6-S ArduCopter Li-ion BMS

@AwaisChaudhry

Hello, I understand you need a purpose-built 6S ArduCopter BMS that monitors 6-cell Li-ion packs in real time, balances cells automatically, protects against over-charge/discharge and shorts, and streams MAVLink data over CAN so the flight controller reads live battery status. I will design a reliable system with a robust safety layer, precise cell voltage/temperature sensing, and a compact PCB (KiCad or Altium) with readily sourced parts. The firmware will run on STM32 and provide continuous pack and cell data, implement cell balancing, handle fault trips, and publish standard battery status messages over MAVLink-CAN so Mission Planner/QGC show accurate telemetry. Approach: I’ll build a modular BMS core with a dedicated balancing engine, watchdog safety, and a MAVLink over CAN stack. The schematic/PCB will be optimized for 6S Li-ion packs, with proper isolation, decoupling, and current sensing. The deliverables include all PCB files, a BOM, and concise configuration notes to integrate with your CAN bus and ArduCopter parameter set. I’ll also provide bench/test videos or data showing trip events and telemetry accuracy. Do you have a preferred CAN transceiver or clock source for the STM32? Questions I will ask you include: - Do you have a preferred CAN transceiver or clock source for the STM32? - Is there an existing MAVLink-CAN profile you want mirrored, or should I align with the standard ArduCopter battery status messages from the docs? - Any space or thermal constraints

Best 6S Li-ion BMS Development Expert for ArduCopter Systems! ⭐⭐⭐⭐⭐ Dear Client, This project is not just about reading cell voltages and sending telemetry. The real challenge is building a 6S Li-ion BMS that can be trusted on three fronts at the same time: accurate pack health monitoring, stable balancing and protection behavior, and clean Mavlink-over-CAN reporting that the flight controller sees as dependable live battery data. That is where I can help. For a system like this, the important part is not only measuring voltage, current, and temperature. It is making sure the balancing logic, fault response, protection thresholds, and CAN telemetry all behave as one coherent system. I would approach this as a reliability-first embedded power design: measurement accuracy, safe protection handling, clear CAN mapping, and a board/firmware package that is practical to validate on a real 6S pack. A few key questions from my side: 1. Is your preferred fault response hard disconnect, current limiting, or a staged warning + protection model? 2. Do you already have a preferred MCU/CAN architecture, or is that still open? 3. Is the first priority fastest bench-proven prototype, or a more production-conscious BMS from the first revision? If you message me, I can also outline the most practical architecture for keeping telemetry accurate and protection behavior predictable from the first build. Best regards, Prat PCB Must Innovations

@FranciscoSilvi

Hi There! - As you can see from my portfolio on my profile, I have extensive experience developing PCBs and industrial equipment, including a 24V UPS that actively charges and balances the battery using a BQ76920 battery balancer and monitor. It can be controlled via I2C with a small MCU, such as an STM32C011F6U6 or similar with an integrated CAN interface. I believe I am a strong candidate for this project. -I'd like to chat with you to better define the project details. This isn't an AI-generated bid like most, so it's taking me some time to write. I hope we can work together. Best regards!

@shykhAbubakar

Hello, I have TOP NOTCH similar work experience on UAV power electronics and CAN based telemetry systems. The project included embedded systems and PCB design. Before moving forward, please confirm: Should the cell balancing be passive or active? Is there a preferred CAN transceiver IC family for compatibility with your flight controller setup? Tools I Use • KiCad / Altium Designer • STM32CubeIDE / Arduino IDE I am ready to deliver a purpose built 6 S Li ion BMS that ensures telemetry, operation, and long cycle life. The focus will be on cell balancing, CAN Mavlink communication, and clean documentation. The documentation will be aligned with IPC and UAVCAN standards. Best regards, Abubakar Muhammad

Rugged, reliable, and precise - those are the words that define my work and these skills fit perfectly with your project. With extensive experience in Electronics and Embedded Systems, I've developed a keen understanding of battery management systems (BMS) like the one you're seeking. Designing BMS to monitor battery health in real-time and perform cell-to-cell balancing effectively is something I have excelled at in my past work. As someone who places a strong emphasis on safety, I will ensure that the BMS I develop for you not only actively UPERVENTS potential hazards but also efficiently communicates critical information to the ArduCopter. I don't just design; I deliver! That's why you can expect your deliverables to be on-time and beyond satisfactory with clear documentation as per your needs. To further instill trust in my capabilities, I am more than willing to provide bench test results or even a demo video showcasing the protection capabilities of your 6-S pack with utter precision. Working together, we can ensure your ArduCopter not only flies but does so smartly and with utmost safety consciousness powering this dream is what I would love to do for you!
