- Ready made BMS units are either very expensive or don't allow custom setup. This DIY solution is both, very inexpensive and can be set up to your own needs.
Look for yourself.
Have you considered using an Electrodacus bms? Only CA$159 and has all of the flexibility and features plus more that you've been mentioning. I'm using one in our caravan (fully offgrid) connected to our 12v lifepo4 battery. It's awesome! Charging and discharging control, monitoring and balancing all built into the bms. For additional reporting it can also connect to a raspberry pi so definitely worth checking out. The after sales support is phenomenal.
Soo u will put one esp8266 with evry baterí on u module ?
@@ouroldtruck9380 why u dont try one module with several añalog inputs with i2c o with 8 digital pins u got 12analog input u hawe some modules there over internet
@@ouroldtruck9380 You obviously will need a voltage divider with 2 resistors
@@ouroldtruck9380 here is a video explains everything. It's for esp32 but it will work with esp8266 as well ua-cam.com/video/S34R4zg03uE/v-deo.html&ab_channel=G6EJD-David
@@ouroldtruck9380 with the help of a ADS1115 analog-to-digital converter you can even measure all 4 cells with 1 wemos d1 mini. Espeasy is a good choice for someone with no knowledge but unfortunately it has it's limitations :(. Good luck
