Hello,

I want to supply my St Iot discovery kit board with a battery supply, I have changed the header pin to 5V_VBAT. As i am connecting my battery to the Vin and gnd pins the red LED keeps blinking and LD5 is off. 

Kindly give some suggestions how should I fix this.

I am using a 5v rechargeable battery for this, can I use a 9v battery for the same or it will damage the board ?

Hello @Arhum_29 

I suggest you to take a look at the part 7.4 of the UM2153 where you can find more details about how to supplie your board.

Best Regards.
