I will design custom bms lithium battery management system and ev charger pcb
About this Gig
Are you building a lithium battery pack and need a safe, reliable BMS PCB that's ready for manufacturing ?
You're i the right place.
I design professional Battery Management System (BMS) PCBs for engineers, startups, and product teams working on EV systems, Solar energy storage, e-bike, portable power banks , IoT device, and Industrial equipment. I deliver is schematic-verified, thermally optimized, and optimized, and fabrication ready for manufacturers like JLCPC, PCBway or Oshpark.
WHAT I CAN DESIGN FOR YOU:
Cell Configurations Supported:
1S to 32S lithium-ion, LiPo, and LiFePO4 packs
Multi-parallel configurations (e.g., 4S3P, 10S2P)
Balancing Methods:
Passive balancing (resistive dissipation) fast, cost-effective
Active balancing (inductor or capacitor-based energy transfer) premium efficiency
Protection Features:
Overcharge protection (OVP) Over-discharge protection (UVP)
Overcurrent and short-circuit protection (OCP/SCP) Thermal cutoff and NTC sensor integration Smart / Communication Features:
Send Me a message with your cell type(Li-ion/Lipo/LifePO4), Configuration eg 16S2p, Maximum Discharge current and target application.

FAQ
What information do you need before starting?
share your cell chemistry (Li-ion, LiPo, or LiFePO4), cell configuration (e.g., 4S2P), maximum charge and discharge current in amps, and your application type. I'll recommend the right package and begin immediately.
Will the files be ready for JLCPCB or PCBWay?
Yes. Every delivery includes Gerber files, BOM with LCSC part numbers, and CPL/Pick & Place files formatted specifically for JLCPCB SMT assembly service. You can upload and order directly.
Can you provide the firmware for the BMS?
Yes! If your design includes a smart IC or MCU (like the TI BQ series), I can provide the basic configuration and firmware setup via I2C/UART.
Can this BMS handle high current applications like EVs?
Yes. I design high-current multilayer PCBs with properly calculated trace widths, copper pours, and thermal vias to handle 50A–200A applications. I also integrate current sensing ICs for accurate SoC measurement.
What if I need changes after delivery?
Each package includes a set number of free revisions. I also offer paid revision rounds for scope changes. My goal is for you to leave 100% satisfied — I don't close an order until you're happy with the result.
