I have the same battery (if you're talking about the one that screws straight into the charger to charge, not the one you put an 18650 in) and I used to use it with a TOBH. If you are talking about the CF sub ohm battery, not the CF mod, it will not fire down below .4ohms. When I was using it for my RDA I tried to build it about .6 or .7, which wasn't that hard to do. It works OK when it is fully charged, but as the battery drains it lags (takes longer to heat up the coils) If you build below .4, it will not fire, the button will just flash. It does not last too long when using it that way, and since you have to plug it in to charge instead of swapping out the battery, it's kind of a PITA. It will at least give you an idea if you're going to like an RDA, though, without having to spend money on a different mod.
ETA: It's somewhat regulated, so as long as you are building within the specs of the battery (that link says .3, but in my experience it needs to be .4 or higher or it will not fire) it is not going to be dangerous. Someone will be along shortly I'm sure to tell you the specifics of wattage, etc. But if the battery is too low to safely fire, it will not allow it to fire, nor will it fire if the build is too low or if there is a short.
