                CharacterA characterA = theCollider.GetComponent<CharacterA>();
                this.watt -= characterA.watt;
                if (characterA != null) {
                    for (int i = 0; i < listeners.Count; i++) {
                    }
                        listeners[i].OnBaterryPluggedOut(this, characterA, characterA.watt);
                }
            }
            catch { /*On error do nothing*/ }
        }

i want to get the value var watt and assign to tott.. (tott = watt)

C#

public class Second2 : MonoBehaviour {
        private List<ISecondListener> listeners = new List<ISecondListener>();
        public int tott;
    
        public void cek (){
            tott = watt; /* <--- how i can get the value from var watt at class First() to var tott?? */
        }

You can't - Second2 and MonoBehavior do not contain a variable called watt and the only class that does (First1) is not related to Second2
Instead, derive Second2 from First1 rather than MonoBeahviour:

XML

public class Second2 : First1 {
        private List<ISecondListener> listeners = new List<ISecondListener>();
        public int tott;

        public void cek (){
            tott = watt; 
        }
