Hello Neil,

You do have the BAT pin connected correctly, since you have it connected to BAT+ pin. Also BQ27427's SRX pin is connected correctly too, but to clarified where is your load connection points are?

Thank you,
Alan

Hello Neil,

-This is a charger E2E question please reach out to them for clarification

-This is done correctly

-On the battery gauge end this is correct, but on the charger end I would ask for clarification to make sure that this would carry the load

Thank you,
Alan
