One cell to control them all So after not being on this site for too long I have gone out and bought 3 lights in two days emisar d4, d1s and olight h2r nova, and I'm looking for a cell that would suit them all was thinking of Sony vtc6 but unsure of button top or flat and in the nova if I can get away without adding a magnet inside the tube? Not to concerned if the magnetic charger works with vtc6, open to any suggestions that will work in all three??
