What is the best 'value' 4 money way to read the cycle count of 21700 cells ?

Eventually I'm hoping to write an app. that allows me to extract the cycle count from a cell, but need to crawl before I try & run.

Would like to have a cheap option, because I will not be able to help myself & will pull it apart to check the circuits.

Plus an option that would allow for the cycle count of 8 , 12 , 20 , 40 'bulk' etc. while they are being charged.

BTW - I'm happy to share the code as FOSS via GIT in the future
 
Read cycle count? Can you be more specific what you are after? Exctract?

21700 refers to cell physical dimensions of 21mm diameter and 70mm long so I wonder what it has to do with exctracting cycle count from cell?
