You can write a simple suscriber ( you can follow this tutorial ) that will suscribe to your battery state topic.

In the callback function you can access and display the voltage (for example) using msg->voltage . All the parameters you can access to are available here .

You will find how to write a simple suscriber in python here. I don't know the name of your topic but I am pretty sure you can find it using the rostopic list command when your robot is awake.
