I've got a couple Maglite 2D LED flashlights. They're prior to the current generation, these have the Rebel LED in them. I've been wanting to use eneloops in it, but I want more than two, for more than 2000 mAh.
I've seen plenty of adapters that put two AA in parallel in a D size shell, but that's still only two in place of each D. Ideally, I'd like to get 6 batteries in there, a 2S3P arrangement (2.4V nominal). No one makes an adapter that puts 3xAA in one D, in parallel, at a viable price point.
I have a couple carriers from some old rayovac ubercheapie plastic LED lights that hold 6xAA in a 3S2P arrangement (3.6V nominal). This gets a full 6 cells in the light, but with the higher than standard voltage. Is this going to fry the LED?
If it doesn't fry something, will it be brighter at this higher voltage, or will the driver reduce current, and it will instead have more runtime?
