Greetings to you all. My first post on this site. Loads of great info here. There’s lots on this site to keep someone busy for a long while. I’ve been reading a lot of posts regarding thermal vision scopes. I just purchased a new Armasight 640 2-16 50mm and hope to get some good use out of it. I joined to hopefully get some information on the Armasight extended Battery pack. I’ve read as many posts as I can and I’m in the process of building my own external battery pack. I’ve uncovered a lot of information here but need a little bit more. I’ve sourced the components and am now trying to find out which pins are positive and negative on the Binder plug coming out of the Armasight extended Battery pack. Would anyone have one of these Battery packs and be willing and able to test theirs and post a results?
