ROCKPro64 Battery Power Supply
#8
Thanks guys, I just threw that number out. It seems like the price of components are all over the place. I just picked up a couple Waveshare e-ink displays for $21/each. I'm still kind of blown away that this project could require multiple laptop battery cells, when we can use usb-c to power and charge so many complete laptops.

From the number of similar questions on this and other boards, it seems like there's a strong market. Unfortunately shipping batteries from China would probably take a long, long time.

One thing I can say is that the 12V barrel-type requirement was clearly described before I bought the board, so it's not a surprise.
