Presenting for your pleasure the production Pandora battery; layered wafers of lithium in a ruffled German wrap, and the subtlest hint of rich creamery butter. The reason for the slightly ruffled look isn’t clear just yet, but we’ll be watching this space for answers and dutifully reporting back. Some say it contains chocolate. In any case, it’s a delicious pic and another step down the home straight.

Update: Scenester j.pickens has pointed out that soft wrappings similar to this are used on RC car/plane batteries. This allows the battery to expand and contract ever so slightly, which maximises the capacity. Still no official word on this, but it does make a lot of sense.

  1. lol! xD


  2. isn’t that a papercraft one from yesterday?


  3. Yummy!


  4. It doesn’t contain Pb – that’s peanut butter, right?


  5. I liked it better before the logo was plastered all over it, but whatever.


  6. Is that a photo? Or did they just put it down on a scanner?


  7. Mmmmmmm, Chocolate and Lithium…

    (And I’m sure it’s all those lethal peanut allergies that keep them from putting in the Pb)


  8. A chocolate/candy bar with that envelope would be a real treat😛.


  9. Even if it’s one of the last thing that matters from a design pov, cool🙂


  10. I would be scared to use that battery. It looks like it would be ready to explode at any given moment.

    Cheap Chinese Battery?


  11. I hope mine has a golden ticket!


  12. for those who isnt is joking about when they ask what Pb means it means lid(plumbum, the metal, hope I spelled it correctly). No technology ordinary people can buy contains plumbum nowadays, so dont worry.


  13. It IS the golden ticketo_O

    the ticket to hours and hours of use on the pandora! =D


  14. Lithium cells which don’t have a reinforcing molded plastic shell look like this. The cells are in a flexible enclosure to allow them to expand and contract. By skipping the outer shell, you maximize the capacity of the battery in the space allotted.

    Radio Controlled airplanes and cars have unenclosed packs like this.

    Examples:


  15. Thanks j.pickens, I’ll update the post.🙂


  16. For those that aren’t familiar with their Latin
    plumblum == lead


  17. Latin or no Latin (It’s on the periodic table, after all) I don’t think anyone seriously believed that there was peanutbutter in the battery.

    Serious question : How does it maintain contact if it’s flexing slightly? Airplane batteries typically have leads coming off them.


  18. That’s a good question, but we don’t yet know if the RC battery comparison is correct. If anyone official is reading, your word would be golden.


  19. Previous vids of the Pandora showed that the contacts from the unit to the battery were spring loaded somewhat to maintain contact even with a bit of flex. Most cellphone batteries use a similar method.
