Note
A: All the components are distributed on the flexible circuit board, and the battery pack is connected by the circuit board to avoid short circuit due to wire connection or improper connection.
B: The over current protector is an automatic reset safety device set up in the circuit to prevent the occurrence of excessive temperature, excessive current, or both. When the current is cut off, the circuit will automatically reset to a low resistance state.
C: The thermistor is a temperature control device, which can cause the charger to enter a slow state later in the charging process. When the temperature rises to a certain value, charging stops.
D: The diode can prevent the reverse current in the circuit, and prevent the battery from flowing back to the current that is not allowed by the charger during the charging process.
