This problem still remains common with even popular cars like Tesla. Addendum: If you have a battery module pulled from a Tesla pack, it will still have the address it was assigned when operating in the Tesla, so it won't respond at the 0x00 address. A simple $20 BMS that works on its own is all I need. Tesla BMS and Arduino ESP32 succeeding to talk. It will communicate with a Victron system in order to build a home energy storage system. x/LC board, I use Teensy 3. On Some pack if the cell have wires not ribon the wires can oxidate and have problem on contacts with battery plate. Battery Management Systems (BMS) is the most important component in a battery pack essential for the battery pack’s safety. 3V chip & board so 5V could damage it.
