Can I replace 5v battery to 7v battery in an amplifier circuit?

This project is an amplifier board. In this project, I used 2*100w,2*50w,2*25w TDA7498E Class-D audio amplifier board series.
I used this TDA7498E in a test circuit stereo application and mono BTL mode. I also used the 5v battery in this project. But it seem that it has no function in this circuit . I was confused and I checked everything is ok. Is there possibility of the battery problem?

Looking at the datasheet, there is an undervoltage protection at 8V, and the power supply range is 14 to 36V. So it is unlikely that it will operate at either 5 or 7V battery power.

Now i used to think that i was cool,
drivin' around on fossil fuel,
until i saw what i was doin',
was drivin' down the road to ruin. --JT
