Resolve the decision before selecting a model.
PI966 applies to UN3481 lithium-ion cells or batteries packed with equipment. Confirm Wh, quantity, SOC, separation, protection, packaging, marks, documents, route and operator under the current edition.
| First decision | UN classification and shipment form |
|---|---|
| Evidence | Exact model, Wh and UN38.3 traceability |
| Operational control | Packaging, trained personnel and carrier approval |
| Review cycle | Every rule edition, route or product change |
Practical review checklist
Confirm chemistry, UN number, battery/equipment relationship, Wh and condition.
Prevent short circuit, movement, damage and unintended activation under the applicable instruction.
Match test-summary, marks, labels and declaration to the actual model and consignment.
Recheck rule edition, route, country and carrier acceptance before booking.
What to request from a supplier
Ask for a model-specific specification, electrical and mechanical limits, BMS or interface definition, current test evidence, document list, sample plan and change-control route. Keep open items visible rather than replacing them with a generic promise.
