I have a sigelei zmax on the way and plan on using the 18350 double stacked in it. My questions are 1) what is the best batteries (brand and protected or unprotected) 2) do I have to use that brands charger to charge them or is a charger that is made to charge any 18350 batts fine? There is so many threads and info on this throughout the forum I am afraid I am just lost. I don't want to blow up my first vv and hearing about batteries exploding and everything is making me a little nervous since I am having a hard time following. Also I see they have the vape safe fuse I am assuming this would be a good idea since I am wanting to eventually try the RBAs or will it hinder the performance of my zmax?
