G giannishalkida New Member Feb 28, 2012 #1 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!!!!!!!!!
