1. When lithium battery is used, the system voltage can’t be identified automatically.
2. At minimum operating environment temperature.
3. At 25°C environment temperature.
4. When lithium battery is used, the temperature compensate coefficient must be 0, and can’t be changed.
5. The controller can supply full load working in the environment temperature. When the internal temperature reaches 81°C, the reduced charging power mode is turned on.
