I know that this question should be posted elsewhere but I figured that I would get an answer here quicker. I just got my first Kanger Subtank Mini and I would like to know (since I am new to this) how to build a coil for the rba that came with it to have a 1 Ohm or slightly higher resistance. I also have not found any information about using this coil with the tank. Does it work just like the OCC's that came with it? I ask this because the RBA does not have the large holes like the OCC's do. I did find several vids on YouTube about how to build coils and also how to rebuild the OCC's but nothing was specific to building a coil for the RBA so that I can use it with my Vamo V7 mod which is rated down to only 0.8 Ohms. Thanks in advance for any help on this subject.
