        That article you linked is utter trash, but it is correct about battery weight of a charged battery…technically…very technically…barely.

        Like, a 4,000 mah lithium battery fully charged should weigh about 30 picograms more than when dead.

        To put 30 picograms into perspective; a single 5 inch long human hair weighs around 0.04 grams. Well that’s 40,000,000,000 picograms.

          Haha, that’s fair I didn’t really vet the article as I’ve read about the concept and know it’s true (although as you point out only on a technical level).
