sd key ring tank/clearomizer question

[findme75]

so after going over a bunch of ecigs and knowing that i want something that will last long and is stealthy,

I'm thinking about getting the sd maxi 650 510 threaded
ElectronicStix.Com · The SD MAXI KeyRing 650 MAH by Trog (510 Threaded)

So ill probably get two of these due to the fact I want to have a backup battery.I have been looking for 2 tanks/clearomizers/etc for each one as I will have two of these. One can be big for home usage and one can be small for stealth usage. I have researched and heard stories about leaking carts so I have no idea what to pick from and which one wont leak because I sure don't want a leaking cart while im on the go.

what are my options with tanks/carts/clears/etc?
Do I need to purchase 2 of these to get a spare battery or is there a place that sells a bigger battery w/ a charger for less than buying a second one?

You need to be carful with Keyrings. If you get juice down into that automatic switch they are toast.
I use the 1.7 ohm short Smoktech cartos on mine (300mAh Keyrings), and I take the cartos off to fill them.
A SD Keyring will last you a long time if you are careful, if you aren't, and get juice in the switch, you will be replacing them very soon.

I just did a review on one of the SD keyrings. Really nice! I used it a lot with a mini nova and didn't have any issues, but I would be leary of using too thin a juice and having it leak into the battery.

Thanks for the advice. I have read a lot about juice messing up the batteries which is why I didn't want to buy it without talking to you guys first. How does that carto you use work? Do you have to fill it up often? how much does it hold?

on a side note. Are there any manual vapes that are just as small with just as much battery life? I honestly don't mind getting a manual if that would solve the leak issues
