I tested these cells at 1A on a CBA-II but the graph is at home, I will post the graph later today.

with a fresh charge they should definitely hold 3.6-3.7V up to 1C (1.4-1.6A).. they will not 'hold' 4.2V with anything over like .5C and you will likely get up to 3.8-3.9V for a few minutes before it settles in at 3.6-3.7V/cell.. i'd love to see the graph can't wait

Here's the AW17670 graph at 1.0A.

thanks that's very nice.. it does 'droop' a little more than i remembered but the 3.45 'dead bat' value showed up more like 3.4 in this plot.. but it does look like what i remembered basically.. i did my testing with tiny batteries though (aaa)..

Thanks! Too much wasted space below 3.0V. I'll redo it later on today.

Would this also apply to Pila 168/150 batteries?

the 168 should be a little stronger, the 150 a little weaker, but very simlar. I have noticed a little less output from the PILAs than the raw cells which makes sense.. i seem to remember numbers like up to 80mohm from the protection ckts.. 0.080ohm.. doesn't seem like a whole lot, but it does make a difference.

I'm thinking about a mod to a 10W HID I've got that runs on 4xCR123s and I've read that 3xR123s work too. I've never used those but I've got a bunch of Pilas so I was thinking about a mod to the 10W HID using those. It would be similar to a Wolf-Eyes Dragon I methinks.

You would be overdriving that ballast pretty hard if it's the standard WA 10.2v ballast. There are regulated holders that provide 11.4v constant but during the initial 10 minutes or so you would be higher than that. Most people consider 11.4v the max to overdrive this ballast. I may try it though what the heck there rated for 1000 hours so what if we only get 500
RCR123 cells drop more voltage under a 1amp load than these bigger cells.

So what ballast do you suppose is in the Dragon? Is there such a thing as a 12V ballast for a 10W bulb? Just wondering out loud here. Trying to put a favored light and favored power source together.
