I need a charger circuit that can charge a 6 volt NiMH battery pack and supply 1.8 amps while charging. Can somebody please make me a schematic? I have looked everywhere and found nothing. If you're curious, I am making a rechargeable soldering iron that needs to be powered off of a transformer when the batteries die. I would like the transformer to also charge the batteries while powering the iron.

 

Are you trying to do this yoursel and learn, or just looking for someone to do the work for you?

 

I did a google search on "nimh battery charger schematic" and got more responses than I could go through in a lifetime. Now, did you really look everywhere?

First off..ask ur self, can a 6V cell power a soldering iron ?

 

I have the basic circiluit. I just need some guidance on how to regulate the charging of the batteries.

 

Show us what u got so we can help.
