It has been very frustrating over the past couple of weeks. I have a K100 and shorted out 3 Sony VTC5's and 2 Orange batteries (not sure what they are called but my buddy at the vape shop said they are safe for sub ohming to .4 ohms). I has just gotten a Clone Magma from ebay (Item number 380998003613). When the Magma is screwed on too tight it shorts the battery. I had a Patriot before and this never happened. I am sure that it is the Magma but it might be. Has anyone encountered this issue before? Is there a fix? Is there anything I should look out for? Should I play with the screw on the bottom of the magma? I just do not want to spend so much money on these batteries anymore.
