Question: As the supplier of the lithium cells for many years, you certainly know what is the best heating foil to warm up the cells in cold weather. Is there any recommend product? Can you help us?
Answer: At GWL, we have already published information about this topic many years ago. However, there is no specific product we can recommend. Additionally, we do not have any detailed knowledge or references about the products that some of our customer are using.
Generally said, there are many various heating products available locally. You can see many products with different names available in local hardware supply channels and when searching on-line. There are different names to search: Heating elements. Mirror heating foil. Heating film. Floor heating wires and foils, etc.
In this case our answer is: search and see for yourself.
