I will design bms battery charging usb c pd lithium protection pcb

Building a portable device powered by a lithium battery? I can help turn your idea into a custom battery management system (BMS) or USB-C charging PCB designed around your device's power needs and available space.

I design battery protection and charging circuits for 1S4S Li-ion, LiPo, and LiFePO4 battery packs. Whether you need overcharge, over-discharge, and short-circuit protection or a compact USB-C charging solution, I'll create a clean schematic and organized PCB layout tailored to your requirements.

Your design includes a 2-layer PCB layout for up to 30 components, carefully planned power paths, trace widths, and thermal considerations. You'll receive Gerber files, drill files, a BOM, and editable source files in KiCad, Altium Designer, or EasyEDA. Two revisions are included.

My goal is to make your design process straightforward, with clear communication and well-organized files ready for manufacturing.

USB-C Power Delivery (PD), cell balancing, high-current designs, and existing BMS board reviews may require additional work.

This service covers design files only, not physical manufacturing, battery testing, or safety certification. Please message me before ordering
