III. Function Description
1.Intelligent battery level display: The battery is designed with four LED
lights that intuitively indicate the current battery level.
2.Power-on self-test function: The battery performs a self-test every time
it is turned on. When the voltage difference between the battery cells is
greater than 200mV, all four red LEDs will flash 10 times, accompanied by a
buzzer alarm to remind the user of the battery's imbalance and the need for
balancing maintenance.
3.Automatic sleep function: When the battery is turned on but not in use,
it will automatically enter shutdown mode after 3 minutes without the need for
manual operation.
4.Intelligent maintenance function: When the battery is severely imbalanced
due to special reasons, the user can manually activate the intelligent
maintenance function to balance and maintain the battery, achieving good
balance performance.
5.Intelligent alarm prompt: The battery uses a combination of buzzer and
LED alarms to alert the user of abnormal battery conditions, such as
overvoltage, undervoltage, overcurrent during charging, and over-temperature.

6.Data communication function: This battery has both serial communication and
Bluetooth wireless communication capabilities. Both communication methods can
provide information on individual cell voltage, total voltage, current, state of
charge (SOC), temperature, cycle count, and abnormal status count. It can also
establish a data connection with the flight controller via serial port. Bluetooth
7.Intelligent log recording: The management system has a unique log data recording
function, continuously monitoring and recording battery information, including
individual cell voltage, current, battery temperature, balancing records, cycle
count, and abnormal status count. Users can query the information by date and time
using the upper computer software, or export historical data records in Excel
format.

ingle cell exceeds 4.30V, the buzzer will sound an alarm and the corresponding LED w
ill flash (pressing the button will stop the buzzer alarm). The alarm will automatic
ally be released when the voltage drops below 4.25V.
(2) Battery low-voltage alarm: when the voltage of a single cell drops below 3.00V,
the buzzer will sound an alarm and the corresponding LED will flash (pressing the bu
tton will stop the buzzer alarm). The alarm will automatically be released when the
voltage rises above 3.05V.

V. Safety Tip
After connecting the power output cable of the battery to the power input
interface of the drone, the drone can take off normally. If there is
communication between the battery and the flight controller, you must perform a
startup operation and wait for the data communication to be normal before
taking off.
⚠Warning:
1. This battery is designed exclusively for use with unmanned aerial
vehicles and does not have any discharge protection functions such as over-
discharge protection, over-current protection, over-temperature protection, and
short circuit protection. When using the battery, please pay close attention to
the low battery warning information provided by the unmanned aerial vehicle and
return in time to avoid damaging the battery or other losses caused by excessive
use.
s
To ensure maximum safety in use, please follow these guidelines and use the
(3) Over-current alarm during charging:
battery correctly according to the operating instructions. Failure to do so
may result in permanent damage to the battery and its surrounding environment,
and may even cause personal injury.
