DISCLAIMER... LITHIUM BATTERIES CAN BE VERY DANGEROUS. Do not attempt this at home unless you thoroughly understand what you are doing. I cannot be held responsible if you mess around with a lack of understanding and hurt someone or start a fire. This is not intended to be an instructional "how to" video but rather to document my process for educational purposes.
