Sorry djozz, late to the party… I have already re-built my Ti/Cu EDC Quad 219C to take the new Efest 18500 1000mAh cell, it now delivers much better output with the slightly higher capacity and discharge rate. (219C emitters, x4, ran some 2600 lumens on an 18350 but now makes 3400 lumens with the 18500. )
And I’m in the process of building a 2 Cell 20700 light with a 3 pound chunk of Tellurium Copper for the pill that will run 3 of the new XHP-50.2 emitters. The goal is in excess of 10,000 lumens, we’ll see. Gotta find some 20700A’s if not the C’s… Just yesterday I spent 5 hours on the lathe and the light is taking shape. The tube is bored, knurled, threaded to fit into the copper pill, which has the driver bay ready and is mated at the top with the adaptive piece the bezel will thread onto. I have to wait now on the 63.7mm x 29.5mm triple reflector so I can finish the light. The 3 XHP-50.2’s are also coming…. it currently weighs 1442 grams, but will lose some weight with the inset of reflector and tapering/finning process.
The B cell does ok, I bored the tube of an older C8 that has ryansoh’s copper pill and the new XP-L2 emitter. With a Sony VTC6 I get slightly over 2000 lumens on this light, but with the new 20700B it “only” makes 1704 lumens. Can’t wait to see what the A cell does, when they become available again.
Thanks Heinrich, appreciate your review on these new cells and like you, am anxiously awaiting the new variant…
The only 21700 cell I have seen available for purchase (albeit with a 25pc minimum, from a company in Israel) is the Samsung INR21700-30T. Supposedly 30A (maybe 35A) and 3750mAh.
I know it is pretty hard to come by, but I would be interested in seeing these batteries tested:
Powerex Pro 2700 (these are new) and I believe are just Panasonic 2700 (2550mAh min)
I don’t blame you for being suspicious, but there are multiple reports in the other thread I linked of capacity around 1130mAh, and internal resistance as low as the best available 18350 cells.
I have both the AW and the KP 18350. So far they are rated in the Top 3 by mooch.
Top Three Performers
AWT Yellow 10.5A 800mAh
Keeppower 8A 750mAh
AW Red 12A 800mAh (button top)
Most of my lights and My 2 X 18350 lights are modded. High current is more important to me that additional run time.I just pop a fresh cell in when necessary!
