Definitely do it. I can't say enough good about my eVic. It's my standard setup, and for good reason. The voltage limit was an issue I was worried about too, but honestly I vape my cartos at 8-9W and it still barely gets to 5 volts. My BCC's I keep at 7.5-7.8W cause the taste burns after that.
One oddity: the eVic stops your power on higher resistance coils at lower power. My 3.2 ohm cart can only get to 7.8W which is about 4.99 volts. I suppose that's why, the 5V limit.
