    Nice intractable, as it reveals the tremendous secret of "how laptop batteries are made"?.

    One question: to my knowledge, all the elements of a bank (6 in your case) must be identical, otherwise they will charge at a different pace and could become harmful: any clue about that?

    a second question: any clue about why an element could get hot? is that element completely exhausted? (to be thrown in the garbage?)

    One suggestion: show in the video (or suggest in the subtitles) to mark with a merger polarities as tested, otherwise there be some confusion.

    Thx again for the intractable.
