Only Tom and I have this so far, so it’s up to him or Haikelight.
Sorry, didn't get to it last night - worked on the runtime graph and got it scaled properly and added temperature readings.
You’re doing fine. It would have been fine if it took you waited a couple of weeks to pay your review in its entirety. What you’re doing is above and beyond.
Yea, wanted to get it out quick, figuring there were a lot of waiting. I believe mhanlen will be doing a review on it as well, or maybe that's on the MT03 flooder - the flooder would be more up his alley since he's done the Meteor and Olight X7 Marauder.
I thought I was getting the MT03, but I was surprised when I opened up the box and this one was there. I’m having trouble with battery fitment. I have button tops that work, but the battery tube doesn’t screw down all the way… So they suggested I try some HG2 flattops or 30Q flattops, and those do not seem to work. So now I have a ton of new batteries laying around. I feel like I’m just going to have to stick with button tops. I don’t think it would be possible to use protected cells in this light. I like it a lot, but it’s very specific with batteries. Probably be about 2 weeks or so before I finish my review.
I’m using batteries with brass buttons. The outer oring shows more than in Tom’s picture, which doesn’t seem ideal, but the flashlight works.
How did you get them to stick? Solder? Are they magnetic? It would just be great if I could find a battery that worked without modification. I put this stuff on my Youtube… and I like to be able to give people solid recommendations they don’t need to “rig” to get them to work properly.
I used solder. I think I got them from Richard. I should have done some prep work before I used them. They’re rough and gouge my SRK drivers. I’m trying to come up with a way to make thinner buttons with a more rounded profile, and hopefully a smoother finish, but my best plan involves using a vacuum fixture, and I don’t have a vacuum pump yet.
I also wish there were more button tops.
I have unprotected button tops in HE4, HG2, GAs, and while they all work, they’re just a millimeter or two too long, to get the tailcap tightened down all the way. It isn’t loose or anything. Thanks for the response…. looks like I’ll just be sticking with some buttons tops.
The regular flat top GA's work the best, fit the best - the tops protrude out a little, kind of like BASEN 26650's. I have no clue why they thought other flat tops would work - doesn't make sense to me. I told them I could not get them to work. Yes, 30Q BT's work, guess I didn't notice it much with the tailcap - the last o-ring was pretty much covered, but I tightened it up pretty good, but yes, not as tightened down as the GA's.
Seems like the light was made for GA's, and only GA's. The soldered low profile brass buttons would work well I'd Imagine.
Ohhh - stupid me. Forgot, I got sets of 4 of solder blobs cells, like SONY VTC6's and HG2's - they also work and fit perfect. I need them for SRK's and SRK style lights I have.
Funny, cause your BLF ID was on my box, so I figured they screwed it up and sent me the wrong one, but it turned out it was mine with the engraved "Tom E"... 
I tried some protected 35Es that are very long on the MT03. The tailcap doesn’t screw all the way in but the light works just fine as there’s no electrical path on the body.
Given that info which cells would be optimal for MT03/MT07 (performance and fit-wise)?
30Q FT + solder / GA FT?
Sounds like this light got problematics >.<
You need semi raised cells. Its touchy its the plastic protector around the tabs its either to raised or to hard and will not flex enough with pressure. But button tops are to big but they will still work fine. My HG2s work fine. You can always bend the ends out on the batteries? You could use magnets fine because the contacts dont spin the tail cap PCB stays still when you loosen and tighten the light but it may not fit still?
Am I reading this correctly? 
Like butcher the cells? Ouch boom
Yep it works they have some slack in them.
The 4S battery configuration version is now listed on the website - http://haikelite.top/index.php/haikelite-mt07-buffalo-cree-xhp70-flashlight-4s.html
The runtimes listed are still the same. Not sure if that's a copy/paste, or they didn't run the tests, or they are really the same.
Same with the MT03 4S. I was told they would be ready next week, so hopefully shipping out next week? I’ve got a pair on order for review.
Did your GA FT cells fit the same as your other FT cells with solder blobs? I’m trying to decide on 30Q FT $30 and adding blobs vs GA FT $36 stock.
Uhh, Yes. Solder blob flats seem to fit the same as SANYO GA's as-is.
