About this Gig
Are you in need a reliable, custom Battery Management System (BMS) or fast charger circuit related to your specific lithium ion or LiFePO4 battery pack?
Off the shelf BMS modules often lack custom dimensions, communication protocols, or specific current capabilities. I design custom BMS and charger hardware using KiCAD and Altium Designer that strictly adhere to safety and thermal standards.
Capabilities;
Cell balancing circuits (Passive & Active)
Over-voltage, under voltage, over current, and thermal protection
USB PD fast charging and Solar MPPT charging circuits
Microcontroller telemetry integration (I2C, SMBus, CAN bus)
Heavy copper pours and thermal via management
What you receive;
Complete schematic PDF and native KiCAD/Altium source files
Manufacturing Gerbers (RS-274X) & Drill files
Bill of Materials (BOM) with manufacturer part numbers
3D STEP enclosure modeling files
Why work with me?
Safety is paramount in energy storage. I engineer wide creepage/clearance distances and high current trace widths to prevent overheating and thermal runaway.
Send me your battery pack specs (S/P rating, discharge current, charge voltage) to get started today!

FAQ
What key specifications do you need to start my BMS or charger design?
I need to know your battery chemistry (e.g., Li-ion, LiFePO4, LTO), cell configuration (e.g., 4S2P, 13S), maximum continuous and peak discharge current, charging voltage/current, and physical dimensions.
Can you design for specialized battery management ICs from TI or Analog Devices?
Yes. I frequently design around industry-standard chipsets, including Texas Instruments bq-series (e.g., BQ76940, BQ25713), Analog Devices / LTC, and Maxim Integrated fuel gauges and protection ICs.
How do you handle thermal management on high-current boards?
High-current paths require strict heat management. I calculate copper thickness (1oz vs. 2oz+), use heavy copper pours, stitch thermal via arrays under MOSFETs, and size traces properly to keep temperature rise within safe operational lim
Can you integrate communication protocols like CAN bus, SMBus, or UART?
Yes. I can route isolated or non-isolated telemetry communication lines (CAN, I2C, SMBus, Modbus) so your BMS can transmit cell voltages, temperature, and State of Charge (SoC) data to an external controller or display.
Will the layout meet safety creepage and clearance standards?
Absolutely. Energy storage systems demand high safety margins. I enforce strict clearance and creepage rules between high-voltage sections, ground planes, and low-voltage digital logic to prevent arcing and short circuits.
