What you basically need to consider when shipping and transporting lithium cells and lithium batteries is the following:
Every lithium cell and every lithium battery must be manufactured according to the quality management program described in the transport regulations, including prototypes and small production runs.
What this quality management program includes, you can find here:

Every lithium cell or lithium battery that is no longer a prototype or a small series of up to 100 pieces must have successfully passed the UN test series 38.3.
Since 01. January 2020 a UN 38.3 Test Summary needs to be provided by the manufacturer and any subsequent supplier on request. We have included all required details of the UN 38.3 Test Summary in our Supplier Inquiry Form.
Our supplier inquiry form helps you to get all necessary information for logistics. You´ll find it here:

And the following technical requirements have to be fulfilled for large lithium ion batteries:

- Each lithium ion battery incorporates a safety venting device or is designed to preclude a violent rupture under normal safety conditions.

- Each lithium ion battery is equipped with an effective means of preventing external short circuits. 

- Each lithium ion battery containing cells or series of cells connected in parallel must be equipped with effective means as necessary to prevent dangerous reverse current flow (e.g. diodes, fuses etc.).
We support you in making all preparations for shipping in compliance with the regulations. If you have any questions, please feel free to contact us:
