Batteries. Lithium-ion batteries are an amazing and powerful way to store and transport a large amount of electricity. They can power our phones, laptops, even electric vehicles and YES, the vaporizers we all love. Of course, anything that has loads of energy stored inside can be dangerous. How dangerous? Very dangerous! The good news is that companies like Sony, Panasonic, and LG (to name just a few) go to great lengths to produce reliable and safer batteries for all of us, but how do you know that your batteries are actually from a good company?
