Turn on the Lithium Battery Power Switch

Charging
The Meshtower comes with preconfigured battery management settings. Once connected to an 18–24V solar panel or a USB-C PD3.0 (20V) power source, and with the antenna properly installed, the device is ready for operation.
However, before first use, it is recommended to connect an 18–24V solar panel or a USB-C PD3.0 (20V) power source to activate the battery function, and fully charge the built-in battery through the USB-C port or DC power interface to ensure more stable power delivery and optimal performance.
Before charging the device, make sure the battery power switch is Turned on.
Via USB-C(recommended)
The USB-C port requires PD3.0 and a 20V voltage input.
Via DC
The DC interface is the solar panel input port, which uses an XT30 connector and supports an input voltage of 18-24V.
Checking Battery Level
- You can check the battery level via the Meshtastic app on your phone.

- You can view device-related information through the serial port in the Meshtastic client.
