The default senc comes from the IC has the hidden constant = 0. You can do the following to recreate a good senc file:

1. Extract the dataflash image from your current senc file (use bqEASY to read out a dfi file). This will reserve all your DF configuration, calibration data, chemistry, learned R/Qmax (if you done a learning cycle).

2. Download the default senc file from the device product page (under "Tools and Software"). Program it to a device
