AA oversized and reduce the number of batteries (voltage) to its need. Electrical continuity is ensured preferably by two "Parisian fasteners" to position in both ends and to weld together. Electrical continuity can also be achieved by two conductive screws (3 to 3.5 mm in diameter, head thickness 2 mm) connected by an electrical conductor with a diameter close to 1 mm, the wire can be wound around the head of screws, see below welding at the tip of the screw. Check the electrical continuity and length of the false battery, which should be close to 50.5 mm (see video) /////////////////////// AA / AAA battery packs AAA batteries AAA batteries AAA batteries AAA batteries AAA batteries AAA batteries AAA batteries AAA batteries AAA batteries AAA batteries Electrical continuity is guaranteed by two "Parisian fasteners" to be positioned in both ends and welded together. at the tip of the screw.
