I want to be able to monitor the voltage of two 12V lead acid batteries in my system, and have the voltage reading to be displayed on a UI designed on QTcreator.

One way I've thought of is to interface the two through ROS if the battery voltage reader is able to output signals.

Does anyone have any product recommendation or idea to achieve the aim? Thanks.

*Update for those who might be facing the same situation: I'm using a voltage reader that supports modbus communication, and using a python library (minimalmodbus) found on GitHub for the modbus communication. Will be writing a node on ROS to publish the data.
