I have the black tesla 120 watt tc mod. Using an authentic cloud joy alien rda. I need advice on the best way to build good coils and best ways to wick. I also need to know if I can run a couple different sets of batteries So I can get thru the whole day. BTW my parallel coil is running at 2.5 ohms and 80 watts on 2 efest 18650 2500 mah 35 amp batteries
