I'm pretty new to mods so go easy on me. Well I ordered some Panasonic CGR18650CH batteries off of Amazon, they're also Li-ion. So originally I didn't really think flat top batteries wouldn't differ then the button topped ones. I have a Chi-You mod Ver.2013, the adjustable pin is an alright addition, but I feel it's not reaching the battery? Also when I do get it into a spot, my mod wont fire at times and ends up firing randomly by itself even though it's not touching the pin or if I looked my mod. Can anyone give me an idea what's wrong? Or any tips?
