In case of ntc thermistor if the temperature increasing the resistance decreasing. Usually the battery pack requires 45 volts and 300 500 ma current for fast charging. These battery packs have 3 nimh or lithium cells having 12 volt rating.
Threshold pin 6 is supplied with a voltage set by p1 and trigger pin 2 is supplied with a voltage set by p2. Begingroup what about the fourth pin. However a li ion battery which is employed inside cell phones are pretty sensitive to bad voltages and may just blow off causing serious life and property issues.
