Battery cell temperature data only available from the first 4 cells?

GivTCP (via MQTT broker) produces a lot of data, which include voltages for each of the 16 battery cells. However, for temperature there is only data available for cells 1 to 4. Why this limitation?

Because there's only 4 cell temp probes inside. Each cell doesn't have it's own I believe.

hoggy Correct and the cell temperature 4 is not the temperature of cell 4 - its the temperature of the fourth sensor. The four sensors are distributed throughout the pack.

ok, thanks

Sensors 2 look to be near the surface, 2 deeper inside, 1 and 4 tend to move faster than 2 and 3
