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.
Lol, I get it, I often start doing the math and realize “someone has already done this”.
Cool, thanks for the link. I already knew the little 12v batteries suck (though they work fine for the intended purpose, like impact driver or work light). I kill them with any other tool.
Yea, I was just thinking is the runtime reasonable enough that having spare batteries is a sufficient approach. Like you said, long runtime isn’t required, 15 minutes total runtime is probably more than enough (though that would be hell on battery life cycle).
Since I already have a slew of Milwaukee batteries, I’m trying to avoid things with 18650, except where form factor matters (like my flashlights). A Single Battery to Rule Them All (or at least most things).
