is it possible I have a bad battery I'm not aware of and it's shorting out my mods? 2 mods in a month now and only common denominator is a battery. I hadn't used these particular battery's since my last mod quit working, coincidentally (after I put in different battery's ) because I needed to wrap them and just got around to it yesterday and as soon as I changed the battery in my mod or maybe it was later not sure but it hasn't shown a sign of life again .. this one a tesla last one predator.. pissn me off! If I had a bad battery how would I know or is that possible. Actually the battery ppl told me it wasn't but I want a second opinion now that I've got 2 mods down...
