Anyone's ThruNite Ti2's not work on AAA Eneloops?........

Got picture but don’t know how to post. Never posted picture on this forum.

Anyone else finding this stubidly and morbidly entertaining?……

Me real-time goin’ back and forth surgerying on this poor Ti2, the gallery looking down from up in the balcony, until maybe watt’s only goin’ be left is the tail end with the lanyard loop. :laughing: :open_mouth:

YOU’RE NOT GONNA BELIEVE IT!!!

Cut another coil off the spring so all that was left was about 5mm.

IT WORKED!!! :laughing:

PS. Jon, I don’t know watt to say. This shouldn’t have werked. :student: :laughing: :person_facepalming: :+1: :beer:

PSS. I cut off enuff of the spring coil that if ya just freely drop in the Eneloop the top insulation face is about 1mm higher than the tube. That’s a lot of difference. :open_mouth:

Gad to hear that — something has you stumped though

Got er’ fixed per above thanx to Arow55!!! (He may be a mad genius or sumthin’.) :nerd_face: :student: :open_mouth:

Glad to hear it. That proves that I too am notawhackjob.

My man, this just goes to show that BLF is the BEST!!! You’re now in Notta’s Hall of Fame. :laughing: :+1: :beer:

PS. Anyone messes with Arow55 messes with me. He’s a BLF Made Man. :laughing: :cowboy_hat_face: :open_mouth:

PSS. Now I got 9 more to do. Anyone need 9 each slightly abused 5mm tall spring coil pieces? :smiley:

I just de-domed the XPG2 NW on one of my new Ti3’s. Bought quite a few at this price. Watt an improvement in tint and CRI. Instead of NW it’s definitely now a warm white. The NW IMO has a bit of a greenish cast so not so much NW, eh? Tonight I’ll see watt it did to throw and flood.

Hotspot now considerably steps all over the stock XPG2 NW on a white wall. No surprise it’ll throw further outside.

Very pleased with the results. Watt a bargain this was for $5.95. :+1: :money_mouth_face: And I certainly like that it has an AR lens to boot.

Thanks again for all your attention on the Ti2 issue. Appreciated.

Notta

Btw I wood say the de-domed XPG2 NW falls somewhere between the 219b 4500k and the 219b 3000 as shown in your above jpg link.

thanks for sharing your experience with The Ti2 arow55 Fix :+1:
I wonder if the spring in my Olight i3e is different than the spring in the Ti2?

or if your Ti2 works because the component corner is now chipped out of the way, after the number of times the light has been loaded and twisted?

here is my Olight i3e:

this is how far the battery sticks out on the stock spring:

the spring allows the battery to be compressed below the end of the body tube:

the spring is concentric so it can go totally flat:

it is gold colored:

do you see any differences to the spring in the Ti2? (I dont own one)


about Ti3:

glad youre enjoying the dedomed option…

fwiw, because the Ti3 reflectors have a large enough opening at the base, the LH351d is also a good match for modding the Ti3 LED…

Ti2’s spring is silver.

Total coils of 5 including concentric flat-top.

Coil thickness is 0.60mm.

Stock coil height is 10mm.

PS. Both Ti2’s have that biggish black chip mentioned above in the OP with the “F” imprinted on top chipped at the corner essentially. It’s a big enuff chip that you can see the toroid-like wound wiring. :open_mouth:

I think it’s a combination of me extra-torquing the head to get it to work and the coil cutback allowing contact. Butt like you said it’s a concentric spring. (???)

When you turn the head on the fixed ones it rotates down easily now so that it’s almost flush (about 0.25mm gap) with the tube step - the way it’s supposed to be. Before, there was about a 0.50+mm gap - even as I’ve said when extra-torque was applied. That’s when I’m pretty sure I did the main significant chipping on that “F” component, confirmed by the “krik” sound. :laughing:

Some all might get a kick outta this. Sealed in their boxes units btw……

Of the ten I received only one worked with an Eneloop. That one as I examined its driver components had that “F” biggish chip already with the corner nearest the positive anode showing a ‘crack’.

Hmmmmm. Someone at the factory (Sung Yu?) had obviously tried an Eneloop. :open_mouth: Couldn’t get it to work either.

Was told…“Sung Yu!!! Stop trying Eneloop! Test only alkyline! How many time tell you!”. :laughing:

Anyway, I figured leave the stock spring where it is. Stick in an Eneloop and see if it it’ll work with that chip corner already ‘pre-chipped’. Lo and behold, I hear a “krik!” as I turn down the head.

And it works.

So I remove the head and examine the driver. Sure enough the cracked corner is now completely chipped off leaving only a very very slim slice of chip plastic remaining at its base next to the anode. Wiring in the chip is now exposed as well.

There ya have it. The “F” chip being so close to the driver positive is the main culprit - not allowing the Eneloop positive anode to make full contact with the driver brass button. The 10mm long spring left intact now allows the flash to work. I think it would be pretty tuff to dremel that chip corner base down as fine as this “effortlessly” turned out. Risky because you’d be grinding so close around the tiny driver board at this juncture - much less accidently hitting other components in the process. You’d need one tiny grinding bit too. I wouldn’t do it unless I didn’t give a rat sh*t whether I won the battle or not. :laughing:

Bottom line is that you’re prolly better off going with Arow55’s coil reduction solution and just leave it at that. :student:

The Eneloop insulation face still sticks above the tube by about 4mm as it does when stock and as shown in Jon Slider’s pics above for his Olights. Previously I had mentioned that it stuck up about 1mm when the spring coils were removed to about a total of 4mm height. Well if anyone else runs into this I would suggest to get the Eneloop insulation face just even or slightly below the tube top. This means yer cutting off about 6mm to 7mm from the stock spring. That’s a lot and more than just one coil - for mine at least.

I mentioned to Arow55 that the tan version was sexy. B*tchin’ actually. I have to say it’s kinda becoming one of my favorite colors for any flash now. Makes a purrty little flash that particular ThruNite Ti2 tan shade does. :+1: :beer:

With that……

Good nite, Alice.
Good nite, Notta. See ya in a year or two. :open_mouth:

PS. I just thought about it some more. I have a hunch that one unit wasn’t tested at the factory with an Eneloop. It was likely a outside pristine warranty return that indeed worked with their alkaline batt! Oooooooo. :laughing: :person_facepalming: :open_mouth:

I dont understand how those two statements are not mutually exclusive

from where I sit, the chip in the component allows the anode to touch the brass button… the spring stuff is just a distraction, that by coincidence breaks the chip off the component during repeated screwing…

but, I dont mind how you get there, cut the spring or not… if it works for you, rock on!

and if you dont want to chip the F chip, maybe a foil ball, solder blob, or magnet, to add some height to the brass button…

imnsho, its not the spring… we know the batteries are the same length, and that the eneloop anode is 0.3mm wider

until I see a photo of an intact, not chipped corner on an F Chip, that works with a short spring, Im calling Bulloney

my bet is every Ti2 that works with an Eneloop, has a corner chipped off the F Chip, regardless whether the spring is short or long…

Ive been wrong before, when I thought I was mistaken… LOL

I know. Butt for most folks this is likely the safest illusion/delusion. Btw if it’s repeated screwing that get’s it it’d have to be quite vigorous and hard. That little chip is tuff! :laughing:

PS. Bear in mind that of the 9 I had to fix using Arow55’s method the chip in question is completely intact afterwards - no vigorous screwing necessary either. :open_mouth:

darn, there goes my perfect guesswork track record… lol
I dont understand, but, for the price, I almost dont care… :wink:

as far as the spring color, the silver ones are stiffer than the gold ones, but they should still screw down to the same body to head gap, as you describe, both cut, and uncut… or does the headgap change after cutting the spring (it shouldnt)

“……and if you dont want to chip the F chip, maybe a foil ball, solder blob, or magnet, to add some height to the brass button…”

Already tried a sizable solder blob on the brass button from the get-go. Still didn’t work. And that’s because in retrospect the tube negative couldn’t seat against the driver negative ring in combination with the stock spring made too much of a gap. Yes, I know the spring is concentric but it would also take a lot of twisting head pressure to get there and bridge that gap. Prolly would break something else too. :laughing: :open_mouth:

Ya know, Jon, maybe ya should get that 10 pak and mess with it. Like I said the 5 tan versions ya get is worth the price alone IMO. :student:

“……as far as the spring color, the silver ones are stiffer than the gold ones, but they should still screw down to the same body to head gap, as you describe, both cut, and uncut… or does the headgap change after cutting the spring (it shouldnt)”

Head gap doesn’t change.

That silver spring version is quite stiff indeed. You might be surpised even tho’ it’s concentric how much turn pressure I had to apply on the head up to a certain point.

Then I had to eventually wuss out. It won. :laughing:

“So watts the prob with this thing, Sung Yu? We see nutting wrong! Put back in new box! Chop! Chop!”

Oooooooo. :laughing: :person_facepalming: :open_mouth:

glad you are enjoying the color of your new Ti2 Tans
and
glad you managed to get all the lights working

the reason Im not buying the Ti2 is because I dont have the confidence to swap the LED, due to the plastic pill

meanwhile this is what I did tonight
Ti3, LED swap to 3500k 219b:

these have a metal pill, so the LED swap is straightforward

thanks for the interesting puzzle and conversation, and for tracking all the variables

I can hesitantly believe that cutting the silver spring makes it easier to screw the body tube to contact the pill…

I recant my previous opinions and yield to the distinguished gentleman:

prize goes to arow55 :beer:
honorable mention to nottawhackjob :student:

Nice! :slight_smile:

I don’t understand most of what you two are talking about. My simple minded thought was the spring wasn’t allowing top of tube to make contact with head. The alkaline I used was a bit shorter.
