Just reporting that my @thefreeman’s 4.5V “long” adapter worked perfectly for flashing my new FireFlyLite T9R with SBT90.2 LED (my first and so far only light from FFL) as well as all the rest of my Anduril collection (flashed them all yesterday with TK’s latest 2024-04-20 plus my custom configurations and mods) with absolutely no issues.
Thanks again @thefreeman for that great adapter!
