About this Gig

Need a reliable Battery Management System (BMS) PCB for an EV, solar storage system, or BESS project? I provide professional electronics engineering for smart battery management boards, embedded firmware, and production-ready PCB solutions.


I can develop BMS solutions for Li-ion, LiFePO4, NMC and other battery packs, including cell voltage monitoring, passive/active balancing, over-voltage, under-voltage, over-current, short-circuit and temperature protection.


My solutions can integrate STM32, ESP32, CAN, RS485, I2C, SPI, UART, ADC, current sensors, temperature sensors, contactors, MOSFETs and battery monitoring ICs.


Services include:

  • BMS schematic & PCB layout
  • STM32/ESP32 embedded firmware
  • Battery monitoring & cell balancing
  • CAN/RS485 communication
  • BOM & fabrication-ready files
  • 3D PCB visualization
  • Prototype support & testing


Whether you need a compact EV BMS, solar battery controller, or scalable BESS platform, I can help turn your requirements into a reliable electronics solution.


Message me before ordering to discuss your battery voltage, cell count, current rating, communication interface and project requirements.
