I'll definitely take the HD 2010 with more internal space for stacking - was already thinking I'd have to drill it out. Since I can actually get 5A out of a 4.9A Nanjg using a Powerizer, I'll definitely be doing it again (and again...).
Not sure if my post on the last page was missed, can you confirm you have received PP payment. Also add me to the list for the deeper pill for stacking, thanks.
My thinking on the o-ring, yes, I've seen it there and not there... I don't think it's a good thing having it there - the pill thread/contact is for electrical path and thermal path, so, an o-ring serves no purpose being there. It makes the connection feel tighter, but can't see how it may help the metal to metal bonding on the threads. From the pic, looks like vob left space for it and still got 6 threads.
Dunno - I wouldn't go crazy at this point. Your call to weigh the risk/delay/advantage, etc.
Thanks for that, Iāve just returned from the shop and unfortunately the machinist said that he wouldnāt be able to increase the number of threads because it was too close to the top. Sorry about that guys, but I think weāll have to go with 5 threads for now.
Some changes I made today:
-Ensured that when the HD2010 bezel is tightened down, the stock 16mm PCB has a snug fit and the 20mm copper Noctigon has a solid fit.
-Allocated 25 HD2010 pills for the extended driver space and 15 HD2010 pills for the regular profile (stock 8x AMC7135 and East-92) drivers.
-The PCB contact area will have a nice smooth finish for both pills.
Weāre initiated production, will update you guys on further progress.
Iām sure others will probably do the same but Iāll definitely be doing a before and after extended run (temp/output(lux) comparison on my 6A nanjg HD2010 (draws 5.84A on a fresh Kinoko IMR 18650). Iām keen to see what real world difference the copper pill actually makes in this host.
Iād like to see not only what run time difference it makes, but how it affects output during that time. The emitter will obviously be staying cooler, longer, so what would the out-the-front numbers look like while the run time test was being conducted? I donāt have measuring equipment to conduct this kind of test or Iād be all up into it my own self!
Maybe you posted bout this light mod, dunno, if so, do you have a link? Didn't think 5.84A on a stacked up Nanjg was possible in a single cell, at least for a high Vf demand setup with an XM-L2/copper. Copper pill should benefit this setup. I got my vob copper pill measured at 5A using a Powerizer 26650 or SONY 26650. Don't have Kiniko IMR's though - are they less internal resistance than a Samsung 20R?
Edit - ohh, the HKJ review indicates it's the same as a Pana CH. I can't get near 5A, yet alone 6A with a cell that high in resistance (0.08 vs 0.04 for a 20R) - in this thread: https://budgetlightforum.com/t/-/21733, you mention a HD2010 with an XML U2-1C, if so, then yes - can be done...
Like I said, Iām getting 5.3A on a stock unmodded HD2010 with a FourSevens Protected 26650. I havenāt been able to find a single review on this cell. I wonder who the manufactures this cell is.
On the stock East-092 driver with the stock XML/alum, I can see that - yes. Still for a protected cell, that's good. If it's 4000 mAh rated, it may be a KK cell so already has a good low resistance foundation, then if the protection circuit is well designed, you are good there. KP will OEM also, so the FourSevens could just be a KP under their own label.
Yes sorry I should have been more clear. Itās an original XML U2 on copper from led-tech. I have yet to step into doing single cell high output stuff with an XML2 so I wouldnāt know as well as you whatās doable with those emitters.
Iāll also say that I only get this high a sustained current on those kinoko IMR cells, my Trustfire 26650 5000mahs max out at about 5.4 for one and 5.15 for the other older one. They also drop faster from there.
Iām also still using the stock very thin emitter cables that came with the HD2010 so I could probably get closer to the total potential those 16x7135s if I upgraded there. 6A sounds very doable especially on those Samsung 20R
