Regarding the verdict from Battery Mooch, I found this comment from Mooch on another review for this mod. I can not verify this but I do trust the guys opinion on these things.
"iJoy's claims for the 21700 are ridiculous. I'm rating it 24A/3650mAh and recommend staying below 45W-50W or so due to voltage sag. Use the iJoy 20700 or 18650's like the VTC5A instead for higher wattage."
