I did a run time test on a few of the different Li-Ion batteries I have.
Batteries tested include CR123 900 mAh Tenergy , AW 17670 1600 mAh, UltraFire 17670 1800 mAh. The light used was a Insight HX2 Typhoon w Seoul P4 led. Tenergy 900 mAh CR123 ran for 1hr 7 minutes before the light started blinking (indicating a low battery) and finally shut off. Note: On the 17670 batteries the low battery light will blink due to the fact it only has 3.7 volts/vers the 6 volts it requires from the CR123's. The AW 17670 1600 mAh ran for 1hr 15 minutes before I terminated the test. Light was warm to the touch. The Ultrafire 17670 1800 mAh also ran for 1 hr 15 minutes before I terminated the test.

James,

Thanks for posting this. I'm going to buy a few Tenergy 900mah cr's soon.

Hi, James. Thank's for posting these test results. Which do you think is the better buy from Lighthound? I see the AW 17670 at 1.6aH, as you mentioned, and the Ultrafire 17670 at 1.8aH. Price difference is negligible. Which do you think is safer/more reliable/etc.? I am probably going to buy three.

If you get a chance try out the Powerizer 3.6-4.2 RCR123's. They are known to have longest runtime for their type of battery, also able to sustain high amp drains. Your flashlight does ok with 17670 size LiIon's considering it does not provide enough voltage to satisfy requirements of the light, indicating a buck type regulator that does better with vin of batteries well above vf of emiter, and ideally well above 4 volts. Lights such as the L5 (KL5) do better with one 17670 than two CR123's. The KL5 utilizes a boost regulator.

Thanks for that info Bill ,but I'm afraid that if I use 3.6-4.2 volt Li-Ions in my Typhoon it will blow the led, the light is specifically designed for no more than 6 volts IIRC.

It depends on what type of light your going to use it in. I have 1 of AW's 17670's and 5 of the Ultrafire they both work in led lights very well. I really don't use incandescents that use CR123's/17670's. Most of my incandescents are larger lights.

I was thinking specifically of LED lights.
 
I'm surprised nobody has reported on whether or not LiFePo4 batteries are compatible with the Gladius/Typhoon. I'm not sure I can convince my co-worker to let me borrow his for the experiment.:poof:

Looks like the 3.0Vic regulated RCR123s (Tenergy 900mAh) provide the only non-blinking solution.
