That driver is designed specifically for the Boruit D10 (probably works with most of the varieties of that light too, like Sofirn/77Outdoors D25), which takes an 18650.
So far, Anduril works with several ATTiny MCUs, which we’ve made work with Li-Ion chemistries. Cell size doesn’t really matter at that point, just design a smaller driver to fit the host. There’s not a whole lot of reason Anduril can’t fit on a 10mm driver besides space, which would allow for 10440 and even 10180 lights to run Anduril.
This thread has some information about the quest for AA Anduril support. To my understanding, there’s a prototype driver design being tested currently.
Yes, but I’m still waiting on a good 14/15mm 12v boost driver.
All the triple optics I’m aware of have a much larger diameter than makes any sense for a 14500 light.
