Review: KD 7135 V2 drivers 3040/2280/1520 mA with mode configuration

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.

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.

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.

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.

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.

Thanks to victori, I contacted KD with my own request and they said it should be fine, send them an order number of 5ea of these drivers and they will look into modifying them... I requested:

1. Original setup

2. Original setup

3. High - Low2 (10%)

4. Low2 (10%) - High

5. High - Low2 - Strobe

6. Low2 - High - Strobe

7. High - Med (30%) - Low (5%)

8. Low (5%) - Med (30%) - High

This should give me unlimited possibilities of modding for XPG at full power, XML at full power (by default) and adding 4 more chips for total of 4.5A for Triple XPG or Nichia... Should be awesome if they fulfill my request... fingers crossed... If they do, I know I'll never buy any other linear driver as this would cover for everything... :-)

I still wonder what microcontroller they use...

that are great news :) looking forward to your information

Same here.....

It would be nice to see this driver be able to handle using a single primary 123 battery. I don't know what would need changing in order to have that happen....it looks more specifically suited for 3.7v not 3.0v.

Can anyone spread some "light" on that for me? (pun intended :) )

got 2 of these drivers I ordered awhile ago..they flashed them so my modes are ~3a, ~1.35a, ~.070a..awesome spacing...
