             3. Protection Functions

                Over‑temperature Protection:

                When the internal temperature exceeds 80℃, the charging current will decrease automatically. 

                It will shut down for protection once temperature hits 85℃, and resume charging automatically after temperature drops.

                Short‑circuit Protection:

                The charger cuts off output upon output short‑circuit. Charging will resume after fault removal and battery reconnection.

                Battery Reverse‑connection ProtectionInternal circuit disconnects automatically when battery is reversely connected. 

                No charging will occur and the charger will not be damaged.

                 Input Under‑voltage & Over‑voltage Protection:

                 The charger shuts down for protection if input voltage is lower than 150V or higher than 264V. 

                 It will restore operation when input voltage returns to normal range.

                 Auto‑stop When Fully ChargedAutomatically power off upon battery full‑charge completion.
