Nice tip, +1!
The tread lock is red and nasty. It took a lot to clean the threads after. I tried mek and isopropyl alcohol, but in the end I had to patiently scrape away at it trying to avoid scratching the threads.
I opened it by holding the head in my hobby vice lined with cardboard. I put a heat gun on the joint for a minute or two watching closely to avoid fading the finish. After heated I took an old leather belt, wrapped it around the tube like a strap wrench. Then I took some channel locks and gripped the belt from the side as closely to the tube as I could. I then used the top side of the channel locks as a lever pushing down against the belt as I pushed down on the channel locks. To do this I had to pry opposite of the normal prying direction of the wrench. Finally some force and it finally broke loose.
There were two R082 resistors in paralell. I added an R100 over the top. This increased the measured current from 2.4amps to 3.2amps. However, I never advise doing this as there could be negative effects or could ruin the driver.
The parts have the same threads, however the thread lengths are different. So the cap from the 02 does not cover all the threads from the 03 body
thanks for sharing 
It looks like a little pain in the @$$ but at least we know it’s possible to mod it, thanks!
The amount of thread lock is ... incredible! LoL.
Awesome!! no problem for the H03 cap being longer, that’s a good thing actually!
As you can see the H02 threads are a lot shorter than on most other lights… in the pictures you see H02 head and cap + Astrolux S1 short tube. I doubt the H03 tailcap would be long enough to cover the oring on the S1 tube but no problem for that, I have a spare tube that I’ve planned to mod for that purpose.
Just noticed the great review from freeme here Freeme Review: Skilhunt H03 & H03F CREE XM-L2 U4 1000lm Headlamp - incomplete (I think it’s the first and only for the moment, as long as I know)
I believe the cap from the 03 will come very close to that oring. I can check later today. I have a short tube with h02 head as well. Right now I’m using that cap from a 503b and it covers up the oring. But no magnet.
wait, you mean UF 503b threads match the ones of Skilhunt and Astrolux?? That would be also very interesting!
By the way, what short tube are you using? The same Astrolux I am using?
Yes, the 503 b fits and covers the oring. I don’t care for the look though. I checked the 03 cap on the astrolux short tube and it goes up to about the center of the oring where you have it place. However, the oring can be moved to the slot right after the threads and the 03 cap completely covers the oring and it fits and looks nice.
That’s some great info, thanks
No problem. I can’t give much more information though. I showed it to a friend and… Well, I have no more light. 
I do have another one. I will be trying to open that up soon. Hopefully I can repeat the results without collateral damage.
Hey SKILHUNT, can I pay you for one of these metallic squares?
One of these:
ye i know what you mean,
i love mine, it’s light, bright, but dam that strap is tight, so much that it leaves an impression on my forehead when i take it off
one other thing is the battery compartment,
dam is that small
here’s my non edited review (so it may look like poop )
size considerations
depth of battery holder/sleave 071.93 mm minus the spring (their are some tiny components on the pcb, probably about 1.2 mm in height at one side)
depth of battery holder/sleave to spring 066.62 mm (uncompressed)
negatives:
strap is a bit tight, and i only have a small head, although it’s still reasonably comfortable
battery compartment could have been a few millimeters bigger for larger protected batteries without compressing the spring to much
Some of the Batteries i’ve tried
samsung icr18650-22e sdi 64.88mm (non protected from a laptop battery someone left at the house) fits best
xtar 68.99 mm
skilhunt mm 69.71
the skilhunt BL-134 3400mAh sticks out by 3.65mm (spring uncompressed) although it does fit with a squeeze
final thoughts
a well made light, very bright, very light weight, wide angled beam which is great if you need to light up a large area no noticeable hot spots (neutral white version)
turbo is insanely bright
9.5/10
i might buy another
dam i wondered why i couldn’t undo mine by hand
note to self must not fiddle with new stuff if it doesn’t need fiddling with 
just a quick question, is the driver board fixed in place with the thread?
I think I Need one … No… Scratch that… WANT one…
Who’s got a great discount code?
it’s a shame you didn’t post earlier, as bg had 12% off all flashlights from the 8-10th of September 
i’m sure their’l be other offers in future though
Ah, yes, the threadlocked H03….
Well, i ruined my battery tube, but i got it off…
Does SKILHUNT communicate here or just post new models?
Because it would be awesome if they sold a 18350 tube for the H03.
I have a Asrolux S1 BLF A6 shorty tube now, and it’s even cuter than the Olight Nova thingy, but it could be better.
Threads don’t match perfectly and i can’t put on the clip.
[edit] i use the 18350 tube of my Astrolux S1 now and it fits perfectly [/edit]
Maybe i can construct a shorty tube from the remains of the stock battery tube, but a real Skilhunt 18350 tube would rock!
By the way, the H03 is a great light.
It’s smaller and better looking than the H02
I have a H03F coming too, this is the best deal at the moment:

Yep, i must be mad… :confounded:
Thanks for the link Jerommel, I ordered one!
