700F Super Capacitor Protection PCB - Reverse Engineer Update

A final look at the protection PCB for the 630F and 700F 2.5V Nippon Chemi-Con supercapacitors. In the previous video, I missed a tiny track between the TL431 ref pin and Vcc (or CAP +). So this time I take a look at the internals of the TL431 and add a red indicator LED to the circuit.
