     I run rel-des-rel cycle on BQ27510evm...

    Is there any issue with the log file i generated  ?? As of now i am not able to proceed further.

    In mathcad worksheet I am getting Qmax/3.6 as 1466mah, all other curves are plotted  but when it comes to best chemistry ,variable unidentified message is displayed .

    Is this becoz there is no chemistry ID that match my discharge pattern?? Am i making some error??

    I did the rel - dis - rel cycle on a fully charged battery so the charging data captured in the log file is limited. Does that mean  thet my rel - did - rel cycle wrong??
