Hello.
A Worx brand grass trimmer behaves very well from its freshly recharged battery for a few minutes and then stops running. After a pause, works fine again with good power until cycle repeats. Seems the battery disconnects the load when its temperature sensor missreads? the pack. Another pack works fine so it is not the motor producing the failure.

Individually, the cells inside are well balanced and of proper voltage, not heating. How to trick the thermistor to find if needs more resistance or less resistance added to behave well ? It is a thermistor suspicion unless you suggest something else to diagnose.
