510 is such a weird number. Did they just take “420” and shuffle a one from the 2 over to the 4?
Nope - just like how an 18650 battery is 18mm in diameter, and 65.0mm long, a 510 battery threading is 5mm diameter, and 10 threads (per millimeter I think?)

I thought it was describing the geometry of the cartridge threading… maybe that’s a backronym tho?
