Been using mods for 11 months now. I'm still worried about these fear mongering articles where guys (usually due to their own mistakes) have big problems. I use authentic (I think) Samsung 25rs and Sony VTC 4s from Myepack (i'm from the UK). The company has been recommended on here a few times. I use an intellicharger D4 bought from Nitecore. I use a sigelei 150 and 75 mostly with an authentic troll rda or clone kayfun. I build quite high usually to avoid stressing my batteries at all. I occasionally build .3 coils and run them on my mech. It worries me to push the 25r to 15 Amps when it is capable of 20A. I am worried about getting a faulty battery. I know it is a 1/1000000 chance. Any recommendations or ideas would be appreciated. Thanks
