Hello,
i found this circuit fo a 12v lead acid battery charger but is for
12v, i was wondering if anyone here knows what part i must change (i am
sure the transformer must be replaced to 24v) in the circuit in order to
make 24v charger.....

thanks!!!!!!!!!

Change the 5.6K resistor at the bottom right to 2.2k.
