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

not possible for that light, the driver cavity is too shallow and there is no high current buck atm

V2 MF01 prepped for Buck driver

Hi Lexel,
ich würde gerne einen Black Flat Treiber für die BLF GT kaufen.
Merci

I have a report of a DOA delivered driver

It was within Germany and he sent me the whole light

The driver was fine, just the new thermal enhance design does not allow a bad soldering job on the LED+ terminal

here clearly can be seen that the wire solder blob also touches the ground viases that are about 0.75-1mm next to the pad, the buck chip detects short and stops output

best is to solder the wire straight up or 180° rotated pointing to the capacitor so the ground plane is clearly visible and no short risk

Any idea how deep driver cavity is? I think there are some good coils that are 3-3,5 mm height.

you can not pass 12-15A through a 3mm high coil

I know that coil characteristics degrades while heat increase so there must have some addition over threshold, but how about Coilcraft XAL7030 series? Are those still to weak?

Definitely interested in the BLF Q8 XHP 35 driver. May need 2 or 3 of those. Where do I get the MCPCB for that?

The stock MCPCB is fine. Your problem is converting the light from 4P to 4S. Not simple when they dont use carriers.

How is that even possible without carriers? Lexel how did you get that to work?

You have a driver with 4 pads that make contact with each battery separately. Then you permanently fix the battery tube into place so the battery ends line up with the driver pads. Then you modify the pcb in the tail cap. This will supply 12 volts to the driver, but you have to load the batteries through the tail by removing the PCB each time. It’s a pain to swap batteries, but it works.

you can also build a rotating tail board with 2 pins that uses a bolt to hold to the tail cap

I’ll try to fix the qoutes.

Are the buck drivers for the MF02 to power a 70.2 still available? also do you have the 70.2 leds on the right size mcpcb for sale?

MF02S MCPCB is custom, no way to buy that stock on normal shops

Drivers are no problem

I want some 20mm XHP35 or 12v XHP50/70 drivers for two of my C8s with 20.8mm driver socket.

Already PM’d you a few days ago.

How are you going to feed 12v in a C8 size light? Double battery tube and run 4 18350?

I’d prefer a boost driver for single 18650. I’m running one in C8 with single 18650, but the size isn’t right (22mm vs 20mm) and the mode switching doesn’t work properly after sanding down.
So I just want to run C8 with some 20mm proper.

Okay, your asking the wrong person. Lexel doesn’t have any boost drivers. You need to talk to Richard at MTN E.

Hi Lexel,

Could you PM me with a price please?

I’d like to order a buck driver to replace the stock one in my MF04S, with Berylliumbronze springs and gold plated button soldered and Anduril flashed onto it, shipped to UK please.

Thanks
