I don't think that's a great way to buy a 510. How would you drip to try juices? You cannot drip without an atomizer. And what would you do if you ran out of cartos?
Only place I know with a 510 (non-Joye) carto kit is NoSMokeVA.com and it's a kit with a PCC - search for PCC. But you could ask Cignot - they sell a no-box Joye 510 kit and might be willing to substitute cartos. I would not even want random cartos though. I like Boges. I hate SLB cartos.
You know cartos are disposable right? You might get 1-2 weeks out of each if they are Boge. I can hardly get 3 refills out of an SLB before they start dragging really hard.
I strongly recommend MANUAL batteries. If you want to drip with a drip tip on an atty, and if you don't want cartomizer leaks to kill your batteries, buy manuals. You will get no sympathy here if you buy autos and damage or kill them with leaked juice. 510 manuals are totally sealed metal on the threaded end.
