Intrested for 1.
UI question.
Will this have the ramp stopping short of max, with double tap for turbo?
If so, roughly what would the % be when built for 8A xhp70.2?
Thinking I may have to get one of these along w/a couple more of the TA drivers.

The ramping can be short of 100% or be programmed to 100% as the Q8 as you wish
the code for GT is 201/255 for max ramping table

If no mod the battery carrier, Keep 2S2P.
Can be used in 6V for XHP50 or XHP70?

You need to use a simple fet driver , the Mf-01 driver lexel builds can be used .

2S/2P carrier and 6V LED can be used with normal parts up to 5A with lowered buck frequency
with upgraded parts about 8A
of course this might be well enough for a XHP50.2, but rather poor for a XHP70.2
Those are the currents to stay safe well within specification of the parts, of course it is possible to get out more but then no guarantee to operate without any issues over a long time,
if you want it just lower the sense resistors as usual for buck/boost drivers

been busy yesterday and today
12 MF02 2.5A drivers
2 MF02 6A
1 TN42 and
1 TN40 12V 8A
I think this should show the carrier modification pretty well

I made a 30mm layout that could be extended in my board program to the nessesary size or grinding down the 42mm TN42
The Curoi should be 38.5mm, if the edge clearance is small the TN42 could fit

So I did further testing of the drivers
With 2.5A Output I get on my bench test LED XHP70.2 12.31V
This means 31.02W output
to get this output the driver draws 2.075A at 16.14V
33.49W
so we ge an efficiency of 92.6% for turbo

Hey blf, we are going to mod the astrolux mf-02 to the best… of course xhp35 hi. Which parts do i need to order ?? Do i need a new sink pad? Thanks

You can use old Sinkpad it is pretty good
Just the LED seems not to be pretty good flux bin looks from my measurements like a D2 flux bin
You need just the driver, maybe also interested in my 2x2 LED board that supports up to 4 different LED colors

I have MF02 coming, would like to do this mod. I also have electrical school baground and soldering irons etc home.
Still bit unsure what will I need? Is this bolt-on mod requiring only battery serial modification for 12V supply with new driver?

Battery carrier needs mod as shown so from 7.4 to 14.8V
Then it is just replacing old with new driver
