More power (literally) for the HP-41, follow-up.

Transportation rules are under the UN 38.3 regulation.

The tests required :

With a cell INSIDE a device you need to follow that regulation :
Classe 9 – UN3481
with a mandatory label onto the parcel (you need to buy the official labels)

and OUTSIDE (or standalone) :
Classe 9 – UN3480
Not sure you can fly them anymore .... or via cargo plane only.

Basic rule (check the exact figure) : Never transport the cell fully charged, 30-50% Max of SOC. It will thus contain less energy, just in case...

You need to check the exact transport rules with your transport company and it may depend on the country IN/OUT.

Maybe a good solution would be to let people buy the pouch on Ally express or whatever supplier you have chosen. And deliver only the pack itself ?
Personally i would be interrested into the components BOM and boards CAD files, so i can build it by myself... I had such project but not enough time at moment.
