Transforming a speaker from AC to battery Answered
I'm trying to turn an AC powered speaker into some sort of boombox aka run on battery and add bluetooth.
The problem i'm facing is that I'm unsure of where to hack the battery in since the circuit rectifies on-board. My best guess would be to just start probing the terminals until I find a stable power. I also think I have to bypass the 2 transformators (see bottom). But before starting I wanted to see if there is anything I should watch out for, since I don't have too much experience with Li-ion batteries.
Any thoughts, advice, prayers are welcome!
