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.
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. And the shipping time will be longer than usual, shipping will be more expensive, we may contact you if the shipping our website charged is not enough.
