Ok, if I understand you, it sounds like two CR123a batteries would produce too much voltage and not enough current, which makes sense to me.
You added four 7135 chips, which put more current through the emitter, and I’m guessing, that required a better heat transfer method? Man I have lots to learn. I have a soldering iron but I’ve only used it for fixing wires, I’m going to look for a guide or youtube video before I short something out lol
