I can’t wait for this to happen. I haven’t had an AA light in my pocket for a while and that will change if it supports NIMH. I know it’s too soon to speak of but I hope you can get Lumintop on board with this as well.

Still interested!

Still interested as well… :sunglasses:

I’ll have one

MascaratumB,

Boosting the voltage from a NiMh to usable levels for the LED is a bit rough. The NiMh cell will have voltage sag when we ask higher currents of it, so we end up boosting from ~1V up to 3.5-ish or so for the LED. If we wanted to drive the LED at 1A, that's easy for a Li-Ion 14500 cell to do, but from the NiMh cell we're suddenly asking for something like 3.5A from it. The alkaline will already have given up, but quality NiMh will hold up to this for a bit. Just not very long, as that's over 1C discharge, with voltage falling fast. The more the voltage falls, the more current we need to get our power output (because Watts = Volts*Amps).

I used to rebuild NiCd/NiMh tool batteries, and there are some cells out there that I wouldn't mind subjecting to that kind of abuse, but they are all larger than AA size. Eneloops are good, and can discharge surprisingly high drains, but the voltage is too much of an issue.

Interested, but I’m concerned about how Anduril will be ported for a boost driver, and of course the associated problems with boosting a NiMH/Alkaline.
I see myself using this light normally on 14500, where I would wish to have a max of ~600 lumens. But in case of emergency, it would be nice to also be able to run off of a AA/NiMH, where I wouldn’t want 600-700 lumens anyway to conserve power. I’d be fine with a max of ~100 lumens, which all chemistries should be able to handle.

Interested.

How did Wuben the magic in its E05(-I)? It runs on NiMH the same modes as on 14500, except turbo. Is this a matter of efficiency?

sounds good to me, interested for sure

Would it be possible to limit the power of the flashlight when running on NiMh on the basis of max optimal load for that cell chemistry? Unsure if that would be easier or harder

Interested

This is mandatory.

Only just realised I haven’t explicitly expressed my interest. So… interested!

Very interested if the light comes with a lighted switch or dim indicator light (or is easily modded to have one)

Dual chemistry would be great to see!

Interested if it comes with nimh support and anduril
