I don’t understand what I’m seeing. I got my 8 yr old to touch the probes of the DMM to the cell while I held a 12ga solid lead to positive and a 12ga Turnigy lead to negative.
Before I turned it on, the DMM showed 4.08V. Turning it on in Turbo showed me 1.71V? I don’t get it? Can it really be knocking this fat 26650 down that hard?
Edit: When I took measurements the other day and posted current draw and such, it was on my JM26 with XHP-70 and the DQG Tiny boost driver. The measurements I’m taking today are actually IN a DQG Tiny triple XP-G2.
Thanks comfy, my mistake. It’s been a while since we looked at that thing. If I had taken the time to read the resistor values you listed I would have realized that you were correct!
I am neither knowledgeable or skilled enough to work on drivers. So it’s stock. I bought it to experiment if one cell would work and then picked a host when it did work.
The flash is a double flash. Low voltage according to KD.
Weird. I see that KD specifically mentions that anything below 5.7v will be detected as low voltage… but no mention is made of this only happening in “low” mode.
Does this kind of announcement from Coilcraft help us any?
Extremely low DCR (as low as 2.5 mOhms) and
ultra-low AC losses provide high efficiency across a range of frequencies (2 to 5+ MHz)
Inductance values as low as 92 nH - also optimized for high frequency operation
Superior current handling (up to 28.5 Amps) with soft saturation characteristics
Measure just 4.0 mm square with maximum heights
as low as 1.2 mm
Models qualified to AEC-Q200 Grade 1 (–40°C to +125°C) standards, making them ideal for automotive and other harsh environment applications
Doesn’t sound like a bad thing. “Soft” saturation is possibly a good thing, pending evaluation of the curves. Hopefully I’ll remember to look at this later when I’m not sick.
Well, at least shallower driver pockets with such a low inductor height. Usually it’s the tallest component and these make a 5mm driver thickness possible which is about half what it normally is at best for a boost or buck driver. Take care Alex, sci-fi, scotch, and a nice hot soak followed by what Dale recommended. It won’t cure what ails you but when else are you gonna be able to do it? Or, take two of something illicit and hopefully wake up in the morning. Seriously, get some rest dude.
We all had Gastroenteritis last week,caused by the Norovirus and sometimes known as the winter vomiting bug in the UK. I felt dreadful, fortunately the worst of it only lasted 24 hours.
Flu in late December also, I’m getting the jab next year.
Olight is coming out with a few compact 1x26650 XHP lights (5.2 inches long) which are putting out some decent lumens (R50 at 2500 lumens and L5 at 3200 lumens).
Since we can’t make one ourselves, the next best thing may be to get an Olight or….vote for the 26350 Efest battery elsewhere in this forum.
I’m probably also in the minority that would like a boost driver for xhp emitters. I’ve been searching and have been unable to find an ld-35 or anything else that’s suitable. The ld-35 is the perfect size for a courui d01 and would allow use of an xhp70 without buying another light just to use the tube.
