Here is my first experience with a mech box. I vape regulated after some time with tube mods and really did not have a whole lot of interested in a mech box other than I had some of the parts laying around so it was a cheap and easy build. Its a 1550P dual parallel mosfet
mod, varitube 510, 1 amp charging board. I had to remove the lower right post to fit the battery's. The cells are hard wired in parallel with 16g copper stranded wire, volt meter, charger board and tack button with 22 gauge. I used epoxy to create a raised window over the volt meter, then gave it 5 coats with permanent marker to tint it. It worked very well, I used a damp cloth between coats too remove the left over ink from the surface. After 5 coats it is very dark smoked colored and unable to see in from the outside. When
mod is fired it lights up more than enough even in daylight. I have enjoyed it so far and it is worthy of being in my daily rotation.
