16
The battery will stop charging if the charging current exceeds 16A.
Overcharge protection
The battery will automatically stop charging after it is fully charged.
Balanced protection
Each battery unit shall maintain voltage balance to avoid overcharge or overdischarge.
Overdischarge protection
The battery will automatically disconnect the power output function when it is not used and
completes the self-discharge procedure. This function is disabled in flight.
Short-circuit protection
The power supply will be disconnected if a short circuit is detected.
Power-down mode
The battery will turn off if there is no operation within 30 minutes.
Communication
During use, the aircraft will be continuously communicate with battery to provide the real-time
information, including voltage, capacity, current, and temperature.
Low power consumption mode
To save power, this mode will be activated when the battery is low and has not been charged for 1
day. After connecting the charger, the battery will resume normal functions.
2.1.5 Intelligent flight control system
Dragonfish Lite is able to conduct stable and convenient flight control by its built-in intelligent
flight control system. This system can support multiple advanced functions, including course
reversal, tracking, terrain following, etc. The working description of each module is as shown in
the table below.

Module
Description
IMU
Use one 3-axis gyroscope and 3-axis accelerometer to measure
acceleration and angular speed. When the flight power switch is turned
on, IMU will calibrate automatically.
Compass
Measure geomagnetic field and provide course reference of aircraft.
GNSS receiver
Receive the GLONASS signal to determine longitude, latitude and
altitude.
Barometer
Measure atmospheric pressure to determine the altitude of aircraft.
