I broke down and went to buy a soldering iron at RadioShack today when these batteries caught my eye. 3V 160mAh 1/2 CR2 lithium batteries for about $5 ea. That's 6V with 320mAh about the same as my LiON CR2's but more Voltage!
I started wondering how I could use a pair of these to pump 6V through one of my CR2 lights like the NEOCA, JIL DD, RAW, or others.
What do you all think might be the proper bin/VF to run in this setup if any?
If possible, what about the bin/Vf of a 5W LED?
Any comments on heat, runtime? Is there a sag issue or is that just an incan issue?
