:confused: Hello All,
Could you please help me out wit a problem. I have built 4 of the SH designs charger witht eh variable voltage and current and LED indicator. This is the one that can charge one - three cells and can go frm 10mA to 1.5 amps charging current.
Problem is , I am not able to get the current under 280/300 mA. It changes up to 1.5 amps. but no matter what i do , it does not fall below ~300mA. its supposed to give 10mA with R4 being 47 ohms. but it still gives 300mA. I tried with a 470 ohm resistor and it still gives ~ 300mA.
Any suggestions ideas ?
thanks a lot in advance for all the help
