BATT Input
The voltage applied to the BATT input, used for battery voltage detection, is a voltage potential, derived by a
voltage divider resistor network (100k
or higher recommended) or other means, that represents the voltage of
a single battery cell during charging. If a single cell only is under charge, a current limiting resistor (100k
or
higher is recommended) should be connected between the battery and BATT input.
