It's just a dial on the side. In the first episode the team were warned not to set it above four or something, whic is the stun. James cranked his up to 10, which I imagine drained the battery in one pop. That's probably not relevant. Point is, they CAN be lethal but aren't designed to be, it's just how much power goes into each shot.
