    Don't you think it is dangerous to charge a LION battary with 5.5 volts?

    Most cellphone batteries has a built in charge protection circuit. This one did and that's why I didn't add a separate charge module. It will disconnect by itself so it doesn't over charge/discharge 🙂

    It has 2 intensities, low and high. The idea was to save power with the low setting, as well as not waking up your roommate or something with the bright setting :-)
