17.38 0x2E VAUXVoltage()
This read-word function returns an unsigned integer value representing the scaled measured voltage from
the VAUX pin, in units of mV if
[VAUX_SCALE] = 0, and 10 mV if [VAUX_SCALE] = 1 with a range of 0
to 65535. The returned value = VAUX × VAUX Gain .

17.40 0x30..0x3E CellVoltage1..15()
These read-word functions return an unsigned value of the calculated individual cell voltages, in mV, with
a range of 0 to 65535.
CellVoltage1() corresponds to the bottom-most series cell element, while
CellVoltage15() corresponds to the top-most series cell element.
