Hi,

I would like to keep "CC Delta " and " Remaining Capacity" values after calibration.

Currently, this values are reset after diconneting the battery from the gauge more than one minute.

How to avoid the gauge data reset ?

thank you

Bernhard,

The Remaining Capacity is a calculated parameter that is not stored in flash, but the CC Delta is stored in flash and should not change after a reset.

Regards
Tom

Hi,

Thank you for your previous answer.

What is the max voltage on the pin "RBI" of BQ2084 ?

Regards,

Thibault

You normally just place a capacitor on the RBI pin, so I am assume that you want to apply an external voltage. In that case the RBI voltage should be set to 3.3V typ, 3.6V max and 4.1V absolute max.
