From the project

Manufacturing-ready Li-Ion Battery Protection PCB designed using KiCad 9 with complete documentation, Gerber files, simulations, and manufacturing package.

This project demonstrates the complete PCB design workflow, including schematic capture, PCB layout, routing, copper pour, design rule verification, Gerber generation, and manufacturing documentation.

This PCB provides a simple yet reliable protection and monitoring solution for a single-cell Li-Ion battery.

- Reverse-current protection - Overcurrent protection - Battery voltage sensing - Power indication - Test points - Manufacturing-ready outputs
