16S fully charged gives you 16*4.2 = 67.2V
Simple calculations :
30mA gives the human body respiratory paralysis (you already feel pain under 10mA)
Human body resistance is roughly something around 2000 Ohm (wet body, considering electricity breaks down human skin and therefore lowering the resistance)
Max voltage would be = 2000*0.03=60V
At 60V with 0.03A, you are probably nearly dead. Imagine 50A+ flowing through your body…
I wouldn’t go above 14S personally. I already touched 110V with a current around 20mA that flown from my hand to my feet 5years+ ago. It took me more than a whole week to recover from the pain in my elbow, and I somehow still feel the pain there today…
Beware of electricity friends, It’s all great and fun until something bad happens…
