Don't forget to compensate for any battery charging circuit as well. In Canada, alternators can go beyond 14V DC.

Hi Robert,
thanks for the reply
i have the hardware issues under control, there is an Li-ion pack with a fuel gauge being specified and my question is strictly about the firmware compatibility of the I2CRead I2CWrite compatibility with the SMBus and the SBS on fuel gauge type chips
