Hey! I like the new picture-in-picture! Good to see you. The TL431 is an 'old' friend so to speak - found in most Chinese switch-mode PSUs feed-back channels these days, and allows for tweaking the final output quite a bit. I've used it in thermal control and a range of other applications. Great little device. Thanks for your excellent, interesting and concise videos, and new years greetings from Iceland.
Yes. This would directl, adjust the charge voltage and use ahigher input voltage. I used this with a 18V Li-Ion battery with 24V input. That is coming later tody.

Welcome back 😊
Good video and helpful. What if you wanted to make a 12V Li-onP4 charger using 16850 cells. Would your circuit work?
Yes. This would directl, adjust the charge voltage and use ahigher input voltage. I used this with a 18V Li-Ion battery with 24V input. That is coming later tody.
