Lichuang Kaiyuan | Verified | DMW-BLK22 Panasonic camera fake battery

## Introducing DMW-BLK22 Panasonic camera fake battery, suitable for LUMIX S5 and other models, input voltage 10-18V, output voltage 8.1V, with PD and QC deception circuit, supports fast charge input. ## Circuit### PCB! [Circuit] Input on the left side, output on the right side. I forgot to add silk screen during proofing. The new version of the project file has been added with silk screen. The upper left corner is the deception circuit. If you do not use the fast charging input, there is no need to solder. ![Deception circuit] ### There are some problems with the BOM table of key components. The key components can be seen here, and the other resistors and capacitors can be seen on the schematic diagram 1. DC2DC converter: SY8286ARAC, available at Lichuang Mall, the price is cheaper than Xobao. 2. PD QC deception: FS312H, available on a certain treasure ## Shell ### Dimensions description Jialichuang 3D printed shell, see attachment, material resin 8111X, dimensions are measured manually, not guaranteed to be perfect, but it can be used. ![In the camera installed in the shell] ![In the camera installed in the shell] ## Cost Regarding the cost, I specially sent a video introduction [https://www.bilibili.com/video/BV1sN4y1F7Nd](https://www.bilibili. com/video/BV1sN4y1F7Nd) ### The assembly shell is divided into two parts, which are fixed with M3x8 self-tapping nails for easy disassembly and maintenance. ![Assembly] ## Finished product![TypeC finished product] ![Finished product] ![Computer test]
