V10+ 5000mA driver from fasttech not so 5000?

Dunno, but it drops down as soon as I start to drop the voltage.

Where can I get thick wire? FT has only 30 and 28 AGW

I did a 14*7135 driver and got 4900mA with the DMM in series with the standard Nanjg leads with a UR18650GM at 4.15V (offload measured). I think that driver is simply bad, too much drop in the circuit.

Fixed, thanks.

Yes - I got this IOS wire on order. Mostly I've been using this, recommended by Old Lumens:

http://www.ebay.com/itm/25-feet-22-AWG-Silver-Teflon-Wire-Red-19-Strands-/230887453205?

Available in red and black. I've found sources on eBay and Amazon.

Bought this, been using it lately: http://www.amazon.com/dp/B008XNMITW/ref=pe_175190_21431760_M3T1_ST1_dp_1

Used this on the BTU Shocker: http://www.amazon.com/dp/B0077E9KCQ/ref=pe_175190_21431760_M3T1_ST1_dp_1

The silicone has advantages for flexibility, but been finding this stuff harder to solder - dunno if it's this particular wire or what, that's why I got the IOS wire on order. The teflon coated, silver tinned solders up real well, but turns stiff, sometimes good, sometimes a problem.

I received my I-O 22ga wire the other day (‘red’ and black). Looks fine, nice and flexible. The red is more of a pinkish-orange, but who cares. I already had 20ga, but that is sometimes too thick for certain lights (HD2010 reflector, I’m looking at you).

I’m also disappointed with this driver - was hoping for a real eye-popper….

I’m getting 2.9a out of this KD 3.04a driver, but with the same kit, am only getting 2.8a out of a supposed 5a driver…

I picked up one of the V10+ 5A ramping drivers on a whim, it's pretty disappointing. I haven't put it in a light yet (and probably never will), only bench tested it so far. Current was low with only one good cell so I thwacked it with four Samsung INRs in parallel... current went up just a little but still nowhere near the rating. I can't get it to feed more than 3.8A to the LED no matter what I feed it with. And the UI is about the clunkiest thing ever.

Also, it won't fit into a P60 pill unless you solder on an extender ring first, though most uses will be in something beefier than a P60 (but then, it doesn't really need to be 17mm).

Interesting piece on paper, in person not so much.

Response from fasttech was that for them, the driver works fine.
Offered replacement or refund, chose replacement.
I haven’t finished yet with that wannabe 5A driver.

I have not found a direct drive driver which gives 5A+ with one cell and xml2 until now…
I ordered a lot of them and a Samsung inr for my tests…too sad.
The FETs they use have to much resistance or the design is crap, I am not sure why these drivers often have so much devices on them. Controller and FET should be all you need, perhaps some resistors for under voltage protection….

So now I am building one by myself.

This is all very disappointing. You’d think that there would have been extensive testing before bringing these to market. |( Whats the point?

I just swapped mine out and put the East-092 back in. It increased the output sery slightly. I think I had it close to 5A with the mods. I’ll put it in the other HD2010 and mess with it some more. I don’t like how the ramping mode is all on its own. I want to have the ramp to set one or more traditional modes. Using the ramping to change output levels in real time is pointless and takes too long.

I'm think'n 4.3A-4.4A or so is the limit for XM-L2/SinkPAD single cell lights from what I've been seeing now on HD2010 mods. That's why the T08 is so nice - wonder if you'll get closer to 5A on 2 or 3 parallel batts with this driver. Maybe I'll try it in a T08 or 7G9.

Relic38 could not get 5A at 4.20V with a power supply I doubt 2 or 3 cells in parallel would do it. And that was at 4.2V, which you'll never have on on-load cells.

No, at least mine won't. 4x INRs in parallel, still wouldn't pass 4 amps. And that was testing with a XM-L U3 on an AL 16mm bolted to an old CPU heatsink. Current went up as compared to a single cell, but still short.

They didn't have the 4A version listed when I got mine, only the 3A & 5A, so I don't think it could be a case of a parts mixup.

4xINR in parallel, I must say wow.....

Once I put the driver in another light, I’ll see what voltage it takes to get 5A. J)

8.4V :) ?

Destroying the thread but I found a solution:

ST-50 flashlight, 4.6A driver designed for sst-50 led, aspheric lens, sinkpad & XM-L2.
I am not an expert but I strongly believe that the reflector designed for the sst-50 led is not helping the XML.
