Finally, it's time for a mutiny on the Captain. A worthy dual 21700 contender in the Voopoo X217 mod has arrived!
You can definitely throw some 20700 or 18650 batteries (with an adaptor, no batteries included) in this beast, but why would you with the current reigning champ 21700 batteries? Look forward to up to 217w of output with a massive 1.3 inch TFT screen in full colour displaying all your important info.
Voopoo make damn good chips, and the new 32 bit Gene.Fan chip is no exception, offering the amazingly fast firing and accurate output a lot of people remember from the Drag. Even the button is kitted out in matching resin, and the whole mod "breathes" through its LEDs!
To top it off, it fires down to a seriously impressive 0.05ohms, and fits a 30mm tank comfortably. This is an ultra compatible mod that's just as simple as you need it to be. The X217 is a SOLID piece of kit, and well worth a close look if you've even glanced at 21700 batteries before.
