External LI-Ion Battery Pack/ Powerbank for my Camera - Components, Battery and Design

Hey, guys :D
Today I'd like to show you part 2 of a new project of mine. This is a LI-Ion Battery Pack for my camera that also serves as a power bank. It has around 11000 mAh of capacitance and is really versatile and portable.
My camera is the Panasonic Lumix FZ82, it records all my videos in 4k 30fps but its batteries die way to fast so here's my solution for the Problem.
