My thoughts are, voltage drop has become an obsession with mechanical
mod users; and contrary to popular opinion, the main cause of drop is not due to the tube material. It's primarily due to the battery. No two
batteries will perform exactly the same, even if they are the same brand, and the difference in performance will be more significant than the material of the
mod tube.
