About this Gig
Need a safe, reliable battery management system for your lithium battery pack? I design custom BMS circuits tailored to your cell configuration, capacity, and application from simple single-cell protection to advanced multi-cell systems with balancing and monitoring.
With solid experience in power electronics and battery safety design, I deliver complete, manufacturable solutions covering overcharge, over-discharge, short-circuit, and over-temperature protection.
What you get:
- Custom schematic based on cell count and chemistry
- Optimized PCB layout (2-layer or multi-layer)
- Cell balancing circuit (passive or active)
- Protection: OVP, UVP, OCP, thermal cutoff
- Component selection with datasheets
- Gerber files ready for manufacturing
- BOM
I work with Altium, KiCad, and Eagle, following best practices for safety margins, PCB isolation, and current-carrying trace design critical for battery applications.
Whether you're building an e-bike battery, drone pack, power tool battery, or energy storage system, I'll make sure your BMS is safe, efficient, and ready for production.
Message me before ordering with your cell count, capacity, and application so I can confirm the right approach!
FAQ
How many cells (series/parallel) can you design a BMS for?
I can design for a wide range; from single-cell (1S) to multi-cell configurations (e.g., 4S–14S). Share your pack configuration for confirmation.
Does the BMS include cell balancing?
Passive balancing is included in Standard and Premium packages. Active balancing can be discussed as a custom add-on depending on complexity.
What battery chemistry do you support?
I primarily design for Li-ion and LiPo batteries. Let me know your chemistry (e.g., LiFePO4, NMC) so I can tailor the protection thresholds correctly.
Can this BMS handle high-current applications like e-bikes or power tools?
Yes, I can design for higher current ratings; just specify your max continuous/peak current so I can select appropriate components.
Do you test or simulate the design before delivery?
I verify circuit logic and protection thresholds through simulation and calculation. On-site hardware testing isn't included but I provide guidance for bring-up.
