What Documents Should Overseas Buyers Request from a Lithium Battery Supplier?
Direct Answer
Overseas buyers should request a battery specification sheet, model and certification scope, BMS function description, factory test records, label and packaging information, user manual, warranty boundary, and shipment-related documents. For custom packs, final specifications should be confirmed in a mutually approved project specification.
Key Takeaways
- Documents are part of supplier evaluation, not only shipment paperwork.
- Certification must match product model, specification, and target market.
- Factory test records help buyers review batch consistency.
- Custom specifications should be confirmed before sample and mass production.
Document checklist
| Document | Why it matters |
|---|---|
| Battery specification sheet | Confirms voltage, capacity, Wh, dimensions, connector, charge/discharge limits, and use conditions |
| Certification evidence | Shows model scope, standard, applicant/manufacturer, issue date, and validity |
| BMS function description | Explains over-voltage, under-voltage, over-current, short-circuit, temperature, balancing, and communication strategy |
| Factory test checklist | Supports quality review for capacity, insulation, sealing, appearance, BMS, and traceability |
| Label and packaging plan | Supports channel, compliance, storage, transport, and after-sales identification |
| Warranty boundary | Clarifies proper use, excluded conditions, service process, and evidence requirements |
Certification caution
A certificate is useful only when the model, product name, specification, and standard match the product being purchased. Custom models may require separate scope confirmation.
Buyer recommendation
Build a document checklist before ordering samples. This reduces the risk of selecting a pack that performs well technically but lacks the documents needed for market entry or channel approval.
FAQ
Is one certificate enough for every custom model?
No. Buyers should confirm whether the exact model and specification are included in the certificate scope.
