Welcome to ECF 
1. You have a great device there. I'm looking to buy one myself. The only reason I haven't bought it is because of its size (I guess we are on the same boat here
).
There is a quick solution though... get a 18350 tube and a few 18350 batteries and thats it! The mod will be much much shorter (my calculations bring it to about 100-110mm) and easily hidden in a pocket. Only disadvantage is that a 18350 doesn't last near as much as an 18650 BUT if the stock battery lasts you two days, you will use 1 or maybe 2 18350 per day which is nothing. When I'm at regular work, I go through 4 batts on a siglelei mini zmax (100mm) with a mini aerotank and it doesn't bother me. You seem to vape less so two batts maximum. Thats also the setup that I'm preparing for myself i.e. a evic supreme with a siam mod tube 18350. That coupled with a mini protank 3 or a mini areotank gives a very low profile.
2. About rebuilding aerotank coils... very easy. Get some kanthal a1 wire, some 3mm silica wick and you can rebuild those things in under 5 minutes for a single coil or 6-7 for a dual coil setup. Honestly, a well made single coil, is far better than those stock dual coils, less work to rebuild it, easier to dry burn it and cheaper (you're using less resistance wire
Good Luck
Regards
Tony
