My axis m17 mini definitely needs a battery change during the day. I am currently using a vtc 5 in there and have a avocado 24 bottom air about .4 ohms on top. I guess wingsfan summed it up better than I did. The hcigar is a 50 dollar mod in a 200 skin. I like my asmodus wood a lot, it looks amazing, but it is still an asmodus mod. They do have the kodama, and if you want dual battery wood, I believe that may be the only option. Check the width though, not sure if 25mm tanks will hang on it. My silvanusa is only 22 mm. If you vape at 90 watts, you are gonna burn through both batteries and juice, just kinda the way it is. Also, the m17 mini is a DNA 75 device,
