Protection features

1. Ultra-low frequency composite pulse charging: preventing the sulphation of new battery, removing the sulphation of old batteries and the concentration polarization of battery.

2. Intelligent temperature compensation function in the charging process, preventing the damage to battery caused by change-off or charge due, greatly extending the lifespan of the battery.

3. equalized charging: Extend the lifespan of battery packs.

4. Short-circuit Protection: When the charger encounters unexpected short-circuit, it will automatically close charging. When fault is removed, the charger will re-start in 10 seconds.

5. Thermal self-protection: When the internal temperature of the charger exceeds 75°C, the charging current will reduce automatically. If it exceeds 85°C, the charger will shutdown protectively. When the internal temperature drops, it will resume charging automatically.

6. Reverse Polarity Protection: The charger would automatically cut the connections between its inner circuit and the battery when the reverse polarity happens, the charging will not be started, and therefore no damage would be happened on the battery and the charger.

7. Input low voltage & Overvoltage Protection: When the input AC voltage is lower than 180V or higher 265V, the charger will shut down protectively and automatically resume working with the voltage is in the normal range again.
