So if I understand this right, the cells are 2S2P and the LED's are 3 groups of 2S3P. Therefore, you can run the 3 groups in parallel and have a fully 2S LED setup with 2S cells, therefore a FET based driver can be used. I think that's right??
yeah you can run it DD, but it gets hot quick as it is now
with DD you may get like 25A
Yea, awesome. Just wonder if the std SRK size boards will fit. Might not have clearance for piggybacking in there? From your pics, looks pretty tight. Not sure if a SRK style driver would fit or be compatible as-is.
Beam shots are awesome! That thing is a search light. I’ll definitely be getting one!
I don’t know if they are comparable but would you describe this as Q8 killer?
For $20 it would be a Q8 killer 
. I wouldn't bury the Q8... yet. Without knowing lumens, throw and how the UI works, hard to compare. Only 4 output levels compared to smooth ramping plus multi mode sets, etc... I can also still pocket a Q8 but with the wide head on this, I don't think I could.
Plus the Q8 is a fully open source design.
Hi
I measured the driver with 47.5mm like the Q8 one
give me some time and I make one for you
How many cd it has?
This a modified version for MF-01?
yes I took the measurements in my sample and modify a SRK layout to fit
I did some minor adjustments after you quoted it
So how much do you ask for a working driver with NarsilM 
If it so, I would like to have its drawing/3d model.
depends how many want one
Oshpark sells always multiples of 3 boards
so if only one would want one thats 17.55$ for 3 boards
Prices:
17-22mm
Narsil v1.4
13.5$ Attiny85 with temperature calibration
14$ temperature calibrated, 1S LVP calibrated to any value you want
NarsilM Attiny85
12.5$ flashed no settings,
13.5$ with temp calibration and max temperature preset,
14$ with calibrated 1S or 2S LVP / temp calibration and max temperature preset, this version has no indicator LED
loose spring adds 0.3$
47.6mm add 5$ if 3 boards come together
LDO 1.2$ 21mm and bigger only
Bistro or Narsil customized modespacing adds 1-2$ depending how many groups you want changed
or you suply a hex add 0.5$
SRK Size with more than 8 AMC7135 Bank add 1$ for all 16 AMCs
so NarsilM without calibration
12.5$
LDO 1.2$
copper alloy spring 0.3$
5$ for bigger board if 3 drivers gets ordered
2$ shipping
1$ 16 AMCs
so minimum price is 22$
Dang, that was quick!! Wow, thanks Lexel!! Now we're cooking...

Great work, this light is getting better really fast.
How many lumens do you think the light will put out on the 7135’s?
What were the 12v cc chips you mentioned in the other thread?
What would it take to modify this board to use them?
Good flashlight, but… you know, after this story with S42’s short tube and ugly USB cover too hard to trust them…
When I think about thear QC, I am understand that this QC - is only checking if it’s posible to turn on a flashlight.
So, thank you, Asrolux, but NO, until full reviews and specs.
very interesting……
