voltage controlled switch

[chukwumezie]

I need a voltage controlled switch that will switch off a battery charger when fully charged; charging a 12v-200AHr battery. I have built the charger but a can't controll it when it is fully charged; it just keeps on charging; thanks

Post your schematic.

There have been many Automatic Charger circuits discussed on these forums in the past year. I have posted some schematics.
