12v 20 Amp Battery Charger Circuit Diagram

So i use a 2a 12v transformer in the unregulated power supply.

12v 20 amp battery charger circuit diagram. Thank you for these interesting circuits i am in the process of building 12v charger using ic l200but am finding it difficult to calculate rx and ry. Once we attach the charger with the battery voltage drops from the actual supply 14 2 v level to the discharged level of the battery. It can be used to charge 12v batteries. I use it for 12v 7ah battery and lower.

The working of the circuit is as. The ah ampere hours of each battery may vary based on the required capacity a 7 ah battery for example will be able to provide 1 amps for a duration of 7 hours 1 amps 7 hours 7 ah.
