【convoy】H4 and B35AM options are updated

Mode: 1–10–40–100 (Double click side switch ——> strobe),max output 4amps

Simon when for a 3A version of your 17mm mosfet linear driver?
I like them,single side,efficiency than AMC based

A sense resistor mod should allow 3A to be easily achieved.

I mentioned that in another thread. A 3A version would be compatible with most LEDs, and single sided drivers fit the pill in an S2+ using the retaining ring. Simon has an updated 3A driver but it’s the same 7135x8 driver from before with the newer 12 group firmware.

I agree,glad I’m not alone.
From a Mosfet driver 3A is a good amount of current for many single Led 3535 size,where 5A mean many more heat.
Yes single sides perfect to be screwed on S2+ pill.
And the efficiency Is better at lower levels current than AMC
Hope to buy It soon

This is 3A driver ,it has constant current and temp control. how about this?

Seem different layout with a lot of resistors, is affordable? Was enough get 3A by change the R010 sense resistor from the stock 3V 5A Driver?

Wish It came also with “Biscotti” FW

Awesome!

If it takes regular 26650s, one nice thing to do (especially with those long springs) would be to make the tube just a bit longer so that it could take the new 26800s.

Maybe I’m whining, but it seems to me that the black wire (minus the led) is dangerously close to the edge. In your photo you can even see that the edge of the pcb (battery minus) is connected to the led minus. I’m not saying it is so, but this is how it looks.
Needless to say, it can burn the led, because it will get too much current (direct drive)?

The devil is in the details.

You say it yourself; edge is the ground plane. Black wire and edge are connected by copper under the silk screen.

Typically the battery + is directly connected to the LED anode. If the black wire shorted to the edge ring (which is physically connected to the battery -) the would the LED not short directly across the cell, bypassing the driver entirely?

Guess it depends on where the MOSFET is located in the circuit.

Do the new 3A drivers have a constant frequency or alternating frequency strobe?

Where?

They are connected from the outside with a small amount of tin. Look on the photo.

non-PWM

Does a single-cell driver exist for the L6 that is compatible with the new FC40 LED?

But these are using what firmware? Plain old 4 mode with memory that can’t be disabled? A single sided programmable 3A driver would be perfect for a lot of host/LED combinations.

Just a personal proposal
it is possible to add groups modes on the FW for this 3A driver and others, like:
0.1% 1% 10% 40% 100%.
Where 40% mean~1.2A,good for run continuos on S2+
and these groups for limit max current of all type drivers
0.1% 1% 10% 25% 50%
0.1% 1% 10% 30% 60%
0.1% 1% 10% 35% 70%,
Maybe it give more flexibility according to the type of driver, Led and host used

Thanks, but I was asking about the strobe mode, not about PWM.
