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...

I only did 4 Sem. ( 2 Years ) of Elec. Eng., but then rushed in Soft. Eng. so I'm not an 'Expert' :) When I search this page I cannot find the word 'switching", is this vehicle Pos. or Neg. switching ?
