Need Charger For Amp (v12)
I have an old set of computer speakers that run on 12v dc, I ripped it out and set it up in a radioshack enclosure with 2 9volt batteries connected to a cut-off power cable that fit the main board. (I realize that the 2 9volt batteries are over the 12v mark but its needed because with only the single 9v battery it cannot handle my cardboard box sub-woofer)
I want to take 2 rechargeable 9volt batteries and wire them within the case (because unscrewing the case and taking the thing apart sucks to replace batteries) and I have to be able to charge it by pluging it into an outlet.
I have moderate soldering skills and work with electrics often although I dont often use high voltages like 120ac wall current :) Can you guys help me out?
