      Features

      1. Overcharge protection: When a cell reaches overcharge voltage, the board shuts down the charging circuit to prevent overcharging.
      2. Over - discharge protection: If a cell's voltage drops below the set limit, the discharge circuit is cut off to avoid over - discharging.
      3. Short - circuit protection: In case of a short - circuit at the output, the discharge circuit is immediately shut down for safety.
      4. Discharge over - current protection: When the current exceeds the limit, the discharge circuit stops to protect the battery.
      5. It has a 15A working current, high - accuracy voltage detection, secondary over - current protection, and low static current for energy savings.

      Application

      This model is small but powerful and can be used for various small appliances such as electric drills, shavers, smart trash cans, electric razors, etc.
