Hi, So for this circuit I am still confused about the LED. So using this to charge a  battery, would the circuit also act as a type of charge cutoff, meaning if the battery is fully charged would the circuit stop charging the battery? If so, are we able to change the thresh hold for the cutoff?

Also could you give more details on the PWM part for this circuit? Not sure what it would be used for.

 

ThanKyou!

Hello Neil,
Thanks for writing in.
Are you talking about the above item #090482?
It can’t stop charging automatically. The above circuit diagram is to prevent battery from feed back and damaged item.
In generall, PWM terminals doesn’t need to be hooked it up. It is connected with microcontroller to control output and adjust current.
Best regards.
