Lance Wallen ran a vape shop for about five years. He studied LiPo batteries from the perspective of selling them to his customers, who compete in vaporizer cloud blowing contests. If a blown LiPo on a copter is bad, imagine how much worse a blown LiPo is while you're taking a hit off of a vaporizer! Lance and I talked for several hours about LiPos and I have edited the conversation down to seven parts.
