Protection Features

Burnout Protection

When the internal temperature of the charger exceeds the internal setting value, the charging current is automatically reduced; when the ambient temperature exceeds 65°C, the charger will automatically shut down for protection, and when the temperature is restored, charging will be automatically resumed.

Protection for Reverse Connection of Batteries

When the battery is connected in reverse, the internal circuit of the charger will disconnect itself from the battery, and the charger will not be damaged.

No-load Protection

No output when no battery is connected.

Short Circuit Protection

When the output short circuit occurs, the internal circuit of the charger and the battery are disconnected, and the charging can only be resumed after the fault is eliminated and the battery is reconnected

Automatic shutoff when fully charged
