GPS Battery Safety Features
1. Abnormal Temperature Alarm: Real-time battery temperature monitoring. If the temperature rises abnormally, the app issues an alert, allowing for timely intervention to prevent and mitigate fire risks.
2. Remote On/Off Switch: Remotely control charging and discharging. The charger automatically cuts power once the battery is fully charged; additionally, you can use the app to remotely stop charging (the physical switch on the battery controls power flow, while the app offers remote control—providing a dual protection).
3. Real-Time Data Monitoring: Unlike traditional battery displays, the GPS battery app provides highly accurate data readouts: voltage, current, temperature, cycle count, usage duration, mileage, and recorded riding routes.
4. Multi-Language Support: English, German, French, Spanish, and Italian (customers from other regions should ensure they are able to read at least one of these languages).
5. Flexible Account Management: A single mobile account can be linked to multiple batteries for convenient management, while each individual battery can be linked to only one mobile account. This ensures a secure, convenient solution suitable for a wide range of usage scenarios.
6. App Service Fees: The first year of app service is free. Starting from the second year, the annual subscription fee is 20USD. If a customer chooses not to renew the subscription, the battery will continue to function normally, though it will no longer be able to connect to the app.
