/diy/ - Do It Yourself

I want to wire my raspberry pi directly to a power bank so I can stick it all inside a gameboy.

I want to keep the ports accessible on the outer case so can't just use some small cable inside to connect things. I have tried connecting wires to the power out and ground on the back of the usb port on the pcb but this doesn't seem to be working.

Am I a retard for thinking I could just wire the battery directly to the raspi and ignore the charging circuit for powering the pi.

I'm very new to electronics and this is my first time messing around with batteries, trying to not burn my house down.
