I believe it's the amps you need to worry about; "amps kill."

I believe it takes about 1 amp to kill a person.

This thing is outputting somewhere around 55 amps (if I remember right).

Current availability is not a guarantee of current delivery.

I (current) = V (voltage)/R (resistance)

Typical skin resistance can be as high as 100MΩ (mega ohms) but is often cited as 10MΩ. Even if we assume just 1MΩ (1000000 ohms) skin resistance, then at 2.3V as shown in the video the current would be 0.0000023 A or 2.3 μA (micro amperes).

TIL. Thanks for taking the time to explain!
But for a given resistance, you don’t get the amps if you don’t have enough voltage. V=I*R. Don’t they teach that equation any more?
