When lithium battery is ?gpacked with?h equipment, the dangerous goods is the Lithium Battery, and the ?gequipment without the battery?h is not dangerous.
Imagine an OVERPACK. The dangerous ?gLithium Battery?h is packed in one UN specification packaging. Now you pack the non-dangerous ?gequipment?h in a Sep rate ordinary outer packaging. You put the two packages into one OVERPACK. This is the concept of PI 966.
Therefore you have 2 choices. First choice is to pack the Lithium Battery in a PG II certified UN specification package. You pack the ?gequipment?h in one ordinary package. You put the two together in one bigger outer packaging which serves as an OVERPACK.
The second choice is to pack the lithium battery in one inner package. You pack the equipment in another inner package. You then pack the two inner packages into one UN certified PG II outer packaging.
