@D4lt0n @computersandblues Here's a photo, it has an extra USB C port attached on the left, which feeds power to the battery protection board (which I cut away from the spicy pillow)
There's one diode in series to drop down the voltage (the board cuts power if it gets up to 5V) and a capacitor to prevent instability
As for the software it currently has the sdm845 u-boot fork, and a Debian install with the kernel from postmarketOS, the reason I recently switched to Debian was that musl and the lack of systemd can be really annoying, especially with game servers
