Many thanks Doc.
Mousover version:
Tony, I've done a four-stack with these KD V2 3040mA boards to independently regulate each of 4 XMLs, and the MCU was able to control all 32 chips just fine. Just make sure that you remove absolutely everything but the 7135 chips from the slave boards. If you're using XMLs, which are pretty low Vf compared to other LEDs, you'll want to stick to the Vin range of paralleled Li-Ion cells to avoid the stacked drivers from over heating. Even 4.8V from 4*NiMH cells can quickly become too much when you're driving XMLs from a stack of these.
By the way, I love the map-light / moonlight low mode on these. It's why they're my new favorite driver.
just thought i'd mention it..kd will change the low from moonlight to 50ma if you email them..
hi all,
I would like any advice.
I'm new to modding lights.
I got the KD 8*7135 3040mah driver,when I solder it to a Xm-l emitter, I end up getting only 1 mode although I did not bridge any of the S1-S4 points. By default it should be 6 or 7 modes.
Any idea what am I doing wrong? I have followed the KD instruction sheet to solder accordingly.
Appreciate your help greatly.

Is the reflector in place? Sometimes the metal in the reflector can cause a short (should have an isolation disk over the LED). I usually just check the pill and LED with the battery first, before putting it in a host. Also check your soldering with a magnifying lens to make sure you didn't overdo it anwhere and that no wires are crossed. If you have a DMM you can do some continuity checks.

See this post where I ran into a similar problem with the older 1.4A driver. It didn't look like I shorted it, but it must have been since it fixed my problem.

Received the KD 7135 V2 3040 driver and really happy with it.
Made a P60 dropin with it using a NW XML emitter.
Just done a runtime test on low and here's my result
AW 3100mah battery
Starting Voltage: 3.83v
Ending Voltage: 3.79v
Duration: 1Day (exactly 24hrs)
Could anyone explain what to expect(Runtime on low) on a fully charge 3100mah batteries?

This happens to me all the time. The ground wire is shorted someplace usually to the outer ring were the ground wire connects. Try scraping the solder away between the ground wire connection and the outer ring and your modes should come back if not it's probably shorting to the reflector at the emitter connection.

I just ordered a completely custom modes driver. Almost nothing of the original modes remained in my spec.
At first they told me I'll have to make a 500pcs order. I asked if I can have at least 2 sets of modes custom and said I'd buy 5-10pcs. They told me that they can make my full custom modes version (and quoted it exactly) if I just buy 5 to 10 pieces and send order number.
Paid 5pcs today, sent the order number, they replied 1 hour later (actual e-mail reply to the same conversation) and said that my order is being processed.
Looks good so far. I'll send updates on how this goes. :)

How about updating us NOW on the modes you requested

Do you really want to get your hopes up and then get disappointed when I get the regular driver? :D
Hey!
I didn't say no, did I? :)
Here is a quote from Kural.
Hi friend,
We can help you modify the driver as below:
XXX 3040mA 1500mA 500mA 150mA 30mA 5mA 10Hz 2Hz Beacon1 Beacon2
OXX 5mA 30mA 150mA 500mA 1000mA 3040mA 10Hz 2Hz Beacon1 Beacon2
OOX 3040mA 1500mA 500mA 150mA 30mA 5mA
OOO 5mA 30mA 150mA 500mA 1500mA 3040mA
XOO 3040mA 750mA 200mA 50mA
XXO 50mA 200mA 750mA 3040mA
OXO 3040mA 1000mA
XOX 3040mA 1000mA 2Hz
Beacon1 is 10sec off, 1sec on
Beacon2 is 10sec off, 1sec 3Hz strobe
You can just buy 5 pieces or 10 pieces is okay, please make a order on http://www.kaidomain.com/Product/Details.S020073
After you paid, please send your order number to me and let me arrange it.
Now, I have no idea if anyone else should order custom as well. I did tell them that if all goes well I'd be telling my friends and they will get more orders.
I'm the crash test dummy again. If anyone orders, please tell me about it. Perhaps PM me and I'll tell you my order number so you can quote it if you want the same thing.

Beacon2 is sweet. I would love that.
before I got an iron w/ small tip I would do tiny stuff by stripping more of the wire, putting a little blob of solder on the end of it, putting that in place and then holding the iron onto the wire as close as i could get to the blob...
and, as for pwm - i must be the luckiest budget light guy, w/ respect to pwm - i have to try to notice it and it doesn't bother me (though, I'm sure I haven't seen the worst stuff that's out there...)
What I do is grind or file the tip down to a longer narrower point with a slight curve or hook and retin it. This allows me to get in around the other chips. A magnifying lamp REALLY helps.
Thanks guys, I'm not worried about giving it a try with the soldering iron and I quite like the user selectable modes so I'll give it a go.
Hooray for you. The difference between having and knowing how is doing.
For those with a too large solder iron: wind some copper wire around the tip.
Now, I have no idea if anyone else should order custom as well. I did tell them that if all goes well I'd be telling my friends and they will get more orders.

do you have any news? i am interested in ordering as well :)
Yup, arrived yesterday!
I got 5 pcs, one already in a flashlight, and that one works almost as expected.
Will post more info in the next few days.
