As for cartos in a tank system on your volt, you have two choices.
Smoktek makes Single Coil Cartos in LR (Low Resistance @ ~1.7ohms) specifically for the 808D thread connection. These will perform very well, despite LR coils burning hotter making your liquid usages ever so slightly higher, it will deliver a fairly warm and noticeably enhanced flavor note. I personally love it and can't go back to SR (Std. Resistance). The LR will use a bit of extra juice on your battery also.
The only concern, and it's not that bad if you stick with liquids with a PG content of 70% and above, I personally use 70/30 (Pink Spot Vapors) and have no issues with the tiny pre-punched hole in the carto.
I am going to be trying some 50/50 PG/VG blends in these cartos within the next few months, i'll try and report back.
Pros:
- It works decent
- Decent price
- Low Resistance delivering great vapor experience.
Cons:
- Possible issue with 50/50 VG on tiny pre-punched hole

808 Single Coil XL Tank Cartomizer for the SmokTank XL
Your other choice, I believe Smokeless Image is preparing to release an XL carto as well, if this is factual, I would only recommend buying from them. Their QC on their cartos is pretty decent and of 6 packs of cartos, I only had 2 flukes (individual, not box).
Now for tanks. A lot of sites sell the DCT Tanks as a package with a carto and drip-tip, while this sounds like a bargain, it really isn't... Now, while Smoktek sells just the tank tube with end caps on the site I linked you above you, however. They're a bit costly in my opinion. I want to save you money and help anyone as much as I can. So here's my lead on the best price for DCT Smoktek tanks.
Economic:
SMOKTech 510 Dual Coil Tank Tube
Baller:
Pro DCTank Tube
Yes, ordering from 2 different vendors, 2 different packages. However, if you want to pay $10 for a single tube and end caps, I won't stop ya lol.
Now, you have 2 choices and both choices are priced exactly the same. The 6ml DCT tube and the 3ml DCT tube. You need to ask yourself a few questions when purchasing this. "What do I want out of the tank?" "How often do I change between flavors?" "How streamlined do I want my setup to look?" and "How often do I vape?"
Once you answer those questions, the choice should be quite evident.
From my personal experience; I love the 6ml tank, my favorite juice is Grasshopper from Pink Spot Vapors and of the 12 different PSV flavors I have, this one gets most of the attention. So not having to refill my tank for a few days is great. I personally like the look of the 3ml tanks a bit better, however the amount of liquid the 6ml holds really makes these fat tanks look pretty cool with all the liquid swirling around in there.
Lastly, will also want to get a drip tip. I personally like the drip tip I showed on the tank right now, it just fits the design and lines better. The one to the right on the manual battery is my favorite for comfort, you're not wrapping your lips on such a large diameter, it was also purchased off of the MVS site. The pink drip tip on the far left is what came with my DCTs and I never liked this style of DT because you're forced to have that half cm of drip tip in your mouth, not really my liking, makes the vapor aim more towards the back of your palate, less flavor that way.
These are just the important bases covered about the DCT. The two things I haven't covered is DCT Tank precautions and then punching and slotting your cartomizers. Been writing this for an hour and I just woke up, so maybe i'll come back and fill you in on that stuff later if you're interested.
Actually, as for DCT precautions, here's my detailed experience with DCT tanks:
First time I ever bring the DCT out of the computer room and into the public... Thing starts to gurgle, first thing that comes to mind... Damnit, it's flooded. Yep, it was flooded. Spend about an hour in class cleaning it up and getting profusive leaking everywhere.
Finally get home, plan was to pull out carto, take out as much liquid of the carto as possible and empty tank, was half full, about 3ml.
Go to pull out carto from tank. Bottom cap pops off. 3ml of Pink Spot Vapor Grasshopper. In. My. Hand! I'm raging ...... off now.
Blow out as much liquid into the 30ml bottle, I swear at least 2ml was salvaged out of just the carto...
Pop carto back into the tank and then fill tank up halfway. Instant bubbles, carto is filling back up. Sounds good. Vapes decent so far.
Hopefully I solved the issue for now. ...... that I blew away around 2ml into napkins and then 3ml into the sink. Never had this issue for about a week of using this tank and carto.
Smoke Tech LR Carto and 6ml Tank.
Vaped about 1-2ml so far through the DCT since I posted. Was starting to have a very ever so slight dry atty/wick taste. I did a few dry pulls and saw a few bubbles. Kept doing it just barely enough to see the liquid almost colorize the visible filler material. Vaped and it was better.
To further avoid another repeat of my earlier experience in a couple hours when I leave for school (I haven't slept since my last post, above). I popped the drip tip off, and slid the tank up the carto just enough to vent the tank. Slid the tank back on and saw a very tiny bubble go up. Vaped it and it as just like it was when I first experienced the Smok Tech DCT and carto a few days ago!
Guess these tanks just need to be vented every ml or so, that's what i'll do from no on at least.
Sorry for the long read, but you'll learn a bit, hopefully. For your standard volt batteries, I recommend that you get the 3ml tanks. I can kill all three of my volt batteries within 6 hours, so to have a 6ml tank on there wouldn't justify anything. Plus, what are you to do while you wait for your battery to charge? I think this calls for a couple mins of contact cleaning and re-filling the tank. However, that's just me.
P.S. As far as changing flavors go with a tank, it's doable, however you will taste weirdness after a few swaps. I recommend buying at least 2 tanks to hold different flavors and a dedicated carto for each flavor. Gut one or two of your old cartos to turn them into atomizers for testing new flavors before you dedicate a new carto, please use these atties only on a manual battery. 4-5 drops into the atty, no more or it will flood, roll the cartos around to distribute liquid. Keep them horizontal. Then you should have no issue with them leaking.
Okay, I need to stop typing. Hope this helps!
