, 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. (V
I
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 V
I
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±0.07 V and 10.76 V ±0.09 V.
