Raspberry pi

Job ID: 30906093

Budget: $10 – $30 USD

I need a partslist, how to wire it up and the code on a working solution to read cell voltages in my LiFePo4 12v system with a Raspberry Pi + breakout boards if needed.
I'd like to read the voltage from every cell in a 4 cell series config and also the difference between the min/max voltage. Also for 4 relays to turn on/off and an email sender depending on certain logic statements. I'd like to put this info online to monitor where ever I am.
