  • There was this company doing something similar with CDs. They sold the physical medium and then let you download the ripped files and store the CDs at their place. In fact, you could just buy the record online and directly download a .flac from their website. And if you wanted, you could have the physical medium shipped to you.

    Apparently that was legal, but they have gone bankrupt a few years ago iirc. They were called Murphies (idk about the spelling).







  • There are, but to use them as a replacement for NiMH/Alkaline cells, they need voltage conversion and typically have a built in charging circuit so you can charge then via USB-C for example. Theyre expensive, have a similar capacity compared to NiMH and can’t be charged in a regular battery charger.

    On an other note, there are 1.5V lithium batteries (non-rechargable). They supposedly have a higher capacity and last longer.

    And then there are 14500 Li-Ion cells that are about the size of an AA cell but run at 3.6V.
