Still need to proof it durability but the material used showed it strenght.
Allow you to use your e-mag electronic by replacing the front battery by a special block that is powered from a wall plug(charger?). Featuring energy regulator to allow it to use the current from the wall. The concept make you save your battery because when you are on the field you dont want a dead battery(And yes we know that you can still switch the selector switch to mechanical only But you all know that the hydrid mod is awsome!). This wonderfull design is best suited to any airsmith that work with agd e-mag/x-mag/sfl... or any other people that like to tune their e-mags.
