So a mech mod will allow you to vape with super low res coils. Can someone tell me the pros and cons and why it seems so popular now? Based on my limited understanding, it can be dangerous (overstressing the battery) and if you make your own coils you have to watch you don't short out anything. It seems like "chasing the dragon", this quest for the most intense vape. By vaping at such low ohms, doesn't it drain your battery faster? Resulting in the need to charge more often, and therefore in the long run, a decreased battery lifetime? Also what are INR batteries? Are they similar to IMR batts? Thanks.
