Packaging and Shipping
Round sodium-ion batteries are shipped at an SOC of 20% to 30% of their nominal capacity or as per customer requirements. The remaining capacity before charging after shipping depends on storage conditions and storage time.
Each small box is configured with slots to hold 6 batteries. Each large box contains 1 small box, sealed and labeled. Each pallet is organized into 3 layers, with 6 large boxes on the 1st and 2nd layers, and 4 large boxes on the 3rd layer. The total maximum number of batteries per pallet is limited to 100.
