Hello everybody, I need your help.

My Makita 3Ah - 18V battery stopped working out of nowhere. When I put it in the charger, the green and red lights flash alternately, indicating there is a problem.

However, the battery is practically brand new. I have a feeling it got locked/blocked, which is why I'm uploading this photo so you can please help me with the circuit board shown in the images so I can replace it since I haven't found it anywhere...

Thank you a lot in advance.
