Deal fellows,
I have encountered a problem while designing BMS for 8s20Ah LiFePO cells from Tenergy.
I have updated the chemistry in device flash (for 431), but CEDV cfg parameters has not changed and remain at default values fitting Li-Po battery. What is more, in chemistry tab of bqStudio, under "Update chemistry in data flash" button, there is text stating "Cemistry Version : 369"; and it remains like that after successful chemistry update.
I can read CHEM_ID from bq78350 and it is 0x0431.
Is there a way to obtain CEDV Cfg parameters from chemistry data, or it is always required to perform experiments at various loads and various conditions to determine them?
Last but not least - the "uptate chemistry" command from help menu does not work - is there any particular reason for it?
