I spent a bit more time this afternoon testing both of the drivers I received.
I got rid of the cheapo jumper leads & soldered heavy gauge wire to the driver. The highest point of resistance would be where I used croc clamps to hold the DMM probes to the wires, & me holding the bare wire ends on the battery poles.
This time, I tested emitter current. Using a KK ICR 26650 at 4.17v, & the same emitter as before, I measured 5.6a on high, 2.1a medium, 0.4a low.
The second driver of the two performed almost identical.
I hope everyone who ordered some of these gets the same part - I ordered three more myself, so will see in a few weeks if I get the same again.
You are the same Moviles over at the other forum. I would recognize that mosfet anywhere.
I was over there when this driver you found was being discussed. I tried to obtain one.
A long time ago I did buy that MTE P7 sf-15 flashlight to get one of those drivers. To my disappointment it came with some other crappie driver which I changed to a amc7135 2800ma driver. Is there anywhere that sells just the driver?
I just tracked my orders the first batch of ten are in my mail box as of today. I made that order on 9/16. That was quick! The second batch of 10 was ordered the next day and they just left from Puerto Rico. That batch few right over me! Haha! The 10 that are in my mail box now came striaght from Hong Kong to Houston! I will do the testing maybe tomorrow if I have time. I would really like to wait untill I have all of them on my bench.
My first thoughts were ooh, mine could be here tomorrow! No such luck. Sheesh, shipping transit is as big a lottery as SK68s!
My driver order was made on 9/15, shipped on 9/16 (scant hours after order according to FT email and website with picture of envelope). Processed as Accepted by HKP on 9/18 and nuts there was a new update that it only just went through the HK sort facility still in HK a couple hours ago (but hopefully on a plane tonight).
After this point it will hit my box typically 3 to 5 days unless US customs holds it up at entry (and excluding times they go on vacation across, up, down, and around other parts of the country).
Well Honk Kong did just have a bigTyphoon hit over there. Im surprised mine got through that quickly. I still have 2 pakages that have not left yet. I do have tracking numbers for them though
I wonder if the Typhoon did effect a lot of our deliveries? I been watching CCTV world news. Its been pretty bad over there.
I just opened my first batch of 10 I oredered. Funny thing is I do believe their inventory is mixed up. 1 of those 10 was a east-92B driver. The FET has a different number on it than the others and the resistors are of different values. I have not tested any yet.
Hi moviles2, since both of them are capable of delivering more than 40 amp (more than enough), does it mean that the one with DTU40n06 still manage to deliver over 4A in a flashlight setup?
The order that I have with these drivers, and only these drivers, finally shipped today. This a larger order, earlier, but I removed all of the items that were not “ready to ship” in FT order status, and then, a day later it shipped. I should note that it looks like I “lost” some money on the deal though, as when they refunded for the items I removed, they apparently deducted some amount, probably for the PP fees? Nevertheless, it at least got the order moving.
I have a tracking number now, but it’s not working yet. Hopefully this tiny shipment (with just a couple of the drivers now) won’t get lost in the “X-ray shuffle” :)! Being optimistic, I’m thinking that maybe it’ll get through HK Post faster than normally, since there’s almost nothing in it (probably more bubble wrap than anything else)… either that or disappear completely…
These drivers better be darn good, with all of the trouble (and time waiting for them)!
