x1 18650 battery.

Cable for 220v

-------------------------------------------------------------------------------

I use the led with all power of the battery because the led support 3.6 volt
but is but it can be dangerous because the current consumption requires a high current passage, so it is mandatory to use a copper cable for 220, otherwise it would fire.
