Temperature Sensor
To collect battery temperature data for temperature compensation so the controller can accurately charge
the battery. The temperature sensor is connected via interface 6.
If the external temperature sensor is not connected or damaged, the controller defaults to the internal
temperature information.
The controller is shipped with an 80 mm long cable temperature sensor. Should a sensor with a longer
cable be required than this needs to be ordered separately.
