Have we chosen a sacrificial dripper yet? We all know first ones gonna expire in short order choose one Rags that'll be my contribution
I think with a larger atty (you can buy 32mm ones?) with heavy kanthal perhaps 0.5 or 0.6 mm and a shit-load of winds on a dual coil setup to bring it to around 2 ohms your going to get wicked performance!
Actually sod it, just worked out this theoretical build... soo much coil to wick contact <dribbles>
dual coil
0.5mm kanthal
3mm inner diameter
32 wraps each coil!!
@100 watts it only equals 157mw/mm2 heat flux... thats stone cold, you could push 150 watts through that easy :-) :-)
Problem is you need to push 15 volts to hit 150 watts.... oops
Anyone fancy stacking 2 lipos?
Having melted the insulators in every one of my RDA's I've been able to get the Zenith running with its own insulator, the Mephisto repaired with an insulator bodged from a crappy 3D that wasn't getting used and the Origen clone with a piece of thick card. Since swapping to 8.4V though, I've been able to wind coils at way higher resistances(from 0.1x to 1.5+ ohms)and this has produced as good clouds without needing to drill wider holes for airflow and the vapour isn't hot at all. I did try lowering the resistance to sub-ohm at 8.4V, but anything under 0.7 ohms was just too hot to take more than mini - inhales even with 3 holes right over the single coil. My present build is about the 50 watt area, and is really strong flavoured(I'd increased the flavouring a couple percent to compensate for the extra airflow at -0.2 ohms)
I expect Raguri will still want to sub-ohm, though why he would need to at 8.4V escapes me
As gords1001 said though, I to reckon that 4.2v currents are killing the insulator.
