Tips：
A. In order to prevent the battery from over-discharging, the battery will sleep when the
battery level is less than 10%. At this time, the charger cannot be charged automatically
when it is plugged in, and the battery needs to be turned on manually to charge.
B. If the battery temperature exceeds 55 degrees Celsius, the battery high temperature alarm
will be triggered. You need to wait for the battery temperature to drop below 55 degrees
before charging.
C. In the fast charge mode, in order to protect the battery and prolong the battery life, the
single-chip cell voltage stops charging at 4.15. At this time, the battery power does not
reach 100%, and the battery indicator may flash LED4, but it does not affect the battery
life.
D. E. If the battery is not used for more than 5 days in a fully charged state, in order to extend
the life, the battery will automatically discharge to a safe voltage for storage, and the
battery temperature may rise during the discharge process.
E. If the battery is not used after it is turned on, the battery will automatically shut down
after 10 minutes.
APP Battery Management (Only Available in China Mainland）
If using a charger with 4G network function and adding a charger,Users can view the battery
history and real-time statistics of the connected or connected charger in the AGRAPP
Application Scenario:
When you need to count the number of abnormal batteries of all batteries under the user name；
Battery level when last minute online ；the number of cycles and other information, Users can
quickly view, count, and manage the battery through the battery management function; It is
convenient for users to quickly candidates abnormal, fully charged, need to charge, over-charged

and other status of batteries, reducing the workload of battery management.
View Steps : Open AGR APP——Click the user information icon on the main
interface ——Click on my battery to enter my battery interface so as to filter and view the last
online power and cycle times of each battery.
Click the button of the battery you want to view on the My Battery screen,You can enter
the history usage of the selected battery. In this interface, you can view the data information of
each history usage of this battery.If there is any abnormality, you can filter out the abnormal time
period of the battery.
On the battery history interface, click the button to view the time period,You can enter the
battery usage details interface for the selected time period of this battery.In this interface, you can
filter the abnormal status every few seconds and view the voltage of each cell every few seconds.

Plant Protection Platform Battery Curve Analysis
（Available in Mainland China only）
If using a charger with 4G network function and adding a charger,You can view the battery charge
and discharge curves on the AGR plant protection platform,The graph can analyze the battery
voltage, current, pressure difference, temperature and other information intuitively and quickly,
which greatly facilitates the analysis of battery failure.

Battery Use of Caution
1. Never disassemble the battery
2. Never put the battery into water or fire.
3. Please use special charger to charge and keep away from high temperature environment.
4.Do not Use batteries that are damaged,leaking.
5. It is forbidden to squeeze, bump and short-circuit the battery, so as not to cause unnecessary
