lead shouldn't be heated above 500°C unless you like delicious lead fumes

This had tons of potential, if only they would have implemented it in a more controllable manner. I really don't mean to be harsh but
Currently this is Dangerous, Irresponsible and completely lacking any kind of regard for life or limb. What happens when U Short that cable together. U will weld those jumpers together and run the risk of blowing up that battery, possibly igniting the oil in the car, in the garage or the hydrogen fumes from the battery.

Maybe for your next one, try making a safe version using a method that is much harder to short out. For now, Fail. But Original concept is a definite starting point.
