Is the unit direct 510 to battery only, or does it have a standard top cap? I build low, and no matter how much I check my build or stay within my safety buffer, direct to battery still kind of scares me! Not to mention most of my drippers have taken a beating and I'm nervous of potentially firing when a connection isn't being made properly due to a short pin or something along those lines. It's just so sexy..... [emoji24][emoji28]
