17670 in 18650 lights?

Can you run a 17670 cell in a light designed for 18650 without problems?

I know runtime wont be up to par but it wont damage the cell will it? Even if the emitter is drive pretty high lile 4.2 amps?

I don't have 17670 but I use the protected version of these instead. Maybe you could base your application on HKJ's data.

If you center the cell by making a spacer most lights should work--assuming you have a quality cell like AW. Some high-current lights won't work well with less-than-the-best batteries. I would tend to do this only until I could get a charged 18650 into the light.

I guess my main concern is higher drain damaging a smaller cell. Suposedly a 17670 is a good sub for 2xCR123, most 18650 lights will run on 2-cr123, and thus, a 17670, I would think. Good cells are not cheap and I dont want to ruin my AW17670 protected cells.

That would be fine, as long as continuous current draw does not exceed 2C.

It's allways better idea to carry an extra high quality fully recharged protected 18650
