As is well known, the Hadron 220 has battery rattle with some 21700s. (Apparently the 217's are not all one standard width but vary by a few mm between manufacturers.) Steam Crave included little o-rings with the mod to put on thinner 217s to eliminate rattle.
In my case I have Molicel P42As (which have a lot of rattle without the o-rings, so I had been using them)... but to avoid using them, I instead double-wrapped the batts. Ordered clear batt wraps from eBay for $6 shipped... put them right over the factory wrap... now no need for o-rings and no rattle -unless- I shake the mod hard like I'm trying to mix spray paint... then there is a slight rattle. Thicker batt wraps would have eliminated even that, but in handling the mod normally there is no rattle whatsoever, so I'm super satisfied.
Just thought I'd pass it along in case it hadn't been mentioned prior...
