About the battery life and charging of the Curtain 4 host and extended battery

The main battery of Curtain 4 has a battery life of about 3 months, and the battery life can be up to 12 months after adding an extended battery.

• Test conditions for battery life: 25°C, 3 m track, 8 kg curtain, and switch once a day in standard mode. The actual battery life is affected by operating frequency, resistance, stroke, mode and temperature; the power consumption of the non-sensory mode is higher than that of the standard mode.

In order to ensure charging efficiency and battery life, the expansion battery will maintain the host battery power between 40-80%, and the expansion battery will not fully charge the host battery. When charging, please use a power cord and adapter that supports 5V⎓1A. Please see the table below for charging time and charging light effect.

When the temperature is below 0℃ or above 45℃, charging will be limited to protect the battery.

• Note: If the host battery is exhausted and shuts down, please remove the expansion battery or solar panel first and fully charge the host separately before continuing to use it.
