I have built a box mod capable of 2s and 3s LiPo batteries. Depending on your coil and airflow if will hit pretty good at 12v also. Would anyone be interested in a production version of this? It would not have any electronics inside and you get the straight power of the LiPo battery. Definitely something for cloud chasers although the flavor is good on a 1.5 Ohm twisted and 12v.
