I haven’t done the math, how much runtime could you get out of a single 18650? They’re pretty stout, but it seems like they’d be a bit underpowered.
Milwaukee 12v batteries are 3 cells (I think they’re a little smaller than 18650), and you can run through a battery pretty quick (I believe they’re 1.5AH). Though I don’t know how efficient their heating design is.
Assuming the M12 CP1.5 battery pack, it’s probably three 18650s. Specifically, it’s probably three LG HB series 18650s, which handle high burst loads well, but hold only 1500 mAh. A single Sony VTC6 holds 2/3 the energy of one of those packs. Wait… why am I speculating? Youtubers tear down power tool battery packs on video all the time, and someone did that one. They’re Samsung 15Ms, which are a little worse than HBs.
Anyway, short runtimes are fine for most field repairs, which is the whole point of something entirely self-contained. Spare batteries can extend it indefinitely, but a battery soldering iron is probably not what I’d pick for extended soldering sessions.
