anyone else had this setup? any issues? Mine is a mess. The kanger fires every time on a standard ego 510 type battery, but if I screw it into the lavatube till it's snug (not tight just not rattling around) it reads 9.9 ohms and won't fire. If I leave it very loosely screwed in it sometimes fires. Are they just not compatible? Both said 510 connections. Very frustrating.
