Ah, even my manual 808 from v2 has the hole to the battery. This lead me to start asking before I buy about sealed batteries. The Volcano Magma KIT comes with 2 auto batteries, not sealed. So if I want to have a smaller ecig along that line, it would be better to ala cart 2 manual batteries which are sealed, but note, that fancy battery pack won't work with the manuals. I'd rather have my batteries sealed than a fancy recharge pack. The infernos are sealed and manual. I think it pays to ask ahead of time now that I know what questions to ask - I didn't a month ago when I got the v2's. Hubby's v2's are doing just fine, he never did anything with them except use the prefilled carts. I on the other hand tried that carto refill which is how I ruined my autos by juice getting in them.
Today I used the Magma MEGA cart with my Inferno. Wow. Now that I learned the correct way to fill it (there are two holes on the side of the bottom ring and you use a special straight tip syringe and push the liquid through one of those holes) I gotta say, it lasts a long time. I think there is a funky taste initially, why I don't know since they are all ceramic inside, but once that was gone I was loving it. So I have one Inferno battery set up with the drip tip and the other with a cart. I don't get bored LOL. And since I've got the PT I don't have to worry about running out of charge.
My goal this week is to practice not using it so much. I very much like the JC Expresso but I use low nicotine so I probably get more flavor. Tomorrow I am going to use the chocolate truffle. Hmm... we'll see how that cutting down works out.....
