cell identification and inspection and test records.
Cell consistency is an important foundation for PACK performance. A QR code provides an identification point, while complete test and batch records make traceability meaningful.
Evaluating cell quality means looking beyond the “A-grade” designation. Acceptance criteria, matching tolerances, and supporting test data also matter.
