Hi so I have been vaping for right at about 4 years and have tried pretty much every type of vape out there. But the one avenue I have never gone down is building my own MOD so I decided to get my feet wet per say and went out and bought a DNA 30 board and the usb charging board. So now im just looking for any starting tips anyone could give as I am brand new to this side of vaping and have no clue where to proceed on my little project. Im wanting to do some type of lithium polymer battery other than an 18650 but really don't know what my options are my goal is to have an all day vape so im thinking at least 2400 MAH. I mainly run RDAs and RTAs with around 1.3 OHM coils. I want to build it in a box type enclosure but not sure what size I should go because I haven't made a battery decision and am not quite sure how to mount all the components in the case. Like I said I am brand new to the modding life so sorry if im coming off as a total noob just looking for a little direction. Thanks in advance
