cells check - defining LI-PO batteries

I just tested a HP clone battery - HT03XL - and didnt realise that the test result (internal resistance value) is incorrect for LIPO batteries.

Suggestion: A field to define (by user) whether its LIPO or not - perhaps the test can then be accurat according the type of the battery ?

Good proposition. Additionally it could be added number of parallel cells field so customer could enter proper battery configuration and Cells Check algorithm will take it into account.

Why do you say IR is incorrect ?

@azzido because the moderator - and also a previous post some time ago advised, that the internal resistance of a LIPO battery
is different - and in my understanding - that means  the definition of  good - poor - bad  for a LIPO battery is not correct.

Yes, the IR of a LiPo battery could be different than the IR of a LiIon battery but this does not mean the IR is not computed correctly.

The IR is computed correctly. The relation between IR and the classification Poor, Good, Bad could not be accurate for all Batteries. The algorithm that outputs the cell estimation as Poor, Good and Bad is not perfect. There are missing inputs like cell capacity, number of cells in parallel, cell profile, etc. The algorithm is already complex, adding more inputs will make it more sensitive.
