The first picture shows the fpv items I received.  The display was by itself in a box that was opened, the bracket and antenna were each in their own plastic bag, and the one bracket screw was loose in the quad's box. (I didn't find any empty plastic bag or the other screw)  The second picture is a closeup of the one screw I received.  It measures 23.2mm long, and the shaft is a total of13.8mm long and is 2.93mm wide.  I don't know offhand what the thread pitch is but I could probably figure it out if you need it. (it's pretty fine)  The charger you linked me to only does two of these batteries at a time.  I'm looking on ebay now and there are a number listings for 1200mAh batteries in this size. (I wonder if they are misrepresenting capacity?)  Finding a balanced charger for batteries with the larger red connectors is harder, but there are some that use the smaller white connector on the charger with adapter cables.
