CEDV parameters resulting from the fit. If EDVV bit is set to 1, EMF and EDVR0 have to be multiplied by the number of serial cells when written to data flash

EMF 3157
EDVC0 253
EDVC1 0
EDVR1 1045
EDVR0 885
EDVT0 4991
EDVTC 11
VOC75 3866
VOC50 3663
VOC25 3554


Recommended SOC deviation tolerance at EDV2 point is < 5% for low temperature and <3% for room and high temperature

Deviations for this set of parameters are given below for each file
