See billbeck's post above. The linked battery is not variable voltage. So you could use it to start with, but you will more than likely need to upgrade pretty soon to get the VV that you'll need to improve your vaping with different heads / toppers.
That said, many people do start with a non variable ego type battery. But many people also out grow it within a few weeks. My experience only...
You are wrong.
I asked FT to get that product in stock.
After they posted it without any mention of Vv or twist, i asked them to confirm it was in fact a twist, which they did. I then asked them to change the description to reflect that. In short it is a Twist vv battery.
