Nice idea. You might want to include the Digi-Key part number of the connector that you used in this example. There are many styles of FFCs out there....

Thanks for your advice! I just included the part numbers.
Yes it's a really nice idea. About the last picture : step 9, what are the other components use to realize this assembly ? Which kind of material between crimp and battery ?
Thanks !

The material between crimp and battery is copper tape.

Thanks!

Ah yes, nice ! But it is expensive, isn't it ?
Can we buy this copper tape on this website ?
Thanks again & Happy new year !
