Hi!
I'm building a boombox where I have 10, 1.2 Volt AA rechargable batteries in series (12 V total) and I was wondering how I can charge them while still using the boombox and to prevent overcharging, do I need a voltage regulator between the amplifier and batterypack so that I don't go over the amplifiers threshold or do i need to do something else so that I don't completely destroy everything,
I know that I can add a few switches so that the battery disconnects when hooked up to the wall, but I want to make the boombox as user friendly as possible.
The amplifier I use takes between 8 - 25 Volts (link further down)
Amplifier:
