The V490 boards self calibrate using a "parasite" voltage detection as per the datasheet. This appears to be not required and is actually causing incorrect voltage readings to be returned....

This ticket is to investigate seemingly random reboots of the controller (often related to also losing WIFI STA) with latest firmware version [Release-2023-12-27-12-02](https://github.com/stuartpittaway/diyBMSv4ESP32/releases/tag/Tag-2023-12-27-12-02) May be related to #239
