Winblows, Regulated mods will give you the vape you want in a much safer way. They all cut off and declare the battery "empty" at 2.9v to 3.2v for safety and increased battery life. In addition to that they provide short protection and some have over-temp protection. A regulated mod also provides a wattage mode that automatically sets the right voltage to the coil to create the wattage you set.
Mechs are considered cool these days because they are retro devices. They don't offer any benefit other than that and you miss out on many features that are desirable. Temperature control and variable wattage are nice functions to have. You also get a display that shows you what's going on in the mod in terms of remaining battery capacity, coil resistance, and current wattage and temperature.
It's much better for your
batteries if you don't subject them to stress by over-discharging them. You can find out what
batteries are best by visiting Mooch's blog where he has rated
batteries in the 20A to 25A range for use in regulated mods.
