Adding a volt meter?

Is there an easy way to add a voltmeter to this project so you can tell how much charge is in the battery?

Yes. All you need to do is connect the voltmeter to the positive and negative battery terminal.

Simply connect a basic voltmeter, such as the one below, in parallel with the boost converter. That way, when you turn on the charger, the voltmeter will turn on and display the voltage of the battery.

It won’t display the battery voltage under a load.
