Features 
1.Over-discharge protection: effectively avoid damage to the battery caused by excessive discharge of the battery                                  
2.Over-protection: Effectively avoid the harm to the battery caused by over-charging the battery                
3.Battery balancing: using electronic technology to keep the battery cell voltage to a minimum deviation to ensure the high utilization of each cell                                      
4.Temperature protection: The thermistor and temperature control processing mechanism are added to ensure that the lithium battery works within a safe temperature range                  
5.Short circuit protection: use active protection technology to automatically protect against abnormal short circuit to prevent damage to the motherboard and battery
6.Overcurrent protection: intelligently detect the input and output current in a timely manner, when the current exceeds the upper limit, actively close the input and output to protect the battery
7.Loss of voltage protection: real-time monitoring of single cells, effectively preventing the unbalance of the battery pack caused by abnormal single cells
8.Waterproof protection: Real-time monitoring of the environmental conditions in the battery pack to minimize the risk of abnormalities
9.Precharge protection: effectively control the capacity repair after the battery is over-discharged
10.Pre-discharge protection: effectively control the impact of the load on the battery
11.Disconnection protection: high-precision sampling real-time monitoring, stop working when the first line is disconnected
12.Positioning protection: GPS and auxiliary AGPS cooperate with each other, please locate accuratel
