arduino/esp based BMS

I'll be using The 7210A to charge up my pack since it will be a small system (520watt system) and a grid tie inverter with limiter.

I have anESP32 on order to see if I can a) monitor voltages (14s) and b) create a discharge circuit of around .75 - 1.0 amps

How to read multiple analog Read sensors (should apply to voltage readings i think):https://forums.adafruit.com/viewtopic.php?f=25&t=11597&start=60
Discharge circuit:

Good idea?has any one tried these methods or have had success/failures?

Check out BQ76940 that do all above in same unit kind of

Looks good. I will probably still try to use the ESP to send all the data to a server. I feel like this will be a year long project.

I did draw up a design with ESP with the BQ but never finnished it. I do have it somewhere if you want it or
Its not tested nor did you check all components. I left out the balancing part though. But can be added fairly easy if wanted
