Hi everyone,
Here is one question that i am curious of. I am using Vaporesso Revenger mod with nautilus 2 mini ato (with 1.8 Ohm coil). Vaping MTL style at 4.xx volts (12 Watt). On the coil it says safe vaping levels are between 4.2 - 5.0 Volts.
But in some articles i read that above 3.7 volts, it is so risky to vape. Is it true? Or is it about rebuildable coils? I am a bit confused. What should the voltage be with nautilus 2 bvc coils when MTL?
Thanks in advance
One thing you are not taking into account, Katya explained a bit, but with most current mods voltage needed to get to set watts is calculated by the mod itself. Now your concern of 4.6v being asked from a 4.2v highest charge battery and lower voltage after that once the charge decreases due to use is not a real concern. You have 2 voltage circuits in a regulated mod, batteries > control board *most important* and control board > atomizer/tank *not really important information and is the voltage most mods display when firing*. Current control boards in the control board > atomizer voltage signal can either "Boost or amplify* the voltage from the batteries when voltage needed is higher than voltage supply (from the batteries themselves), and the second method is to "Buck or Shunt" voltage down when needed voltage is lower than that of the voltage supply from the batteries then the voltage is bucked down. What you are seeing displayed is the voltage being bucked down given your mod is a dual battery series battery configuration, in this configuration the voltage supply is voltage of single battery X number of batteries the mod uses, dual battery this becomes 4.2v highest X 2 = 8.4v supply, not 4.2v or the median rating of 3.7v, even then 3.7v X 2 batteries is 7.4v supply, CDR amp rating and Mah or a single battery ratings are still the same of a single battery in this configuration.
So the voltage from the control board to the atomizer/tank is not really valuable information unless you are using that display coupled with the ohms of your atomizer/tank coil and using an Ohms Law formula to check accuracy of your set watts. The biggest safety rating of batteries we can not go above is the CDR amp rating, or Continuous Discharge Rating of how much current we are requesting rated in "amps". This is another formula subset of Ohms Law, for a regulated mod we use the Watts Set, divided by the lowest possible voltage available before a check battery error, low battery error, or complete mod shutdown.
Voltages of 18650 batteries on most current mods is 3.2v lowest (before error or shutdown) and 4.2v highest fresh charge, we need only that 3.2v figure, being your mod is a dual battery series, we get 3.2v X 2 = 6.4v <- We use that figure in our calculation.
12watts/6.4v=1.875amps. To add more accuracy we can divide this by 90% for the control board efficiency (how much power the board itself takes to operate and function)
12watts/6.4v/90% or 0.9=2.0833 amps needed from the batteries. Most suggested batteries in vaping, the CDR suggested is 20amps minimum, 2.08 rounded up is about 2.1, so 2.1 of 20 you are only about 10% what the battery is capable of, and well within the safety capabilities of the batteries.
Even on a single battery mod
12watts/3.2v/.9=4.1667amps ever needed.
