If I have a 4W transformer that has high inductance, thick windings, (4V ,1 A) and converted to DC via a rectifier, in order to charge a lithium ion battery (low internal resistance) ,
will the output will still be slightly less than 4V or will it be very low (close to 0 which makes it impossible to charge a battery) because the battery load has so little internal resistance?
Has anyone tried that before?
