Temperature Warning Fault

When the low/high temperature icon appears, it means the internal battery temperature is too low/high. As a protective measure, the device temporarily disables charging or discharging. 

Please follow the steps below: 

1. Move the product to a warmer indoor environment (recommended room temperature: 15°C–25°C), avoiding direct sunlight or placing it near heaters.
2. Wait for a while (typically 2 hour) until the low temperature icon disappears automatically.
3. Once the icon disappears, try charging or discharging the product again.
4. If the icon does not disappear for a long time, try restarting the device and test again.
