    Hi Belhaj,

    The device pre-configurations assume lithion ion cells and sets them for a charge voltage of 4.2V per cell. If these default settings are not exactly what you need, you would choose the closest available and then use a uC to reprogram the default values over I2C.

    Your resistor-divider looks good. Based on your description, everything in the post looks correct.
