Heatable clothing with lithium cells or lithium batteries

It's getting cold and during outdoor activities some people like to have heatable clothing. There are many models with rechargeable battery packs. The lithium cells and lithium batteries are often interchangeable so that you don't have to suddenly freeze when the performance drops.
If you are thinking about buying heatable clothing, you are well advised to make sure that the lithium ion batteries also meet all regulations. 
The lithium ion battery must:

1. be manufactured under a well-defined quality management system (e.g. ISO 9001 manufacturing would be sufficient); and
2. the lithium ion battery must have passed the UN test series according to 38.3.

Here is the link to one of the many tests around clothing and equipment:

Because no matter how nice warm hands and feet are during outdoor activities, you don't want the lithium-ion battery to catch fire while being charged or worn because the manufacturer has not followed the technical requirements.
We offer you a free supplier inquiry, which you can have filled out by the dealer/manufacturer of the lithium ion battery and thus ensure that all requirements are met. You can download it under the following link:
If you are wondering what the UN test series after 38.3 is all about, you will find the answer in our Lithium Battery Service Portal at:
