Shipping of DM Devices with regard to Batteries

Our devices rely different types of Lithium Batteries:

  • Lithium Metal batteries (like LTC or LiFeS2) for the battery powered devices like the Oyster2 or Remora2
  • Rechargeable LiPo batteries for internal back up batteries on externally powered units such as the Dart2 or G62

Such batteries are usually subject to shipping regulations or restrictions.



This guide is generated using TNT/FedEx guidelines

Overview/Rules of Thumb

  • There are limits to how many batteries can be shipped via road or air without being declared - i.e. usually a few devices with batteries contained within¬†(lithium ion batteries contained in equipment) can be shipped via air undeclared
  • Batteries on their own, or in large quantities generally need to go via Road. As long as the batteries are declared this doesn't need to travel as 'Dangerous Goods' - which is really a similar service but more expensive
  • Longer road transit times needs to be factored into the equation when providing devices
  • Potential 'dangerous goods' charges need to be factored in, but are often not applicable
  • Shipments must be properly labelled

Calculating Shipping Classification

Generally, shipping batteries in large quantities will automatically qualify that shipment as dangerous goods. If you're shipping batteries by themselves the shipment can not be shipped without declaring them.

If you are shipping batteries, Lithium Ion or Lithium Metal installed in, or packed with their devices, you can then consult the below table. Please note the Green squares mean you can ship via normal freight (at least with TNT) and the red squares mean you'll need to ship using a dangerous goods declaration. If in doubt, ship using road express.

How many is 5kg worth of Batteries?


If the total weight of lithium batteries for devices is over 5Kg, you cannot ship by Air and it must be booked in as Dangerous goods via Road.


Example 1: Shipping 75 Remora2 with Batteries installed in devices

75 Remora2s will take 150 batteries, with each battery weighing 110gs, this makes the total weight of the lithium batteries to be 16.5Kgs. This shipment will need to be shipped as Dangerous goods UN3091 via road freight.

Example 2: Shipping 10 Dart2s

10 Darts will have their lithium Ion darts enclosed, each battery weighs 5gs making the total weight of lithium batteries to be 50g. You can ship this in one box via Air without dangerous goods shipping or labels. If you use more than one box to ship you'll need to include the UN3481 label.

Example 3: Shipping 3 Oyster2s with Batteries packaged with devices

3 Oyster2s will take 9 LTC batteries weighing 20g each, bringing the total weight of lithium batteries to 180g. You can ship this via normal air freight with the UN3091 label on the box. be sure to pack the batteries inside a rigid box that prevents them from being moved around/bumped/crushed.
