Smart Battery Functions
The smart battery has the following functions:
 Battery Level Display
The smart battery has a built-in battery level indicator, which shows the current battery level of
the smart battery.
 Self-heating
This function allows the smart battery to operate normally even in low-temperature
environments, ensuring flight safety. For more information, see “5.3.3 Smart Battery Self-heating”
in this chapter.
 Communication
The aircraft can obtain real-time battery information, such as voltage, current, battery level, and
battery temperature, through the communication interface on the smart battery.
 Power Saving Mode
The smart battery will automatically shut down after 5 seconds of inactivity to reduce power
consumption.
 Dust and Water Resistance
When correctly installed in the aircraft, the battery has an IP43 protection rating.
 Ultra-low Power Mode
When the smart battery is idle for 24 hours and the battery level is less than 8%, the battery BMS
will enter the ultra-low power mode to reduce self-consumption. When entering ultra-low power
mode, it needs to be activated by a charger before it can continue to use normally.
 Self-discharge Protection
If the smart battery is stored in a high-temperature environment or not used for 6 days with a
high battery level, the self-discharge protection will be activated. The smart battery will
automatically discharge to a battery level of about 60% (by default) and the discharge process
takes 2-3 days.
Tip

Although the battery has no indication of a self-discharge cycle, you may notice that the
battery is slightly warm, which is normal.
 Sleep Mode Protection
If the smart battery has a low battery level, it will automatically enter sleep mode to prevent
over-discharge. In this mode, the smart battery does not respond when the power button is
pressed. To wake up the battery, you can connect it to a battery charger.
 Charge Temperature Protection
The smart battery will stop charging when its temperature is lower than 10℃ (50℉) or higher
than 40℃ (104℉ ) during charging, as charging the battery under such temperatures will
damage the battery.
 Overcurrent Protection
The smart battery will stop charging when the charging current is too high, as charging the
battery with a high current can severely damage the battery.
