The simplest way to do that from a single cell is use a single cell class D amplifier. I thinks these are available on Aliexpress and others. "single cell" ? Is that like the one I linked above, and also this Chinese "knock-off":   https://www.aliexpress.com/item/4001137950571.html I think my final build is just going to look like a bunch of off the shelf Aliexpress SMD modules ... I suppose you then work out what individual components they have on them and design a PCB for JLPCB (other services are available) to populate. Best wishes, Tom
