Packing and shipping

Packaging method

Each battery pack is in a separate anti-static or protective sleeve

Cells between foam or cardboard partitions to prevent movement and short circuits

Inner boxes for batch production of 40 cells (varies by order)

The outer packaging carton is made of high-strength double-layer corrugated cardboard

All cartons are marked with product model, voltage, capacity and safety labels

Optional customization

OEM identification or barcode label

Bulk pallets or shrink packs are available upon request

When transported by land or air, there are 15 boxes on each layer of the cardboard, stacked ≤ 5 layers. When transported by sea, there are 16 boxes on each layer of the cardboard, stacked ≤ 7 layers.

Shipment: The cell shall be shipped in 25-30% state-of-charge (SOC) or in accordance with customers' requirement. The voltage range for cell shipment is 3260-3320mV ( The specific range of shipment voltage is subject to the label) .The remaining capacity of the cell after shipment and before charging depends on the storage time and conditions.

Tip: The cell that has been unused for more than 3 months is recommended to be used after recharge.
