The operating temperature of the TB60 Intelligent Flight Battery is -20°C to 50°C. When the battery is used in a low-temperature environment, note that the battery life will be reduced. To optimize performance in the cold, it is recommended to warm the battery up to 15 °C before use.
When charging the batteries in an environment between -20 °C and 5 °C, the self-heating function will be activated to raise the battery's temperature to above 5 °C.
Once installed on the aircraft and the power is turned on, if the battery’s temperature is low, it will automatically self-heat to keep the temperature at about 16 °C to 20 °C.
