Pet GPS devices face multiple challenges in practical use: devices are prone to drops due to human factors, and intense jumping of large dogs, fights and bites between pets, and other behaviors can all cause impacts on the devices. To address the above issues, our company has conducted specialized optimization design for the 4.45V, 2500mAh high-voltage battery. This battery has undergone rigorous testing, including 10 simulated drop tests from 1.2 meters on different surfaces and strict roller tests. After the tests, the battery remains intact with no impact on its performance, ensuring stability and safety during use.
