Comparator threshold setting of the BT3554-50
QHow should I decide on the threshold values for the comparator of the BT3554-50? My target battery does not show the internal resistance in its specifications.
In general, the following is recommeded:
1) Measure the internal resistance of the fully charged new battery.
2) Set "x1.5" for WARNING and "x2.0" for FAIL
Then, set the rated voltage for the voltage threshold.
The internal resistancce value differs by the battery brand and model so be sure to different settings for each battery if you have several battery models to measure.
