The BQ27Z561 datasheet indicates
The TS input is enabled with an internal 18-kΩ (Typ.) linearization pull-up resistor to support the use of a 10-kΩ (25°C) NTC external thermistor, such as the Semitec 103AT-2. The NTC thermistor should be connected between VSS and the individual TS pin. The analog measurement is then taken via the ADC through its input multiplexer. If a different thermistor type is required, then changes to configurations may be required.
The recommended thermistor's specs indicate its B value is 3435K
Meanwhile, the thermistor on our battery pack has the same specs, but the B value is 3380K
Can this be used without too much difficulty, or shall we have the battery manufacturer use a thermistor with 3435K to match the recommended profile from the datasheet?
