Hey Wayne:
I have a question. Since the Li-IOns start at 4.2v off the charger, and I remember seeing soemthign that says the LED goes into direct drive over a certain voltage, would I be damaging the LED's useful life byh using a Li-ion battery? I would like to use the NexGen 750 in a MMM Mag witha 14720 battery but am concerned on the effect it may have on the life span of the LED.
