[Sale] Buck drivers 20, 21, 22, 24, 30mm L6, MF01, MF02/04(S), TN40S/42, BLF GT, Acebeam X45/65

Hey Lexel, just got around to putting the MF02 driver in, that lame MF02, kicks some ass now, very nice work on this great upgrade of a driver! Makes me want to possibly keep it……

Maybe……

Definitely interested in the GT driver for my NW MF02! Let me know what I need to do to get this in my hands!

Kawiboy, you running a xhp 70.2 in the MF02? If so, are you running a 12V 20mm mcpcb or did you mod a 6v mcpcb to 12v?

I just fried my xhp 70.2 while reflowing it. Trying to decide what im going to do next.

25-32mm MCPCBs fit with little modification
There are Maxtoch ones or Fasttech 25mm DTP boards available you can mod to 12V

The driver needs another resistor for switching frequency if you have a 12V configured driver and you want to go to 6V LED
current stays the same

Naw just upgraded the driver in the MF02 to a 4S running a K70 4S carrier I had to shave down the diameter of the PCB’s to fit the battery tube of the MF02.

I have (way too) many 70.2’s, the 1-BLF GT, 2-Thrunite TN42’s, 2-Lumintop SD75’s, 3-Convoy L6’s, 1-Convoy L2, 2-Jaxman X6 Hunter’s, 2-Surefire M3 Combat Light’s, 1-Surefire 900A, 2-Surefire M3 Combat lights I custom made, 2-Surefire 962’s weapon lights, 1-Thrustfire T90-2, 1-Yezl Y3…just off the top of my head, got enough 70.2’s! :person_facepalming:

Interested

in which driver?

Interested in NiWalker BK-FA306 with 4S boards

BK-FA30S

Interested in driver for the MF02 XHP35 LED 2.5A
and carrier modification.

interested in one for GT+XHP70, if possible.

Thanks Lexel

@Lexel Do you have a working buck driver/sell the buck driver with NarsilM for a Haikelite MT09R?

Is it the xhp35 or xhp70.2?

The XHP70.2 version.

Lexel will need to convert it to 12v. I think it can be done since the battery tubes use replacable pcb’s. Iirc, the mt09r has the same size driver as some of his other lights using the buck driver. I’m pretty sure he can do it. We’ll have to wait till he responds for more details.

Have you asked Texas_Ace? He is working on a bunch of mt09r’s right now and is closer in Texas. I don’t know if he has a buck driver made up, but he might. It’s worth asking.

Already did pay for the driver and installation from Texas Ace.

The driver is a 16x7135+FET 2S driver if I remember well.

I just wanted to know if Lexel had a compatible buck driver, since FETs are fairly inefficient compared to buck driver.

I have right now a very powerful Buck in development, but it wont be so cheap parts only are around 40€
With it 6V and 30A are no problem

Since TA seems to keep his new MT09R driver secret to make frofit out of it
I have a similar DD driver 2 FET designed but developing to final product takes time and work and wont be better than TA variant or cheaper
Just it would be nice he shares it so Europe customers can let their lights be modded here with less expensive shipping and I usually mod a lot cheaper

Pffff! 40€ for a 50A buck driver is a excellent deal actually. No buck converter can do this on the market, even ones for high power applications, especially at only 6V.

What I would really want is a dual channel buck+FET driver pushing 7000-9000 lumens on max buck, then switch to FET above that.

Would be amazing, but I doubt that is even feasible, especially within the constraints of a flashlight driver.

Edit: Meant 30A sorry.

40€ are just the parts for 30A
development and labor add up at least another 40€
on CFT-90 LED 3.7V 40A possible

400W is possible going to 5S battery carrier would add enough voltage overhead for 30A @13.5V XHP-70.s maybe the MF03 becomes a 400W Buck if they choose me to do it
sounds odd but only add about 5.5mm Carrier diameter to fit a 5. cell

I meant 30A sorry. 50A would be complete overkill.
