Thanks by the way please... what is a mechanical mod?
Short answer...
No electronics (and their protections); direct path from battery to atomizer; stronger vaporization on a full battery but no control/adjustment of the voltage applied so it will fade as the battery charge drops.
Full attention must be paid to the resistance of the atomizer coil as that will determine the amp draw on the battery(s) and it can easily surpass the safe limits (lower res=higher amp draw).
And any sloppiness in building and installing the coil can produce a short, with a sudden unexpected increase in current draw.
Experience matters... like with handling a chainsaw, near your face.
Safety first...don't drink and Mech.
