When I first started I had no idea the Vaping was so big!....I went to My go to place for info....YouTube!....All of the Vids,and People like Rip Tripper,and East coast Lou,TiaVapes.(Huba,Huba!)....I only have two B/Ms in My area,so I made the rounds asking for dead batteries,ego type for parts to build with....One place gave Me two ego batteries that didn't fire,turned on but didn't connect....Back to Y/T and with a scribe fixed them both by pulling up the center pin,like on the Vid!.....Another place had a dead 20 watt Istick and the Guy just gave it to Me!....as before,Y/T to find out how to fix....The #5 torx bit was hard to find but I picked up a set at Harbor Freight and ripped that Puppy apart!....The pos wire was shorting and must of killed the battery....I put a efest 2500 mAh battery in it and fixed the wiring,it fired right up!...The batt was charged up before I soldered it in and it vaped for two days with a clearo on it!..Then it went into lock mode at the end of the charge,connected the usb but no go,won't charge,so apart again,placed in the charger with the brain hanging on by the wires,charged up and again it lasted for two days!....I didn't want to keep doing that,so I bought a Istick 30 watt and a Big Dripper and been have a ball building coils and such! Now I have a Caravella mech mod clone,a Sidewinder,an E-pipe both from Smoktech,a Nimbus RDA,a 454 RDA,and two octopus clones!..When I figger out how to upload Pics I will post My Lil'monsters!....I'm going to put the Brain from the 20 watter and two Sony vtc 4 batteries in to a cast aluminum box from England,call "BimBox"....It's 100.0 mm x 25.0 mm x 50.0 mm using the top part with the 510 in it with the folding adapter on it too!....Z
