Connect the battery : B+ connected to battery positive.
Output voltage detection, detect output voltage or battery voltage ( if battery is used).
Output voltage. Can't connect the battery.
Temperature sensor can be connected to the unit to allow temperature compensation of the charging voltage.
If the sensor is not used, the charger still works normally.
Reference example:
Connect 100KΩ Thermistor(THINKING) on NTC. The output voltage will change along
