The power button lights red while charging and turn green when full, I dont know if these is any low voltage warning.
It seems to draw around 450ma while charging, this drops as the battery charges.
John.
Iād be interested in knowing the parasitic drain from that e-switch. (I suspect you wonāt have to wait long djozz, as itās probably rather high. 
)
Parasitic drain is something to check too, yes.
I just removed the battery and put it in the Opus for capacity check, in the meantime I soldered another battery in 
It almost fits (had to cut away a tiny bit of plastic)
I did not check before, but the light does 130 lumen flood now. That can only be better with another led. (and thicker wires, tweaking the driver, etc.)
also looks like ...
FIX U UP DIE !
You do not even have to read it loud backwards, creepy!
Mine does not have any logo on it.
I have seen a smaller non zoomable version for sale, but I prefer the zoom myself.
I wish the high and low had a bigger spacing.
John
Double-click or single click into strobe mode? Long or short press for on/off?
So letās say 100 lumens with the original batteryā¦ thatās actually incredible for the price. Imagine that when I started this hobby I was thrilled with the maybe 15 lumens put out by this light, which actually cost more than this zoomie, and didnāt come with a battery or an integrated charger. :money_mouth_face:
No, just clicking forward: off-high-low-strobe-off-high-low-strobe-off-high etc.
The next iteration: dedomed āMitkoā XP-E2 R3 0D on a Noctigon, glued in with AA-Adhesive (because I canā¦)
Surprisingly, the output in flood has not increased, still 130lm. But for the rest:
-infinitely better tint (0Dās dedome pretty nice)
-infinitely better beam (took care of most beam artifacts, and the XP-E2 die just looks better)
-better throw (I measure 24kcd, which is about half of the max that you can get with this size lens)
Slowly this is becoming pretty decent
ā¦and the results are in:
310 mAh, not great, as expected, but not really bad either, HKJ has tested lower capacity 16340 cells.
How many amps is it pulling on hi and low ?
I canāt tell without unsoldering wires, next time I have it apart I will measure current.
I can have a guess of course for a ballpark number: 130 OTF lm in a zoomie may be 180 ledlumen, roughly times three gives current, so 550 mA ?
Low gives 25% the output of high, so maybe 130 mA ?
As requested, the current measured over the ledwire:
Next little step:
I beefed up and shortened some wires here and there and it did not help the output much.
But what are those 1.2 Ohm resistors doing in the led- path?, that is not very BLF!
Ah, that is better, howās the current now?
That helped, just doubled the current, 1.4 A is quite right for a XP-E2 on a Noctigon, with average heat path.
I guess I will have new output and throw numbers, re-charging the little light nowā¦.
Iām having a lot of fun with this light sofar! Budget lights rule once again!
Thatās the BLF spirit, djozz! :+1:
Thanks
And Iām sure if you seriously go into minimising all resistances, and solder in an Efest IMR battery, you get 2+ amps to the XP-E2 and more to lower voltage leds.
So this is called a āWOOZā as read from the picture?
Thanks for these tests Jos
Dang so short of a time I am sucked in, amazing how far it has come.
New numbers.
<5dollar-mini-zoom-USB-rechargable-flashlight, dedomed XP-E2 R3 0D on 16mm Noctigon, focusshift from thicker Noctigon repaired with extra o-ring between the two pill-parts, Keeppower protected li-ion, some wires shortened, some a tiny bit thicker, current limiting resistors bypassed:
Output in flood at 30 seconds with fully charged battery: 190 lumen
Throw at 30 seconds with fully charged battery: 38 kcd.
The throw is pretty close to the maximum that I have got for this lens (43 kcd in an Ultrafire AT-007, same type lens).
djozz, do you have a picture of the board after you removed the resistors?
I did not remove the resistors, I solder-blobbed them into redundancy, see post #27.
