Hello, I'm a DIY'er working in the construction industry as an electrician and project manager. In the process of installing an off-grid, battery back up, whole house inverter system and building my own 48V LiFePO4 battery pack, I discovered that the Battery Management Systems (BMS) available currently are really lacking or are VERY expensive for the better products. I believe an opportunity exists to develop something reasonably priced but with set of features that NO ONE else is offering at this time. The good news is there is no need to reinvent the wheel. All of the components are actually available but not in an integrated package with user friendly network communications. What I would like to accomplish could be described as reverse engineering a specific set of hardware products and designing a circuit board to fit all the components together along with WiFi and/or network connectivity that serves up a webpage based menu for setting the various options and viewing cell voltages, error messages etc. I have quite a bit more info to share if you are interested. Thanks Royce

I have been looking at and studying the idea of a 48V based battery power system. My concept is more complicated than what you need here. You are only looking at the battery management portion of it. Very good ICs that monitor and balance battery stacks are expensive. As an example -- I like AnalogDevices/Linear products. They have the LTC6811-1 which monitors up to 12 batteries. That is a $20 part in low quantities. They provide you all the example circuits you need to make the core project work. For a 48V LiFePO4 system, you will likely need 2 of these. Then you need a circuit that will Buck/Boost the battery voltage up to a consistent 48V. Again, good parts are expensive. I normally work with LED lighting... and I have experience with power circuits and some charging circuits. I'm also working with the ESP32 inside about 4 projects. That part provides Wifi and Bluetooth connectivity. The product could be accessible through a simple mobile app. I'm over in the Philippines where my cost of living is lower -- and I'm close to China where I source some of my parts (like the circuit boards). And because I already have some interest in this -- I may have some of the parts here already that might match your project needs. I could probably be more helpful if I could ask you questions directly. Let me know if you want to do a video call. Thanks.
