I will design lithium battery bms pcb and cell protection circuits
Electronics Hardware Engineer for Power and PCB Design
I design custom electronics hardware for prototypes and production, with a focus on power electronics, battery systems and specialized PCB development. I work on circuit design, schematics, PCB layout...
About this Gig
Battery systems need more than a basic charging circuit. A properly designed BMS must monitor the cells, control charging and discharging, balance the pack, and protect the battery under abnormal conditions.
I design custom BMS PCBs and battery protection electronics for lithium-ion, LiPo and LiFePO4 battery systems. The design can be tailored around your cell configuration, pack voltage, operating current, charging method and protection requirements.
Depending on your project, I can develop:
- BMS and battery protection circuits
- Passive cell balancing
- Overcharge and over-discharge protection
- Overcurrent and short-circuit protection
- Temperature monitoring and protection
- Battery voltage/current monitoring
- Charging and power-path circuitry
- Smart BMS communication interfaces
- Custom battery monitoring electronics
- Schematic, PCB layout, BOM and manufacturing files
Projects can include portable battery packs, energy-storage systems, robotics, e-mobility, backup power and custom lithium battery products.
Send your battery configuration and requirements before ordering, and I can determine the appropriate design approach for your project.

FAQ
What battery types can you design a BMS for?
I can work with lithium-ion, LiPo and LiFePO4 battery systems based on the required cell configuration and electrical specifications.
Can you design both the BMS circuit and PCB?
Yes. I can develop the BMS schematic, component selection, PCB layout and applicable manufacturing documentation.
Can you include cell balancing?
Yes. Passive balancing can be incorporated where appropriate, based on the battery configuration and requirements.
Can you design a smart BMS?
Yes. Monitoring and communication functionality can be included when the project requires it.
What information do you need before starting?
I need the battery chemistry, number of series/parallel cells, voltage, current, charging requirements and desired protection features.
Can you work with an existing BMS design?
Yes. You can provide an existing schematic, PCB, reference circuit or specifications for modification or further development.
