I need schematic of a 6v 20amps Lead Acid smart Charger

[Khaleef]

I would like to build a 6V 20amp charger for my  6v 200ah Battery so I can balance charge them before connecting to a converted UPS to use as an Inverter. I would like a smart charger that can regulate the current supply as the battery charges up. I hope to get a schematic I can put together to achieve this.

Thanks.

I looked around for such a charger, but seems difficult to find a suitable circuit for such high current output.

Let see if someone can come up with a schematic.
