Know of a cheap 24v li-ion to run a boom box?
I've been building boom boxes of various sizes using 24v amplifiers. I can never find medium sized 12v class d amplifiers, so I am forced to used 24v. My favorite amplifier is the tk2050. The inexpensive li-ion cctv batteries I use for my 12v amplifiers can't be used in series because the internal circuitry seems to cut out.
Can anyone help?
Extra points for simple, cheap, light.
Something around 7 Amp/hrs would be great. Maybe under $30.
Oh, and how would you charge it?
