Context,
I live in rural Swaziland and have little access to things, and very low funds, I am using this project to teach kids at an orphanage how to plan, purchase and solder an electronics project.
The basis for the project:
I have a busted desktop speaker set that I want to transform into a battery powered speaker set. I have a friend coming from the US soon that can bring me a couple of small items from amazon.
What I want to achieve:
Be able to run the speakers from mains or battery
Connect and play via bluetooth (aux would be a bonus, but hardly needed)
Have a volume knob.
Supplies on hand:
24v 2a power brick. Could probably find a 19v laptop psu if needed.
12v2.2ah Sealed Lead Acid Battery
2x 5w 4ohm drivers
3x dual potentiometers from the busted speaker set. (originally Volume, Treble and Bass)
Questions:
Would this board be suitable for driving the speakers, and can I solder on my own POT for the volume control.

What charging board can I use, that could work with the 24v 2a supply?
Does anyone know if this board would have the characteristic ground loop noise, and is there a way to mitigate it?
