What SueGeo said, it has two 18650 batteries. One battery should keep you going all day, easy.
You will need some kind of atomiser system as well since they aren't included in that kit. You can go with some Vivi Nova knock-offs from FastTech, Look for some better Vivi Novas closer to home, or go with some other system. You might like to look at CE5 and CE3 clearos, and the Protank.
If you are game, I can actually recommend the Protank - it worked really well out of the box for me, so I'd have to say that while it is an advanced delivery device, it might be suitable for a beginner.
You may want to try all of these devices on your Vamo. Different things work for different people.
The Vamo V2 may not come with an instruction manual. It's pretty simple but contains some important information; you can download one
here. In particular, make sure you set the Vamo to RMS mode (program No 2) when you get it. It is set to No 1 mode by default.
