Here is my set-up right now. Bolt(3.7v) with the extension so I can run 18650. I have two 18650 battery's and one 18500 battery's(I know I'll need more battery's). I have a Vivi Nova tank that I rebuild and soon I'll have a mini "DID" clone. but wut more should I have? A USB passthrough(can I use them on a car lighter adapter?)? Please help me!!!
