hi everyone, newbies here... i just want to convert 12V DC (battery cell - like the one use in car batteries) to 24V DC but using a circuit... i had viewed http://www.aaroncake.net/circuits/12VDC_To_24VDC_Converter_Circuit.asp?showcomments=all, but i don't know if it will work... we tried a series 12V, but need circuit/converter to use it... please help, thanks a lot
