I tinkered a bit with Convoy’s 12V 2,5A GT-FC40 driver. I changed it to 6V output and adjusted boost converters input limit to higher value. It was limited to 10A, but MP3431 boost converter should handle higher. I also changed bigger 1R5 valued inductor to it from broken Convoy driver. With 6,7 mOhm current sense resistor mine gives an output of 6,2A and draws 12A from battery. This with battery voltage of 4,1.
Nice MT-g2 build 1stein! did you open the reflector up at all to fit the big led, or it just worked out how you wanted it to?
Thank you! Yes, I’ve enlarged the emiter hole in the reflector to fit the LED. Furthermore I’ve put the special gasket to make the ref rest on it instead of the led, so the MT-G2 edges are secured. Everything took like one hour so it wasn’t very hard to achieve.
I haven’t done anything with my flashlights anymore for several months, but today I added aux leds to my edc FWAA. Due to the fact that attiny85 sits inside, there is only one color - ice blue, but I think that’s enough for me. imgur gallery
I also finished a mod for a friend recently. He saw it at Vinh’s and wanted it too. 7x xhp50.2 5000k mule.
Apart from the auxes, I also added a blue GITD tape to the inner wall. I think it was a good idea. imgur gallery

That is really neat…outstanding! Putting that on my list of I-should-probably-dos.
Just for fun to see what would happen and get some practical experience with flashlight modding; Convoy L2 with B35AM. Maybe a high CRI thrower.
I’m considering this a work in progress. Some practical limitations, such as no OP reflector available and unfortunately no 2 cell 6V driver (used the 20mm Convoy B35AM driver). The dedicated B35AM gasket is just too small for the reflector hole, so had to use a unknown gasket that was much thicker, but fits (possibly XP). Also the stock L2 tail button is not suitable for controlling it. Need to find a replacement for that. But I’m was pleasantly surprised by the beamshot. Was expecting something floodier, but it actually shoots out pretty straight. It throws further than the DM11 with B35AM. But up close there are rings that I would like to get rid off, just don’t know the cause.
@Verodin, I believe those rings could be reduced by a flatter, more shallow gasket. The emmitter just needs to be level with the base reflecting surface of the reflector. It really isn't that bad and the beam is nice. The color comes from the lens anti-reflective coating.
Installed an LED Lenser-type optic (out of a Jobsmart Tractor Supply Company headlight that I was planning to give away) into an S21A. Also found an e-switch that may be a good replacement for a D4 switch. The beam is a fixed, broad hot spot from the floody LH351D at 4000K. A beam kind of like a CO1S.

Today, had to run to TSC for something else and they still have these. I'm glad I had it for parts but I wouldn't pay $12.99 for an optic.
