How many batteries can be transported in a single container?

The number of batteries that may be transported in a single container depends on several technical and regulatory factors:

  • Battery dimensions — physical size and geometry
  • Condition — e.g., like new, non-critical, defective, critically defective, or prototype
  • Packaging instructions — the applicable ADR/UN regulation (e.g., SV 376, P 911/LP 906)
  • Performance data — specifically watt-hours or rated energy
  • Cell chemistry — e.g., NMC, LFP, NCA
  • We offer transport containers in various materials, sizes, and configurations, so the permissible load varies depending on the model.

We offer transport containers in a variety of materials, sizes, and configurations, so the maximum load capacity varies depending on the model.

Here is a selection of two products from our portfolio:

The XS-Box 1 Basic for smaller lithium-ion batteries and devices containing lithium-ion batteries and cells, e.g., from smartphones, garden tools, vacuum cleaners, flashlights, measuring devices, etc., for which packaging instructions PI 903 (like new), PI 908 (defective), PI 909 (for recycling), and PI 910 (prototype) apply.

The M-Box X1 E is suitable for transporting multiple lithium-ion batteries from e-bikes, individual HV modules from e-mobility applications, stationary energy storage systems, and multiple smaller lithium-ion batteries from tools such as drills or angle grinders. Of particular note is its design for transporting critically defective lithium-ion batteries in accordance with Packaging Instruction PI 911. This makes the box especially suitable for applications where an increased risk potential must be taken into account.

Our product descriptions and data sheets specify the specific transport application for which each container is designed.

The required packing material is generally already included with our products. You can also find details on this in the product data sheets mentioned above.

What is the difference between PyroBubbles Premium and Pure M?

How do PyroBubbles Premium and Pure M differentiate?

PyroBubbles Premium and Pure M differ in composition, heat resistance, and particle size. The Premium grade is made from pure primary glass, is heat-resistant up to 1050°C, and has a particle size of 0.5–5.0. Premium can be used in fire classes A, B, D, and F.

The Premium grade is made from pure virgin glass, is heat-resistant up to 1050°C, and has a particle size of 0.5–5.0 mm. Premium is suitable for use in fire classes A, B, D, and F.

In contrast, Pure M is made from recycled glass, is heat-resistant up to approximately 900°C, and is available in grain sizes ranging from 2 to 4 mm. This granulate is suitable for use in fire class D.
