Well it looks like I can fix all these issues, but PITA they are there. Dunno if it's a 1 off occurrence though. Certainly the battery tube screws I've seen in review pics were all good, and my MT07 didn't have these problems. I've got two more Haikelite's on the way, SC01 and HT35, and plan on ordering the MT07S, so I'll be sure to check them out carefully.
Hey Tom
Does the newer MT03 have 9000LM output as they claimed?
im still tossing between Astrolux MF01 vs MT03.
I know i like MT03 design more and it’s slightly more compact.
Oh boy, don't have my notes with me and can't recall what it did stock.
My MT03 is fine so far but i never opened it up or tore it apart and i usually baby my MT03.
Ok, @home and got my notes!! I rcv'd the MT03 on May 24th, newer style w/SS square trim button, in 5000K NW tint. My test results on 4 VTC5A solder top cells (best 18650 cells around):
lumens: 9,420 @start, 9,010 @30 secs, 28 kcd (335 m) taken at 5m
Now my MT03 is doing, believe it or not: 27K lumens at turn on. Very warm in 15 secs, so couldn't do a 30 sec reading, but it dropped to ~24K in 15 secs.
Bypassing the springs made a hugh difference. This test was with VTC6's at 4.12V, ot fully charged. It has XHP70.2 P2 3B from KD, and the HQ BLF SRK v3.4 driver running a Hyperion FET. LED wires are 20 AWG, same as stock, but replaced the stock ones - even made them a little longer. Before bypassing the springs I got about 15K lumens.
27k Lumens? 
Realized last night, it wasn't the spring bypasses making such a hugh difference. In ramping, but I had a configuration problem, where max was much less than max, about 1/3 I'm guessing. The 27K was measuring in mode set operation, so it's real, just the 15K or so I was seeing was not max, probably more like ~22K.
I plan to buy the MT03 II and I need batteries. What do you recommend me? VTC5, VTC6, Sanyo GA, 30Q flat button?
Are you gonna mod it? Probably any of those would do, but the stock battery setup is for button tops only. I ripped off the plastic pieces around the Batt+ contacts in order to use flat tops, but it eliminates the reverse polarity protection.
Sanyo GA, same length as a 30Q but with a protruded flat positive contact.
Thank you both, I am going to buy the Sanyo GA that I have two at home and I only need to buy two more
Hello
Any link where to buy a good 46mm SRK driver for this MT03 ? i want to swapp my stock driver.
A 4 modes should be fine like 20lm 1000lm 5000lm 12000lm
thanks
Post #122. NarsilM will do 4 modes, but I much prefer smooth ramping - pretty incredible in this light, and 12K is way under the max in mine 
, but leaving in the stock LED's, 12K might be a reasonable expectation.
oh yes ramping seems impressive.
Where do you buy this driver ?
I bought the bare PCB from OSHPark, then bought the parts, reflowed the parts, dnld'ed the firmware. Not sure how that works overseas though, or if you are at that level.
OK and it can be find directly soldered? I’m from France
No, not as far as I know. Maybe you could try Lexel - not sure.
Yes, Lexel ships from germany: [Sold] 4. Batch "TA" Bistro/Bistro HD OTSM/Narsil drivers, 46mm for Q8 1S or 2S, Clicky or E-switch, SIR404 or http://www.taschenlampen-forum.de/threads/biete-ta-treiber-verschiedene-größen-3-7-oder-7-4v-narsilm-oder-bistro-hd-otsm.58181/
Hello
I keep you updated, I change the driver because one of my xhp70 got less output than the two others with stock driver.
Lexel send me a TA driver 46mm with narsil firmware.
Wouaaa that’s so great I love ramping in this light. And turbo is more powerful than original 9000lm.
