Automatic battery problem discovery can find such short circuits.
Problem: how to distinguish such shorts from faulty voltage sensor measurement?
Shorts may last for less than 1 millisecond, so on voltage telemetry that averages the measurements over 1 second or even 10 milliseconds, shorts will look like a small bump of the voltage, not a deep dip.
A few shorts probably don't represent a problem, but if there are hundreds, and the number of shorts increases over time, this may signify an upcoming cell failure.
