I think a 26650 version would be a better alternative to a dual battery. Could probably retain a similar form as the original sx mini.
My problem with that is battery sag SUCKS with one battery at higher wattage, even a 26650. Its a beautiful thing to see hitting the firing button at 100w on a dripper and the live battery meter reading barely moving, compared to hitting this on 60w and seeing it move over halfway down lol.
