Main Features:
1. Intelligent Power Indicator 
This product is designed with four high-brightness LED indicators. When discharging or recharging, it can automatically identify the status of the battery.When the battery is in the shutdown status, short press the button,the LED is on for about 2 seconds then go off.

2. Battery Life Reminder
When you use the battery for 150 times, all the LED indicators of the power indication will turn red, indicating that the battery life has been reached.

3. Charging Intelligent Alarm
During the charging process, the battery detects the status in real time, and alerts the charging overvoltage, overcurrent, and overtemperature.

4. Low Voltage Intelligent Alarm
When it detected voltage is low (monomer 3.7V) during the battery in discharge state, the buzzer will alarm. Stop the discharge of battery, the alarm will release.

5. Intelligent Storage Function
When the battery is not in use for a long period of time, it will automatically start the smart storage function, discharge it to the storage voltage, and ensure the battery storage safety.

6. Automatic Sleep Function
If the battery is not in use in 3 minutes after you switch on, it will automatically shut down to save battery power.

7. Software Upgrade Function
The software is upgradable through computer or mobile APP.

8. Data Communication Function
This intelligent battery designed with two kinds of communication method: USB serial port communication and WiFi communication. Through any of them, you can obtain real-time battery information such as the current voltage, current, battery usage times and etc.Flight control can also establish connection with this communication.

9. Battery Logging Function
This battery is designed with a unique logging function that can store all the data on the entire life cycle of the battery. The battery log information includes unit voltage, current, battery temperature, number of cycles, number of abnormal states, etc. The user can use the mobile phone APP to view this.

Product Function and Description
Button Function
1. Turn on: When the battery is off,short press the button, the LED indicates the power. When the light is not off, long press the button for more than 2 seconds, the power indicator lights up from left to right, battery turns on.And the LED indicator shows the current power.
2. Turn off: When the battery is on, short press the button, 4 of the LED on the battery is flashing, then long press the button for more than 2 seconds, the LED indicator lights will be off from right to left, battery enters to shutdown state. 

Intelligent battery indicator
1. This product is designed with 4 red and green bi-color LED lights, indicating the battery level in 8 levels;
2. In the shutdown status, short press the button, the LED indicates the current power, and it will turn off after 2S.
3. In the shutdown status, charge and discharge can automatically wake up and display power, and LED cycle to indicate charge or discharge status;

Intelligent Alarm Function
1.Buzzer and LED are used for alarm;

2. Charge overvoltage alarm:
(1) During the charging process, when it is detected that the voltage of any single cell exceeds 4.35V, the buzzer will alarm with "Di-di" sound and LED2 will flash;
(2) When it is detected that the voltage is lower than 4.3V, the alarm is cancelled, and the LED indicates the power as normal;
(3) Manual shutdown can be performed during the alarm to stop the alarm. After the startup, if the voltage is higher than 4.3V, the alarm will continue until the voltage is lower than 4.3V to cancel the alarm. 

3. Charging Over Temperature Alarm:
(1) During charging, when it is detected that the battery temperature is higher than 75 ° C, the buzzer will alarm with "Di-Di" sound and LED1 and LED2 will flash at the same time;
(2) During charging, when the temperature is lower than 65 ℃, the alarm will be automatically cancelled and the LED will indicate the power normally;
(3) Stop charging, the alarm is cleared, and the LED indicates the power normally;

4. Charging Over Current Alarm:
(1) During charging, if the charging current is detected to be greater than 25A, the buzzer will alarm with "Di-di" sound for 10s, and LED3 will flash at the same time, indicating that the charging is overcurrent;
(2) After the buzzer alarms for 10S, when the charging current is less than 10A, the LED alarm indication will be  cancelled;

5. Low Battery Alarm:
(1) The battery is turned on and is in the discharging state. If the voltage of any single cell is lower than 3.70V (factory default), the buzzer will alarm with "Di-di" sound (no LED indication);
(2) When the cell voltage is higher than 3.73V, the alarm will be automatically cancelled;
(3) Exit the discharge state, alarm is cleared, and the battery will turn off after 3 minutes.

1. Please use a dedicated charger to charge, and away from the high temperature environment;
2. Please charge the battery in time after use, to avoid over discharge caused by long-term storage and damage the battery;
3. When the battery is stored for a long time, due to the self-discharge characteristics of the battery itself, in order to prevent over-discharge damage, the battery should be periodically checked for charging. It is recommended that the single-cell voltage be in the optimal storage state of 3.8V-3.9V.
4. In the course of use, if the battery is deformed or has other unusual phenomena,forbid to use it;
5. In any case, it is forbidden to put the battery into water or fire;
6, Do not extrusion, collision, puncture, dismantling, short-circuit the battery, so as to avoid unnecessary losses.

Due to the high capacity of this battery, we could only use some other shipping method to use it. The shipping price will be higher than usual. The shipping time will be longer than usual.
