Elimination of mechanical contacts solves the problem of their gradual wear. MOSFET transistors utilized in Perun V2 have a much lower resistance than contacts, which increases rate of fire. Small elements in the trigger mechanism responsible for semi-automatic fire frequently malfunction, especially in replicas built on parts made by many different manufacturers.
Programming of all of the settings, not only firing modes but also switching active brake and battery protection on and off is done only by using easily memorable fire selector and trigger sequences. That allows changing the settings at any moment in a matter of seconds, even under enemy fire.
Batter protection mode is dedicated to Li-Po batteries. Should the battery voltage fall to a dangerously low level, user will be notified by short sound signals repeated every 30 seconds. This may also be freely switched on and off.
