10s4p unbalanced

Charger stops giving voltage in rebalance mode after 30-200s.

Is this a charger protection triggered ?

💡

Slow progressive current. Valid current is well detected.

💡

Slow drop then rise current. Valid current is well detected.

💡

Current with spike and drop. Valid current is well detected.

💡

No current at all for 5s. Inalid current is well detected.

The battery FSM entered 3 times in Final Balance. Next graphs show data from the charge enter to final balance enter. We see the CV phase, correctly detected.
