The above driver has this statement with it:

“Low voltage protection 2 cells: at 5.8V the light will step down to low mode and start flashing”

Wouldn’t the above driver interpret 4AA’s as 2 Li-ion’s and step down once voltage sagged to 5.8v?

You are correct.
Its the LD-29 driver. I mentioned it in OP.

I have now shared my findings with the 3-18V driver i mentioned in OP too. you guys can now read about it here.

I can only comment on the 105C. I use 4 Enelopps with them all the time and I prefer 4 over 3. I know about excess voltage and heat, but really, when you want to push 3-4 amps I think the excess voltage is not an issue since the batteries will sag. From the results I have seen, the 105C@ 3-4 amps works better with four NiMHS than it does with 3 NiMHs. Output is closer to expected. Especially since I usually add a couple more chips and am closer to 4 amps than 3 amps.

Thanks Justin… That have been my thoughts too…
Im just thinking that when you run it on say, low, you will barely have any voltage sag at all. So with freshly charged batteries the driver would get up towards 5,6V (1,4*4). That is way above the rated 4,5V. And the LED would only need around 3V. But I as others have mentioned, I believe those drivers should take 6V max. And with a very low current I would assume it would be no issue. Except quite low efficiency.
But do you (or others) have experience with it? Basically, reliability when used for a longer amount of time on low or medium with freshly charged batteries.
