Notes:
1) Value of R5 determined by discharge current and capacity of battery pack.
2) Discharge FET is logic-level compatible in this application.
3) DC return of discharge FET must be connected close to negative battery terminal.
4) Resistor is needed only if a thermistor is used. Value may change depending on thermistor.
5) Regulated supply
6) Power ground; others are signal ground. Connect signal ground to power ground
at negative battery terminal only.
