† VI, for a 2-cell, should not exceed 9.1 VDC for the 1-A charge rate and 10.6 V for the 0.5-A charge rate. (VI is the input voltage

to the bq2400x IC, pins 2 and 3. The power supply source voltage, at J1, is 0.1 V larger than VI because of the regulated voltage
drop across the current sense resistor, during constant current regulation.)

‡ If J2 is set to APG, then the chip will be disabled when the input is outside of this range: 4.02 V
