Just a quick question for those more knowledgable.
Is it possible to modify a protection circuit on some Ultrafire DX Li-ions to act as an adjustable current limiter for a otherwise direct drive led?
Alternatively, is there any circuit which can sit between the -ve pole of the battery and the -ve pole of the led only and limit current? This would be my holy grail of LED drivers as I could integrate a pot in the back of my flashlight without additional wires.

. The switching has to be between the battery and the driver.
