What to look at for this product
If your door lithium battery pack powers a cordless pet door, request the transport test summary matching the main or backup pack you supply.
If your pack is boxed separately from the door, check the lithium battery marking planned for that battery's shipping box with your supplier.
If your pack travels alone by air, ask how the carrier applies the passenger aircraft ban to the door's separate battery shipment.
If your pack is boxed with a pet door for air shipment, check the charge restriction applying to the door and battery package.
If your pack comes with transport testing records, request the completed test results identifying the battery cells and the assembled power module for that door.
If your pack is sent by cargo aircraft without the door, ask the shipper which charge limit applies to the supplied door battery.
