Been vaping for a few weeks now and have been scanning the forums almost daily without creating an account until now. I ordered some panny ncr18650b for my new SiD and they were too wide to squeeze in. They were protected circuit batteries. I found out they fit if I removed the outer shrink wrap layer and the protective circuit with the wire leading from + to - terminals to complete the circuit. I tried searching if this is safe online with no luck except I found that the laser pointer world does this quite often to removed the overdraw safety feature. Since my SiD already has protective features will this be okay? There is still 1 layer of shrink wrap label on the battery. So I'm assuming I simply changed it from a protected Li-Ion battery to a non-protected Li-Ion battery just like an AW or Efest. Any knowledge would be highly appreciated thank you very much and vape on.
