For OEM battery buyers, good communication is not enough. LiFePO4 battery pack quality should be supported by documents that show how the supplier controls cells, assembly, BMS settings, aging, and final inspection. Requesting the right documents before shipment reduces disputes and helps distributors handle customer questions.
Core documents to request
Ask for cell matching records, BMS parameter sheet, charge-discharge test report, capacity test, insulation test, aging record, appearance inspection, wiring diagram, label confirmation, and packing list. For regulated markets, confirm certification requirements before sampling, not after mass production.
Use documents to compare suppliers
A professional supplier should explain test conditions clearly. Capacity, cycle life, and discharge current are only meaningful when the temperature, cutoff voltage, and test rate are stated.
