dw, I finally did the modification to to the battery post grinding out the first couple of threads allowing the battery to collapse. I cant really say for sure that I see a difference, other than the mod never misfired with a kick for the first time. So that alone tells me it is getting a better connection.
The question I wonder though, is did we remove a safety feature of a collapsable hot spring? I dont really see it as a hot spring by the looks of the material, but I could be wrong.
im not too worried about it, i only use imr batteries. i also know if i feel any heat, like a lot of heat, to drop my mod. so as not to blow my face off.
