Hello, i am pretty new to sub ohms and VW - VV, i have bought Cloupor mini 30 W box mod and Aspire Atlantis and i am using Samsung ICR 18650 26F 3.7 V ... I am pretty happy with this batteries (have been using them since i first bought ordinary mod)...Cloupor has screen and it shows volts, ohms, remaining battery etc. This little box is VW. When i have 22,5 W it says 3,7 Volts, but when i change it to 25 W it is saying that my voltage is 3,92...Sorry if that is something obvious, i have just been curious because i thought that when battery is 3,7 V it should be 3,7 V everytime independently of Watts...Isnt it dangerous? Thanks
