Just a question or two, I have a lava tube vv, but use a DID 
rba.  I am very interested in getting a mech mod that can assure long life and can be repaired.  Excuse my ignorance, but I generally have my lavatube set at 3.7 volts, with my coil at 2.0 ohms.  Will the precise hit at 3.7 volts until battery dips below this level?  Will there be a waiting list for this product, or can I expect quick shipping.  Your product, btw, is just beautiful.  This certainly looks like a product that will go the distance.   My lavatube is starting to show wear and tear at 3 months.   I am thinking about the 18650, are the batts used imr or protected.Thanks for your input.
