Hi,

In this post : it's more or less recommended to leave at -400mA.

But do you have a calculation to recommend to correctly determine the value?

For information, we chose -20mA thinking that the FCC register will be updated at the slightest discharge.

Is it correct ?

Hi Charles-Elie,

The default is -400 mA. It is recommended to set this value to a typical system current.

Sincerely,

Hi Bryan,

Ok, but can you give me more information about this register? What is it used for ?

Hi Charles-Elie,

I apologize, this post slipped through the cracks.

The State of Health Load is used by the StateOfHealth() command to calculate the SOH percentage (among other variables). Please set the the SOH Load to a typical system current. For more information, please refer to section 7.3.2.10 of the Datasheet.

Sincerely,
Bryan Kahler
