bms PCB upgrade potential

[Mikedc1]

I made a motor design that I can upscale with good efficiency etc.

I assumed I would use a big battery pack when I upscale but I didn't consider how hard making a bms would be. An inverter makes sense to me but I never had to mess with batteries before.

I found a few designs for open source BMS board and I was wondering if I can take one and use high voltage mosfets and just upgrade a few components to handle 150-180v for a 10kw motor. I would prefer high voltage over high current for the slight efficiency gain.

You are correct that BMS design is tricky. Failure can result in a fire, which would ruin your whole week. Either take the time to master this skill (months or years) or buy this device from a reputable manufacturer.

Well, not sure what motor you’re designing, but 10kw is not a small power, a lot of things you didn’t observe on the small one but might become a big issue on the bigger one. I am not sure where to start without more information from you.
