hey, I just took apart an old battery backup surge protector that's battery side wasn't working. I'm assuming it was just a fuse or some other part, as the battery still has a monsterous charge.
I got a really nice 12 volt 4ah/20hr rechargeable battery thats only a little bigger than one of those 6 volt lantern batteries. My question is how did they up the voltage in the circuit to 120 for when power goes out? Did they use a Step-up transformer?
I'd like to make a sort of inverter, kind of like what they use to up the voltage from a car battery to AC 120 for running appliances.
What I would really like to do is only up it to 32 volts @ 2 amps or 40 volts @ 1 amp so I can use this in a 50 watt guitar amp I am building. I also would like to know how to build something to charge the battery with.
So Is this possible? If so, how?
Thanks for any help!

You can use one of Switch Mode Power Supply methods, but this is off topic here. Try to visit Power Supply Design part of DIY Audio.

mm... I didn't see any inverter circuits there..
All I need to do is convert 12 vdc @ 4 amp hrs to 40 vdc @ 1.2 amps or so.
btw, how do you convert DC to AC ?
