Hi @SimoneMic, I investigated the problem yesterday.

Probably, the battery was accidentally forgotten switched on over the weekend which caused the battery to discharge completely.

The BMS (the battery control board) sent the battery into undervoltage protection and so to restore the battery functioning, I connected the charger directly to the battery in order to charge it to the minimum amount needed to overcome the undervoltage threshold.

Now the battery is charged and working properly. Closing!
