04 Aug 2008 9:52 48 volt charger circuit

Hello friend's
I need some help. This is a 12V Battery charger circuit, when the battery is fully charged the circuit energies the Rally and cut-off the charging volts.
Now I want to use this circuit with a 48Volt Battery Pack (12V x 4 in series). So what can I do to control 48V charging?, or any other circuit that I can use with 48V charger.
Thanks

hi if U want to use this circuit just do these
1- seprate the voltage of charging & opamp supply (or make 12 v from 48 v by voltage dividing or etc)
2- Add a resistor instate of R1 about 82K

note: the opamp just check it's input
pin 2 have 6 v
try pin 3 to 6 volt in 48-50 volt to output terminal

be success
