What did you mod today?

Thank you for that comprehensive info about this topic :+1: .
I don’t have charger now but I’ll get it this weekend so we will see.
Funny thing is that this tool (wurth impact drill) is sold as a professional tool and just this battery pack costs around $170-$180 so go figure. I’ve seen BMS modules in much cheaper tools.

You're right , for this price you would expect a much better quality .., but , as sometime is happening , you pay more just for the name of a tool (or a fake one !!!) , with all the counterfeits all over the world is hard to know , for an average customer... ( who would disassemble a tool right in the store ?...)

As a good example , I got 2 Bosch screwdrivers ( needed for a house restoration ) , one made in Hungary and one in China ...Both of the them were looking the same , on the outside , same box package , made in the same year , 2017 , same price and bright new both of them . Long short story , in normal use the one from Hungary was , by far , better.., more powerful , longer battery standing , in a word , much better ! After the job was finished , I had the curiosity ( kill the cat ?...) to open both of them.., and then I understood that the China one was a ordinary fake ( smaller motor and driver , no BSM in the battery pack , internal charger with ONLY a resistor for limiting the current...!!!! But I paid the same amount of money for both ! Later , and too late , I noticed the " Made in..."

And right again , myself I saw better Quality in much cheaper tools... This is the world we are living in...

My Charger has both.
It has 4 battery contacts and is time based with a display showing the remaining charging time.
Its a “18V Ferm Premium Power” Charger.
I have to charge my new build Samsung 30Q Pack two times. If I charge it a third time, the display shows only 3-5 Minutes remaining time.

I think good and relative cheap equipment from the Netherlands.

Today the Boruit RJ-02 hypetrain chooched in to my station. I eBay-privacy film’ed it into a buttery smooth beam.

A Sofirn C8 with a LUXEON V, MTN-17DDm driver with Bistro and a Foybezel™ style bead-blasted Convoy stainless steel bezel.


How does beam look like?

Pretty nice khas, would like to see beam shots and you thoughts on the throw compared to other LED like XP-L HI. Heat and runtime on high?

Here is some crappy beam shots taken with my phone


Sofirn C8 Luxeon V


Thorfire C8S XP-L HI


Sofirn C8 Luxeon V (left) Thorfire C8S XP-L HI (right)

Both with a MTN-DDm driver and a VTC5. The XP-L HI draws 5.78A on high, and the Luxeon V 10.22 A, dropping to 9.33 @30 seconds.

The XP-L HI has the most throw and the Luxeon V has the most output. I am not the best photographer, but I will describe the beamprofile of the Luxeon V as a XM-L2 turned up to 11.

The Luxeon V puts out quite a bit of heat , I have just taken my old dog for a small walk maybe 10-15 min . I started out with a fresh VTC5 and ran it on high the whole time it did get hot but not to hot to hold. When I came home the battery was @ 3.66V and it pulled 6.22A on high.

I like the Luxeon V the tint and output is really great, but I don’t think a DD driver is best suited this LED. I have build a Eagle Eye X6 with a LD-B4 6A driver and I think it’s the perfect match for the Luxeon V because it gives you the ability to adjust the current in UI and chose between CC and DD on high mode.

very beautiful results!

Swapped the driver in mu Tool AA !
Big thanks to Giorgoskok for sending me a 15mm driver rocking Biscotti firmware !
Now all my Tool AA is missing is a decent clip to become my new EDC :

Nice one X3 !

Based on this comment on another thread I got an Eagle Eye 18350 tube and tested with my HC30. It didn’t make contact, so I used thin strips of aluminium foil roled in positioned around the driver contact edge and a strop on the tail for it to work.

What it looses in waterproofness it gains in cuteness

Hey guys, need advice, have here JetBeam RRT-2 Raptor that I need to open (driver craped out). I have general idea how to do this but that implies applying force and I wouldnt want to screw something up (wrong way) :smiley:

^it looks beautifully built! And then the driver collapses. What can go wrong with a driver?
(no ideas btw)

Grey Convoy S3 with 45 degree lens. Produces beautiful light from four E21A 5000K mounted on vr16sp4. Inside AMC7135*8 105C (3.04A) running on customized bistro-HD. One AMC7135 is connected to second star (PB0 pin) and firmware is built with support for double PWM, so really low-low moonlight and 380mA mode without PWM.

Full album.

Very nice flashlight g_damian! I assume these leds are the R9080 version?

Thank you, djozz. Yes, they are NVSWE21AT sm503-D220-L2-R9080 from Clemence.
