So I was working way too hard trying to understand how to make the 4s lipo batteries work, and I realized that knowing me this battery config probably won’t work and it’ll blow up in front of me, so I decided to use a power bank. After talking to Gemini and other AI’s I went with this power bank. It is extremely thin and good enough to power the whole laptop. https://www.amazon.com/Baseus-Portable-Charger-20000mAh-Charging/dp/B0DK8V9LSV. The power bank is even cheaper than some 4s lipo options so I guess switching is the better option.
