The battery display will show an E0 error code when the battery is powered on but not connected to the Jet unit.
a. Turn off the device.
b. Connect the Jet to the battery using the connection cable.
c. Turn the device back on and check whether the error disappears.
2. Check the connectors and ports for water or moisture.
Water remaining inside the connectors or ports may affect communication between the battery and the Jet. If any, dry the connectors thoroughly before reconnecting.
If the issue continues, please provide:
