Tool/software:

Hi team,

As ROM base gauge, it is recommended that external save some parameter in case of pack removing and loss learning data.

I would like to check with you what BQ27426 parameters need to be reserved by MCU when pack remove, in case of SOC jump after new pack plug in?

Hello,

It is recommended to preserve the Ra table and the state parameters.

Hello Kailun,

They are listed in the Data Memory tab of BQStudio and in the device TRM (see below).
