I used to, but lately my technique has gotten much better. This board had 3 stacked on the lead side by RMM when I bought it, three on the spring side by me yesterday. It seems unlikely that the 3 I did damaged anything else, and if you exclude them, with 11 it should still make 4A. Iāll take a picture in a bit.
Ok. Maybe that or maybe something shorted like tiny blob of solder. I alway have correct tail measurements that corresponds to number of amc7135/8 chips. My method of tail measurements is undisputed clamp meter, and it is crazy accurate.
Some pictures of my stack job. Be kind, Iām not uber great at soldering, but Iām getting better.
362kcd on only 3.3A sounds like a lot 
Hopefully it should get a lot higher if we can get the XP-G2 S3 up to over 5-6A
Is the 362kcd measurement with the stock switch, or from when you tested the Amp without the switch?
Test direct driving it without the driver, that was i plan to do for max throw, for a hot & short run time 
I suspect your brass post (or is that an aluminum post on a short spring?) is limiting your amp slightly, those who have tested & posted results here with both a brass post & a wire bypassed spring, have so far shown the wire bypassed spring to get an higher amp.
At least on a DD or FET driver set up, i am not sure how it effects a linear driver.
What battery do you use & what size gauge on the wires?
362kcd is with the switch in place on the light.
Thatās solder on the spring, thereās a wire hiding under it.
Efest purple 26650 battery, stock wires on driver (probably 22ga).
Ok, thats solder yeah thats how i make them also, a big dab of solder on top of the wire bypass on the spring sanded flat But yours where so tidy & round i didnāt recognize it for what it was.
The Efest purple 26650 battery should easily supply what ever the driver is letting through, the only āhotterā battery i know of is the green Efest 26650, but that is only 0.3A more capable.

There are Purple 4200ma now- quite new ones, which are on thier way to me: i believe they would be better
Its true: for some wierd reason 4200 Green ones are better at 4-5-6 amps on both LD1 and A17DD drivers- i tested them alot
Maybe for high amps 3500 Purple ones would be a better option(havent tested it realy), but we dont see that often 10+ amps from a single battery in flashlights
Anyone able to post some beam shots of their setups yet?
Really keen to see what the de-domed XP-G2 will look like, as I need to order an emitter for my host.
If anyone could post a side by side shot next to maybe a stock Zeusray that would be handy. My worry going XP-G2 is the beam will just be too darn narrow.
I have a domed XP-G2 in an Aleto 26605 (giant SK68 look alike) @ 3 amps. But I find it quite useless for distance as the beam is so tiny. My de-domed XM-L2 Zeusray easily throws as well, but with a far more useful beam.
So Iād kind of like to know what the XP-G2 de-domed is like in the 1504, as I might go XP-L de-domed instead.
High lux is great, but not if itās actually useless. I can always use a laser pointer for that kind of work.
Iād recommend you go with the XP-L based on what Iām seeing right now. If the Vf is going to be the limiting factor with the XP-G2ās then the extra 60kcd wonāt make that big of a difference in ultimate throw distance.
Not the final word though, Iāll know more tomorrow.
Interesting i did not know Efest had a purple IMR4200.
I checked out there web side, and the purple IMR4200 is only a 40A, so i would guess that the 50A green one would still be stronger at under 7A.
And yes you are right at higher amp over 6A the 64A purple Efest looks to be the stronger battery.
It is really unfortunate that HKJ havenāt done a test on the green one yet.
When i checked Efest webside i saw this a IMR 35A 2800mAh 18650 purple thats looks interesting, a very unusual capacity at 2800mha i really wonder what it is based on.
And i hope HKJ soon test it because if it really are as strong as the old 2500mha purple 35A the added capacity should make it easily one of the strongest battery on the market. But we know they fudge the amp rating a bit so i wait for HKJās test on it, Efest is usually good at sending batteryās to him.
Guys i donāt know if you saw that in RMMās thread he announced that he had ordered a reel of XM-L2 U4 1Cās, those could also be a candidate for the bigger die max throw.
They are reasonably CW & should be very efficient, i canāt wait to see what they can do
They XP-L V6 1A that LEDDNA sells are suspected to only be V5ās, and if they are the XM-L2 U4 should be 2 flux bins over that
Personally, I ordered a 1405 to use with one of RMMās new buck drivers. I was planning on going with an XP-L, but I may still opt for an XP-G2. Weāll see.
Well I put together a dedomed XP-L V6 3C and a BLF17DD driver. Iām getting 4.5 amps at the tail and about 225kcd.I think the high Vf of these new emitters is going to be the bane of single cell lights.
KKW, I was pulling either 5.6 or 5.8 at the tail (no switch) with the dog dedomed XP-L V6 3C with 17DD-S08 driver and a 25R so something else has to be going on with your light.
I have yet to personally see 5amps+ on a single XP-L, you maybe have just gotten a great one.
You may be right, just reporting my results. I did scrape the wire on the diode to the right of the die, there are reports that this may raise the Vf. In preparation for this I tested it before the dedome. 4.5 amps at the tail (no switch).
Maybe Iām just unlucky and the fact that Iām not cherry picking LEDās is making a difference too.
Soldering looks good and thick but yet you never know... maybe you overheated something? Person need to be expert for drivers to reveal truth.
If I don't have good results I just toss driver in a trash(plenty of guys there :) ) and get another one. Why bother for few$?
But however I would change main spring with carobronze one.
Before you give up on that possible damaged XP-L, test direct driving it with an omten switch & 18awg wires. If you donāt get a much higher Amp then you know it is a bad one.
You say scrape the wire, if you are talking about the delicate bond wires, then yes if you have disturbed them in any way you have most likely damaged the emitter 
I donāt think my XP-L was damaged. I think you may have missed the part where my tail reading was the same before and after the dedome. I didnāt make it the clearest as it was across 2 posts.
Hehe, yes when i read them again i got that now.
I would still test a DD set up before you give up on it though.
4.5A is just so low for an XP-L on a FET or DD i think it is about the lowest i have read about here & because this is the BLF i donāt think many of us ever cherry pick the emitter.
I remember djozz did when he bought cheap XP-E2ās from Mitko to do a write up & test on it but right now thats the only instance i can remember.
